Recent Question: Recently bought BladezE550 it seems to be very jerky and only smooths out when going quite fast. The LS10E elliptical trainer offers a high quality elliptical with the benefit of power incline adjustability for those who like to change up their workout routine.
I needed help lifting it out of the box & when you string the electrical through you need someone to hold it.
Are there wheels under the front mount (at the floor) to permit the back of the unit to be lifted allowing the unit to be wheeled to another location? My console seems to be bigger, my pads are black opposed to yellow and my wheel is black and sticks our on the sides more. Hi all, I want to pose some questions to the group that (obviously) I cant figure out on my own. It's rare (as in, I've never heard of it outside textbook theoretical examples) to have any sweep on an elliptical wing. Wetted area will be a bit more than twice the reference area less the part concealed in the fuselage.
As pointed out above, while beautiful, the elliptical planform can be somewhat of a pain to build, depending of course on your material choice.
The section change from root to tip I described is often referred to as aerodynamic twist, rather than a physical one. Whether they turn out so on the actual aircraft or not we'll just have to wait and see - another year or so for the first of the projects. Since that was my main reference to airplane airfoil usage, I'm wondering if my source was mistaken? Hi all, Just up till midnight on a Friday drawing and calculating WileEZ I think you were misled. If you haven't checked your other thread, the one in the introductions forum, I asked about your intended PSRU.
Ok, so I read Riblett?s book and have gone through the motions with his foils and have come to the conclusion that the 40-215 is probably the best fit for my application. I never have trouble finding topics to discuss on Centauri Dreams, but this morning’s take was unusually bountiful. The story comes out of Yale University, whose Pieter van Dokkum led the research using telescopes at the Keck Observatory in Hawaii. The Yale team has looked at red dwarfs not in our galaxy but in eight relatively nearby elliptical galaxies, located between 50 million and 300 million light years away. Elliptical galaxies make up between ten and fifteen percent of the galaxies in the local universe, and the finding triples our best guess about the total number of stars in the universe, thereby increasing the number of planets we assume to be orbiting these stars. Image: Galaxies in the cluster Abell S0740, over 450 million light-years away in the direction of the constellation Centaurus. If a multi-billion year old civilization existed in a typical galaxy, would it have made it all the way to Kardashev Type III status, able to put to use the entire energy resources of its galaxy?
No luck yet, but what Carrigan calls ‘interstellar archaeology’ gets more and more interesting when we consider a tripling of the number of potential life-giving stars in the universe (see Carrigan’s analysis of Kardashev Type II and III signatures and his Dyson sphere methodology here). Beyond these blue-sky musings, though, a tripling of the stars in our universe could have an impact on our understanding of how galaxies evolve, forcing us to take account of the mass of a much larger population of red dwarfs than we thought existed, and thus providing a new constraint on dark matter and its effects in relation to elliptical galaxies. Say that each planet could support 10 billion persons or perhaps as many as 100 billion by completely green and sustainable infrastructure, a total of 10 EXP 35 persons may be supported simultaneously. Perhaps K III Civilizations are smart enough to figure out how to fill and control their galaxies without damming the light of all the stars? What ever the debate about how suitable M-Dwarf stars in general could be as a parent star to a habitable planet, if there is not enough Silicon or Iron or Nitrogen present to form rocky planets or to provide the chemical basis for even simple life because these ancient M-Dwarfs are metal poor then I think that is a real show stopper. Perhaps future studies of these newly discovered stars may give us a better idea of their metallacity.
Thus the idea came down to searching the LMC for stars that are brighter than they would have been if they weren’t observed through the MACHO lens. As one commenter notes that is about half a mol (Avogadro’s number, just over 6 * 10^23).
Incidentally, the *entire* universe is estimated, by Alan Guth’s Inflation Theory, to be at least 10^23 times as large as the observable universe. I am puzzled as to why the IMF for these elliptical galaxies is said to be different to that of the Milky Way, based on these figures. For example, if you look at the RECONS site (link below -and incidently this has been recently updated after I thought it had gone dead), you will see that within 10pc, class M stars make up 72% of the stars class M and above.
Then bear in mind this RECONS census is almost certainly incomplete (and the imcompleteness is in class M and lower), there would not seem to be a significant difference from the MW stellar make up in this regard. The other point I’d like to make is about metallicity and terrestrial planet frequency. Well of course eukaryotic life is vanishingly rare in the universe, as any alien life would by definition NOT be eukaryotes. As for oxygen-atmosphere planets, these may be quite common: seems to be a natural result of the bombardment of ice moons by gas giant radiation belts. Oxygen atmospheres may be common, but they would require an active mechanism to maintain them. If you are right, there will be a lot more habitable planets than there would be if I’m right.
Nick Lane makes a convincing “design space” argument for why the Eukaryote is necessary for all advanced life. Also the life of a dwarf star would be generally much longer than the sun’s life providing any companion stars would not be involved in the future of the life on its planets. I have a question related to this research: would it be possible to establish the stellar population distribution (mass, spectral type) of an entire galaxy, such as Andromeda, by analyzing the total spectrum of that galaxy?
Let us also remember, the RECONS sample is probably still incomplete for this class of star. Something else about RECONS, it depends on high proper motion detection, therefore nearby stars that have low apparent motion, or motion predominantly along the line of sight, won’t be detected (as I understand things, someone on here might know different). Therefore I think it is inevitable there are still more nearby M dwarves yet to discover, and that could push up the number proportion to 80%+ here.
Although precisely how these claims have been calculated I’m not sure, I could not find it.
I still say, I don’t see why the population is seen as a massive departure from that of the MW. As to your second post on the population distribution in whole galaxies: as I understand things, the mass-to-light ratio is taken as universal. Also let us remember, non-baryonic dark matter was invented because the rotation curve of spiral galaxies did not plot with the luminosity decrease as you move out from the galactic centre.

On CommentsCentauri Dreams publishes selected comments on the articles under discussion here. Today we’re going to explore an age-old elliptical question that many of you have probably asked yourselves at some point or another: Should you hold on to or let go of the moving handlebars on the EFX®?
As much as we wish there were a clear cut answer to this question, there are advantages to both using and forgoing the elliptical handlebars. If you want to work your upper body while getting in your cardio exercise, try using the moving handlebars. To do this effectively, increase the resistance on the EFX and make sure you’re actively pushing and pulling the handlebars. If you want to work on your balance, core stabilization and leg muscles, let go of those elliptical handlebars!
When you let go of the handlebars, your body has to engage stabilizing muscles to keep you balanced.
If you don’t want to choose between holding on to and letting go of the moving EFX handlebars, or you’re not sure which one would be better for you, do not fear! By choosing not to commit to letting go of or holding on to the handlebars, you’ll probably be giving your body a better workout.
Assuming you got the very heavy box into your house, you have only 1 moderately heavy piece to move and lots of light pieces.
The connection point at the crank as well as where the arm connects to the foot pedal are both bearings as those points take the most stress. And because the texts are written for engineering students, they assume that we all know the basics - things like calculation of the area of an ellipse, wetted areas, shear loads at stations, bending moments, etc. Now, he is a piece of work, but I am assured by people who know that his foils and wing design advice is good.
To reduce the big interference drag between wing and fuselage, try to keep the fuselage walls vertical and the section constant through the wing.
The complex curvature (surface curvature is both, chord-wise and span-wise) makes the shape somewhat involved to loft (especially without good CAD tools) and a bit of a challenge when you get to the details of designing the inner structure since every rib flange will have a slightly different angle to it and that angle will change as a function of chord position. Like you, I'm at the drawing stage with a mockup in my basement (garage in your case?) I did this to simply see if two people can fit inside a small aircraft, based on an 80% scale Spitfire Mk 14.
I don't expect an answer within seconds, but maybe it's been a while since you visited that thread, so that's why the heads up. For the past several days I’ve had two embargoed stories to choose from, both going public this PM. We’ve long known that because of their faintness and small size, getting a handle on the red dwarf population was problematic. What they discovered is that there are about twenty times more red dwarfs in these elliptical galaxies than in the Milky Way. We’ve seen robust planetary systems around stars like Gliese 581 and can assume similar systems exist in the galaxies under observation. The giant elliptical ESO 325-G004 looms large at the cluster’s center, as massive as 100 billion of our suns. What kinds of traces would a Type III civilization leave, and would we recognize it if we saw it?
That’s a helpful outcome, and it will be fascinating to see how the results of this paper are received and put to use. Assuming that one in 10 of these stars has an Earth like or terraformable planet, the number of persons such planets could support including future human explorers, indigenous ET persons, and any bodily UT persons is enourmous. Assuming a life expectancy of 1,000 years, over the lifetime of low mass range red dwarfs or about 10 trillion years, 10 EXP 45 persons could be born and live fulfilling lives. This of course neglects space time expansion, however as the limit of superluminal travel somehow approaches infinity, than for any finite level of space time expansion and finite increase in its rate of expansion, the expansion of the universe would be a trivial consideration for finite travel distances no matter how large. Alternatively perhaps they fill the spaces between the stars because that’s where all the free-floating mass is?
If there were enough normal matter in play that we haven’t yet detected, it should be all over the place, and various attempts have been made to find it.
Ofcourse there aught to be huge numbers of younger M-Dwarf stars present in these ellipticals as well. Roughly speaking, the metal poor older M-Dwarfs will out number the metal rich younger ones. Galaxies like M87 which lies at the heart of the Virgo cluster do contain stellar populations of substantial metallicity. Bohdan Paczynski (Princeton) was interested in the idea of MACHOs (massive compact halo objects) as candidates for dark matter — these might be anything from very dim stars to black holes and even Jupiter-class planets. A MACHO moving through the halo must occasionally pass in front of a star in the LMC, making it appear brighter, then fading back to original brightness as the MACHO goes past it.
The EROS team preferred to present its results as an upper limit on the number of MACHOs in the halo, with no more than about 8% of the halo in MACHOs having masses of about one-tenth to one times the mass of the Sun. Anyway, as you can see, I was wrong in thinking that it was merely occultation that these teams were looking for — they were counting on actual lensing to help them make their calculations. NASA’s supposed to announce the discovery of some bacteria that lives off of arsenic that someone dredged up from Lake Mono in California. Double it again (see my next observation) and there could be a mol of stars in the observable universe. The Great Oxygenation Event on earth did probably not (primarily) take place because of the rise of Eukaryotes, but because of saturation of oxygen sinks in the ocean and crust. Seems the former is more common than the latter, but we’ll need to watch out for astrobiological false positives from both. He suggests that some method that can provide energy for the cell with low cost in terms of number of genes necessary to maintain that structure is necessary for complex life. And according to convergent evolution (similar environmental circumstances produce similar forms and functions) something similar to the Eukaryote in functioning may be expected. They also might be a great place to find more advanced civilizations since these stars could be much older than the sun. However, if indeed these M dwarfs are some 20 times more abundant in those elliptical galaxies than in our MW, then the numeric and mass % may be even higher. In fact this seems like an unlikely population (mass) distribution, strongly skewed towards the smallest stars.

Among the criteria for selection: Comments must be on topic, directly related to the post in question, must use appropriate language and must not be abusive to others. For total body recovery, rest your hands on the moving handlebars and let them go along for the ride.
Choosing to let go of the moving handlebars also helps to engage your lower body since you’re not splitting the load between your upper and lower body.


For a total body cardio and strength workout that also works on your balance and stabilization, try alternating between holding on to and letting go of the moving handlebars.

But the allen keys supplied are a little tight for some of the places, I have my own set which made these areas easier to deal with. When you do this, the wing and the fuselage interfere a lot less, and then those huge fillets can be skipped or at least moderated.
As such, it'll probably be very time consuming to build or will involve a fairly substantial amount of tooling. Do I write about tripling the number of stars in the universe, or do I choose the first analysis of a ‘super-Earth’ atmosphere? Usually, I’ve seen a figure around 75 percent cited for the Milky Way, meaning most stars in our galaxy are red dwarfs (the Sun, a G-class object, turns out to be representative of only about seven percent of main sequence stars, meaning we live around a star that is not typical). The red dwarfs recently discovered are typically more than ten billion years old, giving life plenty of time to gain a foothold. Dick Carrigan has been studying such issues for years, looking for Dyson spheres by sifting through Infrared Astronomy Satellite (IRAS) data for objects that radiated in the infrared and carried the signature of a Dyson sphere, in which a star is surrounded by a swarm of energy-catching habitats or even completely enclosed within their shell. We do know that elliptical galaxies are made up of older, low-mass stars and show little star formation activity compared to more active spiral galaxies. If terrestial planets are still able to form will there be enough heavier elements present for life to arise? What all this means is while we may have discovered that there are vastly more M-Dwarf stars in the universe this may not necessarily mean that most of these star’s could be abodes for life.
The bulk of the halo stars in NGC5128 must have formed at redshift z?2 and the chemical enrichment was very fast, reaching solar or even twice-solar metallicity already for the ~11-12 Gyr old population. Going on the assumption that MACHOs would, even if not visible to us, warp spacetime because of their mass, he reasoned that the deflection of light in this gravitational lensing would be visible to us. Three teams of scientists went to work on this problem in the 1990s (Gates outlines all this in her book).
For a detailed look at all this, check the Gates book out, and I’ll also be reviewing a new book that gets into this in coming weeks. Moons orbiting gas giants may have Oxygen atmospheres as result of the ionizing radiation, but we have no examples of these in our own solar system.
That is not the same thing as requiring them to be members of the Eukaryota, which are a group of organisms that evolved on this planet. And this implies an even much higher proportion of all M dwarfs combined, probably well over 95%.
In the logo above, the leftmost star is Alpha Centauri, a triple system closer than any other star, and a primary target for early interstellar probes.
It’s a tough choice, but I’m going with the stars, given that the story relates to what I consider the most fascinating venue for astrobiology, planets around red dwarfs. And because red dwarfs are so abundant, the consequences for astrobiology are obvious if we determine habitable planets can orbit them. Indeed, van Dokkum talks about ‘possibly trillions of Earths orbiting these stars,’ a notion that gives still more punch to the Fermi paradox.
Globular clusters are compact groups of hundreds of thousands of stars that are gravitationally bound together. Perhaps a lack of discernible Type III activity is telling us that technological civilizations have a relatively short lifetime. Statistically, that sets up the ability to constrain the amount of dark matter such objects could represent, and it doesn’t add up to nearly enough to explain gravitational lensing in galactic clusters or, for that matter, the problem of galactic rotation. The teams did find MACHO candidates, and by the end of the decade had a combined total of 20 microlensing events from observations in both the Large and Small Magellanic Clouds.
A bunch of old red dwarfs with a bevy of possible planets, yet no ETAs in evidence, just underlines that for me.
Water worlds (we have already found one of these) will have some Oxygen resulting from the breakdown of the water vapor from the solar radiation. Eukaryotes provide one realisation of this strategy for supplying the organism with energy. To its right is Beta Centauri (not a part of the Alpha Centauri system), with Beta, Gamma, Delta and Epsilon Crucis, stars in the Southern Cross, visible at the far right (image: Marco Lorenzi). The box is extremely heavy and therefore requires 2 people possibly 3 if you all are light weights with minimal strength abilities. Considering that you are trying to fit a second seat in, you might need to do this anyways. At the galaxy’s distance they appear as pinpoints of light contained within the diffuse halo.
I suspect there will be lots of deep-freeze Earths around such stars, but very few with life powered by unhindered starlight. Even if an alien biosphere evolved some analogue of this technique to provide energy, they would not be eukaryotes as they would be representatives of a separate evolutionary process distinct from the one that happened on Earth.
Centauri Dreams is emphatically not a soapbox for political or religious views submitted by individuals or organizations. Also, rather than trying to get the box to say an 'upstairs' location, drop it to a convenient location and unpack it and take it piece by piece to its final destination. The starlight in these galaxies is mainly contained in a disk and follows along spiral arms. Finding the MAC can be done in two ways - the quicker method is to draw a straight tapering planform that approximates the shape of the elliptical wing (work out the lines so the trapezoidal approximation has the same area as the elliptical one) and then use either the geometric method, or the equation method based on taper ratio, to find the mean aerodynamic chord. Most of my references demonstrate the simpler method with barely a brief mention of the Calculus approach. Only the book by Torenbeek (Synthesis of Subsonic Airplane Design) uses the mathematical equations, although it too demonstrates the taper ratio based approximation for comparison.
Although the older five digit family has been used on everything from trainers to Cessna Citations, the sections developed by Riblett should provide you with better performance and handling characteristics. The 23012 section is not all that bad actually and depending on wing loading, does not have as abrupt a stall as the data suggests.
It is also a good example of the key characteristics you might be after: Low pitching moment, works well with flaps due to large nose curvature, relatively low drag, a wide drag bucket for decent climb performance, etc. But a more modern section should be able to deliver all that plus a higher level of assurance for good handling at low speed.
