Flying to the edge of space using only solar power

[@TheWinezen]

Perhaps the next version would be able to incorporate more solar cells along the fuselage sides of the plane so that the plane can produce power from rising and setting sun periods. Every square foot counts. Also, if the engine can be mounted in the rear, it would reduce the turbulence going through the entire body of the plane and increase laminar flow which will contribute to better lift and efficient power usage. You just have to use taller landing gears that will let you tilt for take-off and land more safely without damaging the rotors.

[@gordonlawrence1448]

I think a ducted prop (rather then ducted fan) is more efficient than just a prop due to the differences in tip vortex shaping. Ducted propellers work on a much larger volume of air at a lower speed than ducted fans which is how they beat them on efficiency at low speeds. They beat normal props by nearly eliminating the tip vortex issue.

[@build_itnow]

Hmm I’m curious can you explain the difference 😊

[@OddImportance]

Interesting thought, though how efficient are ducted propellers really? To further solidify the question, could the ducted propellers deliver enough efficiency to produce the required thrust at an attitude, where there is barely any medium (air) remaining? Nevertheless, would there not be modern technologies available to create//simulate as low atmospheric pressure as at the height of 80000 ft. and test different (specialized) propellers? Curious!

[@evil17]

@getehrwolf6111maybe,but the votice’s at the end of the blades is what causes certain inefficiencies too.

[@Derakday]

umm i dont think you can reach higher than 18000ft becoz : -first the higher altitude have the thiner air density, the propeller will have a huge drop on efficiency unstill stalling. -second the heat will very hard to get rip from your plane in stratosphere and you have a keep running propeller and the solar panels is also receiving the heat. Anyway I hope you can find the solutions the solve those problem.

Is not necessarily that high. Just enough to see the curvature of Earth.

[@marclagalle1486]

Heat is fixed by the drop in temperature at altitude. -60 degrees C at 40,000 feet is common. I know that there is an inversion of sorts at highter altitudes (or at least a drop in the rate of the temp going down) but heat will not be an issue.

Perlan Project Inc. is a not-for-profit aeronautical exploration and atmospheric science research organization that utilizes sailplanes (gliders) designed to fly at extremely high altitudes . The 2018 season was again based at El Calafate. The project acquired a Grob G 520 Egrett turboprop aircraft for use as a tow plane. This enabled Perlan II to be towed to 44,000 ft (13,411 m) This seems to be the highest glider tow, as records are not registered. On 26 August 2018 Jim Payne and Morgan Sandercock reached an altitude of 18,492 m (60,669 ft). This was followed by 19,439 m (63,776 ft) with Jim Payne and Miguel Iturmendi on 28 August 2018. On 2 September 2018, Jim Payne and Tim Gardner reached an altitude of 22,646 m (74,298 ft), surpassing the 73,737 ft (22,475 m) attained by Jerry Hoyt on 17 April 1989 in a Lockheed U-2: the highest manned heavier than air subsonic flight. The Perlan 2 could fly to 90,000 ft (27,000 m) if conditions allow, higher than the manned level flight altitude record of the SR-71 Blackbird at 85,069 ft (25,929 m).Previous records were measured with pressure altitude; high altitude soaring records now require GPS data.

[@endeyfire]

you also get slightly more power efficiency with solar panels the higher you climb due to the lack of particals scattering the photons away from your craft. meaning the motor can receive more power. dont... ask me more than this though. i dont know the maths or anything. im just saying anything is possible.

[@joseluiselizondo1550]

Muchas felicidades por tu proyecto . :)

[@Nanobits]

I guess nobody in the comments brought up the issue with the thin wings and lack of air pressure at that altitude. How do you get that high with so little atmosphere?

[@teenflon]

Exactly my thought, propellor aircraft have a low service ceiling due to the loss of lift and propellor performance due to the reduced density. Larger wings will increase the lift but the propellor will fail to produce enough force to keep the aircraft at a high enough speed to avoid a stall. Maybe the propellor can turn at supersonic speeds but that would add more problems.

[@randomguyinanglider]

@@teenflon the problem is more that combustion engines dont work well at that altitude, the propeller itself is not realy that much of a problem. The wings are high aspect, meaning minimal drag with not much lift, but long wingspan

A plasma cutter puts a high voltage, high Amp current through a stream of compressed air. A critically dense plasma is opaque to light and other radiation. If you focused the light from a parabolic trough mirror onto a stream of critically dense plasma, you could heat up the plasma to even more extreme high temperatures and capture much of the solar energy. A hundred square meters of solar cells costs maybe $10,000. A hundred square meters of mirrored mylar over a flexible plastic sheet might cost a small fraction. A wing tends to naturally bend up into the shape of parabola. With some aerodynamic struts to hold the exact shape, the same area could collect five tines more solar thermal than photovoltaic energy. Focused through a strip of glass covering a long slit in a cylinder, a solar ram jet could be quite simple. Solar panels also tend to be heavy. A silghtly tapered cylinder would be like a long rocket engine and possibly a lot more efficient with more of the heat working against the walls of the engine. A blast of compressed air down the middle if the cylinder that is turned into plasma at the front by a high voltage arc receives the solar energy. The walls of the cylinder would heat up from the heat of the plasma and provide more heat to the mass of air moving through the cylinder. The plasma could be extended the length of the cylinder by having more electrodes at intervals and injecting more compressed air into towards the center at a slight angle to the cylinder. But the heat from the solar might maintain the plasma at the center for the entire length. Just heading towards the sun would focus the sunlight on the plasma. If the cylinder is a little longer than the focal area, the angle of the sun to the horizon will not be as much of a factor. If the solar concentration is 1000:1, the plasma might be easily maintained for the length of the cylinder once a plasma is created at the front end by a high voltage arc. A powerful electric motor comoressor at the front and a turbine/generator at the exhaust end might allow it to use hydrogen or other jet fuel to get off the ground and up to ram speed. That would eliminate the need for a drive shaft down the middle where the plasma is. A hundred square meters of mirrored, swept wings might collect near 100,000 watts of solar energy compared to only 20,000 watts of electricity from solar panels. If the electricity from solar panels was used to create an electric arc to drive a jet engine, it would be maybe one-fourth as powerful as the concentrated solar thermal collector. With swept wings and a ram jet engine, the plane might easily get into space as it goes faster and higher in the thinner and thinner air. A little bit of fuel to maneuver in space and return to the atmosphere combined with the large wingspan to brake the plane while providing a lot of lift and distributing the heat over a much larger area might eliminate the need for a heat shield except on the most forward parts. Using subsonic air to cool hollow, forward facing parts is another option. Or interior liquid cooling. Once the plane is in space where there is no air resistance, it could deploy huge mylar surfaces to make a funnel to collect the very sparse hydrogen available in space. Accelerated to near the speed of light by high voltage plates along the length of the cylinder and confined by pulsed high magnetic field coils, the plane might travel through space at near the speed of light after a few years of solar energy from a thousand square kilometer mylar parabolic dish. Or maybe not. But it would be going pretty fast.

[@asandax6]

You missed one big glaring problem ignoring all others and that is Plasma will eat through any material so your engine isn't gonna last that long especially considering you can't make it with a heavy dense metal that'll slowly get sintered rather than quickly oblate.

[@JohnSmith-pc3gc]

@asandax6 The temperature of burning jet fuel is too high for the surrounding materials. Comoressed air is injected around the combustion area to protect the surrounding materials.

The Earth’s core is 6,700 km deep. The deepest humans have drilled is 12 km. The temperature of the inner core is "estimated" (we don't know) to be between 3,000 and 5,000 Kelvin (4,940 to 8,540 degrees Fahrenheit). The high temperature comes from three main sources. There is residual heat left from the Earth's formation, and heat is generated by gravitational and magnetic forces from the sun and moon as they tug and pull on the inner core. (The Sun heats the Earth's CORE. Sunlight is a small part of the Sun's energy) finally, the radioactive decay of elements deep within the Earth also produces heat. The Sun's total energy is NOT constant. Humans have only begun to study our star with radio, computers and satellites. Solar winds from coronal mass ejections can even change Earth's orbit. Open your mind and think. CO2 is an insignificant factor an infinite number of variables. Why don't scientists actually know the Earth's core / mantle temperature and how much it fluctuates? It's only because of deep drilling corporations that scientists have accurate measurements of crust temperature. The mantle and core temps are pure speculation. Just like climate forecasts.

[@randomguyinanglider]

When Co2 is insignificant explain how venus should be pretty much like earth relying on the mass and distance from the sun, only that venus releases all the co2 from the core which is abaut as much co2 as the earth has stored in fossil fuels and bio mass. Jes shure we cant be 100% certain how the suns power output will be in 50 jears but by basic logic and the fact that the sun is billions of jears old we can assume it will be the same, while we would fight wars over the last bit of oil we have lying around .

It is impossible to accurately predict the future using data from the past because nothing stays the same, but if you’re trying to predict the future climate of the entire Earth 100 years from now it sure would be nice to have data showing temperature, speed, barometric pressure, and direction of the jet streams for the last 100,000 years or so. Unfortunately, humans only discovered the jet streams back in 1883 and accurate measurements of the jet streams only go back to the 1950’s using primitive weather balloons. Jet stream data prior to 1883 is lost in the winds of time forever. We now have maybe 50 years of quality satellite data of the jet streams. It is impossible to accurately model the climate with so little data. However, climate scientists could build a time machine to go back and accurately measure the jet streams for the last million years, but until that happens the climate models will always suck.

We are going to show how we can do things without using fossil fuel, in plane made from petroleum products and rare toxic earth minerals mined using giant gas guzzling equipment.

Солнечные батареи тупиковый путь в развитии. И то действо, которое мы все наблюдаем в очередной раз, не даёт нам в этом сомневаться.

We should turn to renewable energy 100% soon to save our planet

[@rabingranatkagor]

это утопия. в стратосфере нет достаточной плотности воздуха для опоры крыльев и тяги винта. там надо использовать плазменный двигатель. используя энергию электричества. небольшой двигатель сможет разогнать до больших скоростей это лёгкий планер.

[@randomguyinanglider]

combustion engines dont lose efficiency during high altitude flight, so the air is sufficiently dense

[@rabingranatkagor]

@@randomguyinanglider это абсурд. двигатели внутреннего сгорания НЕ СМОГУТ РАБОТАТЬ БЕЗ ДОСТАТОЧНОГО КОЛИЧЕСТВА ВОЗДУХА. и ПРИНЦИПИАЛЬНО не могут разогнать летательный аппарат до тех скоростей, чтоб было достаточно воздуха для карбюратора и смеси бензина с воздухом. В СТРАТОСФЕРЕ. именно поэтому люди перешли на РЕАКТИВНЫЕ ДВИГАТЕЛИ. они позволяют летать на очень больших высотах. но и они не могут работать почти что в вакууме. у них тоже есть потолок высоты. именно поэтому нужен плазменный двигатель. прямоточный. но, на таких скоростях, этот самолётик развалится мгновенно !

Hate To Say It! But You Are Wrong On Fossil Fuels Solar And Win Are No Way Near The The Energy Of Fossil Fuels! Plants Use Corbin Dioxide To Make OX2 And Carbon Based Food And Lumber!!! So It's My Opinion!!!

[@DanielSilva-gc4xz]

Even If you don't care about climate changes which you should, there is still the problem that fossil fuel is not an infinite resourse and will probably in not more than a century. So we better have alternatives.

[@varathan3558]

Solar panels are far from being efficient. Even the better technology can not produce 20% (some technologies claim up to 50%) electrick power from the energy falls on the panels. So this is lower from the total amount of energy needed for transportation. Large aircrafts to lift just the pilot.

[@DanielSilva-gc4xz]

3 dimentional solar planes are apparently a thing now.

@Smiley-y2tnowadays 0,005% of the energy is from coal… and mining carbon it makes not harm but to local environment, maybe you meant when used as source of energy, and then YES, you are right about that coal is worst (while using it as source of energy) than solar that is 100% clean in the solar harvest. 👍🏼
