    What an awesome project to be a part of. You did a fantastic job getting this beautiful bird in the air and busting the record. It was great to meet you out in Denver and help with the project.

    Great video.This reminds me of a contest I won at my junior high school free flight glider contest.All my school class launched there gliders with the wind and only flew a few feet before landing,me on the other hand,launched my glider into the wind,it went straight up than leveled out than soard across the parking lot high above the light poles and eventually landing in my future high school parking lot,a good 20 minute walk to retrieve my glider.I won the contest for gliding distance and altitude all this earned me a free chocolate milkshake.I really enjoyed it Since than I earned my private pilots certificate and mechanic A&P certificate and to this day I enjoy flying radio control model airplanes.Its been my love since I was 2 years old.Seeing videos like this are very inspiring to me and it's great to see young people doing it.Keep up the great work.I want my gravestone to have a model airplane purched above it.

    Dethermalizer absolutely essential. Anyone questioning that does not understand thermal soaring. In Minden, Nevada I flew a GroB 103 glider to 17,400 feet and stayed aloft for 3 hours and 45 minutes. I only came down because I was freezing (not dressed appropriately, who knew?). I could have flown a lot higher (yes I was on oxygen) but the cumulus cloud base was popping at 17,000 and that held me down.
    I was climbing about 1,000’/minute. Never underestimate thermal lift!

    • @joshuawfinn

      We have purely used the DT for obstacle avoidance. That was its main goal from the start, as well as aborting a flight attempt should the model begin drifting toward sensitive airspace.
      In terms of rubber, you would be stunned by how much is produced and consumed. It's absolutely mind boggling. This thing uses a lot, but it's not even a drop in the bucket.

      @aeromodeller1 Рік тому +2

      Thinner air is not helpful, but the cold also reduces the energy capacity of the rubber. Internal combustion engines will develop less power in thinner air, but that does not afffect rubber. The airplane has to fly faster in thinner air. The propeller must turn faster, reducing the motor run time, reducing duration.

      This is an R&D project with tremendous overhead. The cost of the materials to make the plane are a small fraction of the total. The cost of the next plane will be less and the more he makes, the unit cost will go down. The Wright brothers estimated that they spent a total of about $1,000 to get the 1903 machine to fly. Bringing that forward at a 1.04 per annumm inflation gets $110,662.56.

    We continue to learn everyday and it is something in modelling that I would like study more is whether we scale the model or scale the physics. Not everything behaves in a linear fashion and and the margins of stability, speed & strength will require careful picking around. After all engineering is about getting the right compromises. I first thought of this with steam powered models and then scale speed as things like mach numbers are where they are and the transistion gets farther away the smaller the scale. The torsion problem is an interesting one and I started thinking about contra rotating rubber bands to balance the torque/torsion in the fuselage with a gear box for the propellor. This could reduce the torsional load overall although prop reaction would still figure in.
    Looking forward to this bird catching a thermal although the seasons are now moving against us until the spring, at least for us northern hemis.

    Hey Joshua, don't you think that a little bit of torsional flex in the aft fuselage is actually a good thing? If the lifting horizontal stab tilts slightly away from the edge of thermal, it will cause a yawing moment turning the aircraft *into* the thermal. Great video! How about a visit to the Lost Hills Model Free Flight field in California's Central Valley in the Spring when the air is cool, the density altitude is manageable, and the thermals are booming? BTW, keep working on your 'body english' to remotely control the aircraft using telekinesis. 😉

      Main thing is the up and down bending of the tailboom attachment, which is changing the incidence in flight.
      We talked about Lost Hills but the orchards are a problem. Current discussions are surrounding Utah, Nevada, and southern Arizona as possible locations. There's also another site in Colorado that might work well.

    Looks like you've got a real shot at bagging some records with this one!
    Have you guys considered using a couple smoke generators upwind to better assess thermal conditions?
    Smoke systems on ag planes work great to determine wind direction better than streamers and detecting low level thermals that affect our application.
    I've watched smoke lay on the ground on one edge of a field and a quarter mile away it's already heading for the stratosphere...

    • @joshuawfinn
      @joshuawfinn  Рік тому

      This is a good idea. Do you have any suggestions of where to get such smoke generators? I'd really like to do some studies like this.

    • @Skinflaps_Meatslapper
      @Skinflaps_Meatslapper Рік тому

      @@joshuawfinn If you'd like a handheld unit that could be powered from a small portable generator, I'd suggest the "rocket" from pea soup. It uses the same non-toxic water based smoke juice that fog machines use, but it's an industrial version meant to simulate smoke for firefighters and whatnot. Not what I'd consider cheap, but maybe you could swing a sponsorship or something?
      In our planes, we simply pump smoker oil straight into the exhaust using a Compro smoker system. It's the same type of system that aerobatic planes and skywriters use, but it can also be used on virtually any engine...car, truck, ATV, generator, lawnmower, etc. Rather than spending a ton of money on a STC'd certified part, you can make one of your own with a cheap 12V fuel pump, a gas can plumbed with a small hose going to the pump, and then a small nozzle in the exhaust to pump the oil into. If installing in a vehicle, inject the oil past the cat converter and any O2 sensors to prevent damage. It'll pass through the muffler and beyond indefinitely with no ill effect. Flip a switch to turn the smoke on, and as long as you're pumping oil into the exhaust it'll keep on generating smoke. You could drive a vehicle upwind back and forth so you'll have a "wall" of smoke to visualize any thermals or dead air heading your way. Wait until you see a particularly high column of smoke heading you way and launch into it. Alternatively, go to harbor freight and pick up a few of the cheapest pull start engines for pumps/generators, or source them used locally, rig them up with a little smoke system, line a few upwind of you, and just let them run for a while until you see a good thermal heading your way. A little engine like that can be rigged up with a pump up chemical sprayer and a brass hose barb pinched down to use as a nozzle, total cost might be $30-40 plus the engine.
      Kitplanes has an article about how to build your own "$250 smoke system" that you could use to get an idea of what you might need to rig up a vehicle for that purpose. It doesn't have to be to the same standards and you could probably make something comparable for under $100. You'd benefit from more oil capacity though, since my 1.5gal tank doesn't last all that long even when I'm using it sparingly in short little bursts. A fuel tank for a small boat might be just the ticket to fill with oil and toss in the bed of a truck. You get best results from a fine mist going into the hottest part of the exhaust. The more oil you pump in, the thicker the smoke will be. The finer the mist, the better it'll burn, and same goes with hotter exhaust...if you get those two down, the smoke will hang longer. Using proper smoker oil will give you the best results as far as smoke quality, clear and light oil generally does best. I've used what's called "ultra clean spindle oil" in my smoker and it's nearly as good as name brand smoker oil. However, I've also seen tractors injecting straight diesel into their exhaust to produce some good clouds of smoke too, it just doesn't work so well on turbine engines flying at 170mph. I believe the military injects diesel into their tank exhausts to create a smokescreen for assaults and whatnot, so maybe it's worth experimenting with.
      If all that sounds like too much work or expense, you can get smoke canisters online that are way better than the little fourth of july smoke bombs. Try surplus and airsoft stores, they'll either carry them or tell you where to find them. Get a few volunteers to light them up and keep an eye on them to make sure they don't start a grass fire. Cheap and easy solution for the most part. Another idea with some potential is using battery powered leaf blowers and a couple pounds of flour for each, point them up and feed a scoop of flour into the intake. Not sure how well that would hang but it might be long enough to visual air currents, dust from driving down dirt roads can hang in the air for a long time and makes temperature inversions easy to spot. Certainly sounds fun enough to experiment with at any rate. Good luck!

      We never maxed out the torque. Winding to 150+ in-oz in hot weather at high elevation is brutal. The motor can take 270 in-oz but I just couldn't wind that hard. As you noted, the glide is beyond amazing, less than 1 ft/sec and flatter than anything else out there.

  • @aeromodeller1
    @aeromodeller1 Рік тому

    Fantastic! 5 minutes, still air, easily. You are flying with close to apogee torque. Knowing that allows selection of rubber cross section for maximum still air time; apogee torque = average torque on the motor unwind curve. You will need to put in about five times as much torque. Need a winder with 5x more gearing, may need a winder with lever arms for two man operation, maybe two to hold while a third cranks. The propeller is much too small. The blade angle distribution likely could be improved. Every comercially purchased prop I have measured has been badly pitched. If you knew the revolution rate and airspeed, you could calculate the advance angle and atack angle at each radius. Ideally the attack angle would be uniformly the attack angle of maximum L/D across the radius. These things can be measured.

    • @joshuawfinn
      @joshuawfinn  Рік тому +1

      I figure about the same. The thin air at 5k ft elevation makes it kinda tough. We only had a few hours of conditions suitable for really going at it and small misjudgements made that less productive than I'd hoped, however it still looks great in the air and that's what most people care about.

    Ever consider power comparisons with 3 blade prop or a toroidal blade?

    • @joshuawfinn
      @joshuawfinn  10 місяців тому +1

      3 blades is always less efficient than 2. You only use more than two if prop diameter is restricted by other factors such as landing gear length or ultra high speed flight where two blades would go transonic. The toroidal blades have proven extremely inefficient, which is not unexpected. It's an attempt to get something for nothing.
