To name a few, Innovative Wings built the World’s Fastest Single Engine Turboprop Aircraft (experimental or otherwise). Takeoff was a straightforward procedure. Recent demonstrations of VTOLs and robo-taxis have all been powered by batteries, with only 5–10 minutes of operating time — hardly sufficient for practical use. However, at Cessna (152) speeds, props are vastly more efficient, so a $turboprop$ is not out of the question and, indeed, these are found on crop dusters. This is why removing the engine in front and placing jets in back is out (unless you want to really go crazy and mount a Gatling in the front). Sure, they are used in hoverboards and other doohickeys that are even slower than a C-152, but the reason they are used in such applications is their size and relative safety compared to piston engines with large propellers. “We needed to maintain the high performance of a very large engine while drastically reducing the costs and size,” says Jean-Michel Guimbard, co-founder and chief technology officer of turbomachinery at Turbotech.

This was a big challenge, but it was made possible by our collaboration with ANSYS.". I myself was thinking of adding triple microjets on both wings, for redundancy. For over 50 years, our 320 series engines have flown hundreds of thousands of hours. removing the engine from the front causes nose up, adding the engines under the wings causes nose down when idling. Clearly, if you want to be airborne, the extreme weight advantage of the hybrid-electric turbogenerator system is the only way to go. It can also be adapted to run on hydrogen for a completely emission-free flight. With logs $10,000 apiece. An aircraft with an extra ton just won't take off, so the higher energy density of the turborgenerator is needed to make these vehicles viable and flyable. (STX spoilers). Adding fuel tank to the nose instead of the engine helps little as sooner or later the nose fuel tank is empty and again the forces need to be countered. The mechanical integrity of the heat exchanger is critical to performance and service life. This 55-kg (dry weight) turbogenerator provides 55 kW of continuous power running on Jet-A1, diesel and biofuels. Making statements based on opinion; back them up with references or personal experience. The mini jets are stupid loud. I'm not sure if this post is just trolling, or the OP really considers this to be an option. Another 40 kg of fuel doubles the power yield to 260 kW-hr in a 135-kg package, while the equivalent power in Li-ion batteries would weigh two metric tons. put a more aerodynamic nose on it? You'll need to convert it over to experimental and do a whole lot of flight testing before the FAA will sign off on it. I thought since they would be outside the fuselage they might be quieter. The TP-R90 was created to fill the need for lighter, quieter, more reliable and less expensive replacement engines. Reference 2 gives a de-tailed review of the effect of seal clearance on performance of transport and fighter engines. Sequence of antiderivatives of a continuous function.
