Just pretend it’s a 19th century torpedo, but in the air: https://maritime.org/doc/jolie/part1.htm quote:The first successful U.S. torpedo development began in 1870 and was completed in 1889. Largely the work of LCDR J. A. Howell (later Rear Admiral, U.S.N.) the Howell Torpedo was driven by a 132-pound flywheel spun to 10,000 revolutions per minute prior to launch by a steam turbine mounted on the torpedo tube.

I know it'll never happen, but imagine the hilarity you could get up to in a full 4-engine conversion to those engines. Jumbo jet pulling aerobatic stunts you usually only see from the Thunderbirds; slow vertical loops, high-alpha passes, etc.

Assuming you convert the oil, fuel, hydraulic, and ESPECIALLY lavatory systems to negative-G, you could accelerate straight up in that 747.

See Airbus marketing videos. A jet like the 747-8 made to carry a half-million pounds of cargo halfway around the world fuckin' scoots when it's only got two pilots and enough fuel to do a go-around to where it took off from.

Assuming you convert the oil, fuel, hydraulic, and ESPECIALLY lavatory systems to negative-G, you could accelerate straight up in that 747. Doing some back-of-the-napkin math: A 747-400F, empty, with GE engines, weighs 360,900lbs. CF6-80C2 engines, which normally power this type, are rated at 63,000~ pounds of thrust each. All four together make 252,000lbs of thrust, which is not enough to accelerate vertically, even with zero fuel. You'd peak at about .7 TWR and then your engines would flame out. If you change the engines to GE90-115b (which power the 777-300ER and 777 freighter, and are more powerful than the GE9X engines being tested,) the math changes. Engine weight increases from 9,860lbs/engine to 18,261lbs/engine, increasing the total empty weight by a total of 33,064lbs to 393,964lbs (and you'd need to do a bit of structural beefing up which I'm going to ignore for the purposes of this exercise). However, thrust also approximately doubles to 460,000lbs of thrust. Therefore, for a T/W ratio of 1 (a hover), you could load up 66036 pounds of fuel, which is approximately 1/5th of maximum. It's doable. Doing this exercise with only one engine converted gives you about 304,000lbs thrust against about 370,000lbs of (empty) weight, so you couldn't accelerate vertically even with zero fuel. Also you have to consider the strong yaw moment of firewalling your engines, with one of them being twice as powerful as the other three, in a vertical climb. If the airspeed dips below Vmcg, even for a second, goodbye. Tl;dr- Seems dangerous. yes, I know that's not a true 747F because of the stretched upper deck, it's a BCF or BDSF, the freighter just has the lowest empty weight

shame on an IGA posted:Ok but now do the A340-200 4x GE90-115b would be able to make it hover at about 50% fuel. I didn't put very much effort into this estimate. however, if we're doing small quad jets...  Two GE90-115b engines would give it a TWR north of two, at MTOW. The diameter of each fan would be approximately the same as the interior diameter of the cabin.

Thats about the cost of a Reaper which is produced in decent numbers already.

I was thinking about how cool a Mi 24 would look if you removed the fuselage ventrally of the wing roots and put it into a sort of high end dildo shape, maybe with Ju 87 style fixed gear, and found this neat cutaway: Entry-Level helicopter question: the fuel tanks are the stuff numbered 101 and 102, at the wing root, right?

I used the GenX because the perspective match on the source image was better (it was also easier to roughly match scale, given that the GenX is about twice the diameter of the Soloviev D-30)
