Powered Airplane Motor
Can u pls point me out a lil in physics, mechanics..?
An ascendant airplane on h=4.9km height reaches v=420km/h speed . Find ratio between the mechanical job ( or how u translate it..:P) of when the motor has to combat gravity and between the mechanical job ( when power in multiplied by length) of when the speed has to grow during takeoff...
a 7.2
b. 5.4
c 1.8
d 0.36
Neglecting wind resistance, the work (not job :p) required to bring the plane from 0 to 420km/h is equal to the kinetic energy, ½mv², where m is the mass of the plane and v is the final velocity. The work required to lift the plane 4.9km is equal to the potential energy, mgh, where g is the gravitational acceleration, and h is the height. The ratio is mgh/(½mv²). The mass cancels out, and the result is = 2(9.8 m/s²)(4900m)/[(420000m/h)/(3600s/h)]² = 7.056 ~= 7.2 if you use g=10 instead of g=9.8.

Garry's Mod 10 Engine-Powered Airplane (Part 1 of 2)
i an totaly ignorant about all what aircraft?
what defines a ultra lite aircraft?what about ultralite horsepower?? how small are smallest airplanes that are not classed as ultralite and how mutch horsepower do the motors on these aircraft generate? does the military use any of this type of aircraft? now ,how mutch horsepower is / was the largest piston powered aircraft motor that ever went into production
An ultra lite plane is in a class by itself and by FAA definition of an airplane, does not qualify as such. The military, to my knowledge, do not use such light aircraft. Air and Space magazine just published an article on the worlds smallest planes. One had a wingspan of about 12 feet and was powered by an engine of about 25 hp. The most powerful piston engine ever produced, I believe,was a Pratt and Whitney double wasp engine that produced 2,500 hp.
