how can I??

Question

how can I get the best power to weight ratio in a homemade jet engine,what fuel works the best, and how do i make it more fuel efficient?

Answer 1

if power is somewhat governmed by not wanting to blow yourself up, the answer is to reduce weight. but of course not detracting from structural integrity. so depending on the size of what you are launching, use balsam wood or aluminum, or if you are made of money, get some carbon fiber.

Answer 2

Jet engines are extremely inefficient, try using a diesel engine instead. They are over 7 times more efficient than jet engines. They weigh more but you only need to carry 1/7 as much fuel.

Answer 3

is it a propulsion jet (jet airplane) or a turbine used for horsepower(a helicopter, prop driven).In any event they use a highly refined fuel such as JP-4 in jet fighters and JP-8 in heli's as far as efficiency it does depend on many factors. The first is your fuel control mechanical verses digital it really depends on how much you want to spend.It also depends on your aircraft type so you have a little research to do.Try checking with Pratt & Whittney they have one of the best engines ever built the PT-6......Good luck
