Enough to lift a small rocket 5-600 feet.
The size of the engine you put in it.
A model rocket usually only holds one engine. The size of the engine and the amount of thrust that you get from varies. Becoming apart of a model rocket organization can help you determine the right engine for your rocket.
The thrust generated by a Pratt and Whitney PW4000 jet engine can vary depending on the specific model and configuration. However, these engines typically produce thrust in the range of 52,000 to 98,000 pounds-force (lbf) during normal operation.
Lift, drag, thrust, and gravity.
In a model rocket that uses engines, there is an engine mount. The engine mount is located inside the body tube in the bottom where the engine goes. It usually consists of a small tube, two rings that connect it to the body tube, and a metal bar to hold the engine in the tube. Its job is to house the engine and hold it in place for a flight. glad to help, Uujjee
Thrust (due to solid or liquid fuel burning)
It is a model rocket engine that has medium strength.
Solid fuel
Fuel core grain. The core is either an end burner (low thrust), core burner (high thrust), or a partial core burner (high thrust initially then low thrust as it transitions to end burning).
F = m Am = 0.19A = 11F = (0.19) x (11) = 2.09 newtons upwardBut there is another force on the rocket = (m g) = (0.19) x (9.8) = 1.862 newtons downward.The engine also has to cancel this force.Total engine thrust required = (2.09 + 1.862) = 3.952 newtons.
You can't, - it must have an engine block.
Thrust, and lots of it. for about $25 bucks @ you're locale hobby store, you can buy a model rocket kit that uses the same basic idea's as nasa's
