You can't, - it must have an engine block.
A block ring holds the engine firmly in the rocket tube. If not for this, the engine would go up the tube and the rocket would go on fire.
It is a ring that fits in the fuselage at the inner end of the engine . If this is not fitted, the engine can shoot up into the fuselage when ignited
Yes, it is definitely a model rocket if you build it yourself -that's real ingenuity.
To build a model rocket you will need a chemical rocket engine, some cardboard tubes, glue, a long rubberband, a garbage bag and a lot more. You can find a complete list of supplies here: http://www.ehow.com/how_2308899_build-model-rocket.html
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.
he was in a chinese store and saw a model built rocket. he wanted to build that rocket after himself
It is a model rocket engine that has medium strength.
Solid fuel
The Oldsmobile V-8 rocket engine was introduced in the 1949 model year.
The size of the engine you put in it.
In a real rocket, there is short a time in atmosphere and the aerodynamics are less important. In a model rocket, all flight in the atmosphere and the aerodynamics are very important. In a real rocket, it has a liquid or solid rocket engine and a large propellant mass fraction. In a model rocket, it has a solid rocket engine and a small propellant mass fraction . In a real rocket, there are four forces during atmospheric flight. In a model rocket, there are four forces throughout flight. In a real rocket, there is a long powered flight . In a model rocket, it has a very short powered flight . In a real rocket, it has passive stability and active control . In a model rocket, it has passive stability and no control. In a real rocket, it has expensive materials such as aluminum, titanium, and nickel alloy. In a model rocket, it has inexpensive materials such as balsa, cardboard, and plastic. In a real model, there is a high speed and the heating is very important. In a model rocket there is low speed and the heating is not important.
Enough to lift a small rocket 5-600 feet.
