What type of engine does a model rocket use?

Answer 1

Most hobby rockets engines are constructed of wood, plastic or paper, many different kinds of accelerates can be used.

Please see related links below. There is gunpowder in the engine

Answer 2

A model rocket is the entire rocket which goes up into the air. It usually contains:

• Main Body
• Nose cone
• Nozzle
• Rocket engine
• Payload (Parachute)

The model rocket engine (or rocket motor) is the part of the rocket which contains the propellant. It is generally a cylindrical tube which fits into the main body of te rocket.

To understand better, you can compare it with a car. The model rocket is the entire car, complete with the interiors and the body. The model rocket motor (engine) is only the IC engine of the car.

Answer 3

Ordinary model rockets use solid fuel engines. These are often made by the Estes company. Inside the cardboard engine tube is a propellant with a hole in the middle for the igniter. Often the propellant is Black Powder.

Higher power model rocket engines use a composite propellant (similar to what NASA used for the Shuttles). Many of these types of engines are reload-able and reuse-able.

Hybrid Engines use a combination of Nitrous Oxide in a small pressure tank and propellant. These engines are reload-able, altho' the skill level to use these is higher.

There are liquid fueled model rockets but these are highly specialised and often for research and development. It is very rare that a model rocket will use liquid fuel as propellant due to complexities of storage, ignition, cost of materials and the fuel itself.

Answer 4

1. The letter is the engine power class, each letter up the power doubles
2. The number before the dash is the thrust (I think in Newtons)
3. The number after the dash is the ejection time delay in seconds

• A8-3 is in power class A, thrust 8, ejection time delay 3 seconds
• B8-6 is in power class B (2*A), thrust 8 (same thrust but will burn twice as long as A8), ejection time delay 6 seconds
• D12-0 is in power class D (8*A), thrust 12, ejection time delay 0 (for staging)
• D12-10 is in power class D (8*A), thrust 12, ejection time delay 10 seconds

There are also 1/2A and 1/4A engines for very light rockets.

Answer 5

No, that is far too dangerous.
