What is the basic requirement of solid propellant rocket?

The choosing of propellant type is at the core of any solid rocket motor design. The desirable characteristics for a solid propellant are high specific impulse, predictable and reproducible burning rate and ignition characteristics, high density, ease of manufacturing, low cost, and good aging characteristics.

What is the most efficient solid rocket fuel?

The LH2-LOX propellant has the highest specific impulse of any commonly used rocket fuel, and the incredibly efficient RS-25 engine gets great gas mileage out of an already efficient fuel.

What fuel is used in a solid rocket booster?

aluminum
The solid fuel is actually powdered aluminum — a form similar to the foil wraps in your kitchen — mixed with oxygen provided by a chemical called ammonium perchlorate.

What is the best fuel for model rockets?

The best fuel for solid rocket propelant would be (from strongest to weakest): Petroleum jelly, eg: Vaseline, or other “gel-like” hydrocarbon. Kerosene (doesn’t mix well with solid oxidizer) Glycerol (soluble with Potassium chlorate)

What are the disadvantages of using solid propellants?

Two disadvantages of solid propellants are the difficulty in varying thrust on demand (i.e., solid fuel rockets generally cannot be throttled or operated in start-stop mode) and relatively low specific impulse (time integral of the thrust per unit weight of propellant), Isp, in comparison with liquid fuel motors.

What is the best oxidizer for rockets?

Fluorine is not only extremely toxic; it is a super-oxidizer, and reacts, under the proper conditions with almost everything but nitrogen, the lighter of the noble gases, and things that have already been fluorinated to the limit. And the reaction is usually violent.

What is the best propellant for a rocket engine?

In the early days of experimental rocketry powdered zinc and sulfur were a common propellant. This was also referred as “micrograin.”. The optimum mixture was 2.04 parts zinc to one part sulfur by weight.

What is the oxidizer used in rocket engines?

Virtually all motors for amateur use and most composite propellants for commercial or military rockets use Ammonium Perchlorate as the oxidizer. The oxidizer comprises 50\% to 80\% of the total by weight. The fuel is usually a powdered metal, either Aluminum or Magnesium.

What are the different types of propellants?

The three most common types of propellants are compressed powder, usually black powder, sugar propellant (most commonly sucrose, dextrose and most recently, sorbitol) and composite propellant using ammonium nitrate or ammonium perchlorate as the oxidizer and a powdered metal (usually aluminum or magnesium) as the fuel).

Who are some famous experts in rocket propellants?

There are three well known people who are “experts” in each of these propellants: David Sleeter (Teleflite Corporation) has a book on black powder motors “Amateur Rocket Motor Construction.” John Wickman has a book “How to Make Amateur Rockets” and his propellant of choice is composite propellant.
