Is it possible to stop thrust in a solid fuel rocket?

Once the burning starts, it will proceed until all the propellant is burned. With a liquid rocket, you can stop the thrust by turning off the flow of fuel; but with a solid rocket, you would have to destroy the casing to stop the engine.

Can you shut off a solid rocket once ignited?

Once it is ignited it is impossible to shut down a solid propellent in a rocket because they have all the necessary things ( fire, oxidizer,fuel) to burn . When thrust is desired, a suitable ignition source is introduced in the combustion chamber and the valve is opened.

Can a solid fuel rocket reach orbit?

As to your question, yes, it is theoretically possible. In fact, there have been a few amateur made rockets that have reached the Kármán line. The first happened May 17, 2004, by the Civilian Space eXploration Team (CSXT).

Does rocket fuel go bad?

It doesn’t have all the additives of gasoline, and it won’t decompose over time. However it must be kept at insanely low temperatures to prevent evaporation.

What does NASA use for solid rocket fuel?

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.

How much does a solid rocket booster cost?

Is it possible to develop an aerospike rocket engine?

Progress has been made with NASA testing small-scale solid rockets with a toroidal full-length aerospike in 2004 but since then there has been no large aerospike engine development.

What kind of engine is in the prospector rocket?

CSULB students had developed their Prospector 2 (P-2) rocket using a 1,000 lb f (4.4 kN) LOX/ethanol aerospike engine. This work on aerospike engines continues; Prospector-10, a ten-chamber aerospike engine, was test-fired June 25, 2008.

Why don’t we use more than one rocket engine?

With a rocket engine like the aerospike, you can use just one engine that will work efficiently from take off to space and avoid the need for multiple stages with different rocket engines optimised for different altitudes, effectively becoming an SSTO or Single Stage To Orbit. So, if these are so good why aren’t the used.

What is an aerospike and how does it work?

This is what an aerospike does, and it uses the pressure of the air surrounding it to have the same effect as the bell of a traditional rocket engine. The two main types of aerospikes which have been developed are the annular or round ones and the linear or straight ones. The round ones are where they get their name from.
