A hybrid rocket propulsion system comprises propellants of two different states of matter, the most common configuration being a rocket engine composed of a solid propellant lining a combustion ...

Frontier, the organization backed by Stripe, Google, and Meta, announced Tuesday it is paying startup Arbor Energy to remove ...

Hybrid rocket fuel research by mechanical engineers could hasten the day when a simpler, safer hybrid engine propels space missions.

In a hybrid rocket engine like this, the fuel and the oxidizer are separated from each other and they only mix in the combustion chamber. In this case, the combustion chamber is the fuel itself!

A hybrid rocket is a rocket engine that uses a combination of solid and liquid or gaseous propellants to produce thrust. The solid fuel is stored in a combustion chamber, while the oxidiser is ...

The combustion chamber was the engine’s heart. Here, its liquid oxygen and water alcohol propellants entered through 18 injectors on the top and burned at about 2,700 ºC (4,900 ºF).

The use of fuels with a high regression rate such as kerosenes offers the possibility of building compact engines and overcoming one of the disadvantages of hybrid rockets. Detailed work on the ...

We are fascinated by the hybrid rocket engine which [Ben Krasnow] built and tested in his shop. It is actually using a hollow cylinder of acrylic as the fuel, with gaseous oxygen as an oxidizer.

This unit combines the firebox of a traditional stove with the internal stack of a rocket heater. Wood feeds through a horizontal tube into a primary combustion chamber. Hot, turbulent gasses ...

The investigation determined there was a breach in a high-pressure line carrying cryogenic liquid oxygen to the first-stage combustion chamber. The engine soon stopped providing thrust and the ...
