Factors Affecting Characteristic Length of the Combustion Chamber of Liquid Propellant Rocket Engines

open access: yesMehran University Research Journal of Engineering and Technology, 2019
Optimum characteristic length of the combustion chamber of liquid rocket engine is very important to get higher energy from the liquid propellants. Characteristic length is defined by the time required for complete burning of fuel.

Trade-off analysis of a new liquid rocket engine

open access: yes, 2019
When high specific impulse and storability are mission requirements, toxic bi-propellant storable couples are very often used. Typically hydrazine or one of its derivatives are used as fuels and nitrogen tetroxide as oxidizer. Maturity of bi-propellant non-toxic alternatives is still low, even though some monopropellant solutions are coming to the ...
