Influence of rocket design parameters on engine nozzle efficiencies

30th Joint Propulsion Conference and Exhibit, 1994
Using a modified version of JANNAFs Two-Dimensional Kinetic Program (TDK), parametric calculations of rocket nozzles were performed. Efficiencies of energy release in rocket engines are defined. The domain of nozzle losses is classified by two-dimensionality, frictionand kinetic.

Inviscid Nozzle for Aerospike Rocket Engine Application

Applied Mechanics and Materials, 2015
A computational method for the steady 2-D flow in axially symmetrical rocket nozzles with a given profile is developed, in order to determine the Maximum thrust contour of rocket engine nozzles with large expansion ratio. The optimized nozzles proved a more than 10% increase in the integral specific impulse recorded during the variable ...

Simulation of a Rocket Engine Nozzle Discharge Coefficient

Russian Aeronautics, 2018
Multiparameter studies of the discharge coefficient dependence on the nozzle geometry and the presence of a condensed phase in combustion products were performed. The simulation results obtained satisfactorily agree with the well-known generalized data.

Using an adaptive nozzle to improve rocket engine performances

2022
One of the best known problems in the design of liquid rocket engines is the adaptation of the nozzle to a given mission - i.e. to a given altitude range. Indeed, the efficiency of an engine is optimal when the pressure of the ejected gases corresponds to the ambient pressure. However, when a rocket engine is used, it is most often a question of moving

Electrification of nozzle in a liquid rocket engine

Combustion, Explosion, and Shock Waves, 1995
A method of electrical-physical diagnostics is developed and experimental studies are conducted of the process of nozzle electrification in a liquid rocket engine operating on a hydrocarbon fuel. The highest electric potential is shown to be realized at about a stoichiometric ratio of the components, i.e., when the flow velocity, temperature, and ...
