PulCheR (Pulsed Chemical Rocket with Green High Performance Propellants) is a three-year research project co-funded by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement n°313271. The project is mainly aimed at demonstrating the feasibility of a propulsion system that uses propellants injected in the combustion pressure at low pressure and exploits the unsteady dynamics of the pulse mode to let the pressure inside the chamber increase more than the feeding one and the chamber temperature exceed the adiabatic constant pressure combustion temperature as effect of the quasi-constant volume reaction. During the project particular attention has been focused on “green” propellants. The project is currently in its last year and it is yielding many discoveries, such as the non hypergolicity of 98% HTP and propyne. Other discoveries are expected for the last part of the third year project, when the PulCheR monopropellant thruster will work for the first time and the new bipropellant thruster with HTP and propyne will be tested together with the new combustion chamber made of high temperature resistance materials.

Abstract
PulCheR (Pulsed Chemical Rocket with Green High Performance Propellants) is a three-year research project co-funded by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement n°313271. The project is mainly aimed at demonstrating the feasibility of a propulsion system that uses propellants injected in the combustion pressure at low pressure and exploits the unsteady dynamics of the pulse mode to let the pressure inside the chamber increase more than the feeding one and the chamber temperature exceed the adiabatic constant pressure combustion temperature as effect of the quasi-constant volume reaction. During the project particular attention has been focused on “green” propellants. The project is currently in its last year and it is yielding many discoveries, such as the non hypergolicity of 98% HTP and propyne. Other discoveries are expected for the last part of the third year project, when the PulCheR monopropellant thruster will work for the first time and the new bipropellant thruster with HTP and propyne will be tested together with the new combustion chamber made of high temperature resistance materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
