摘要:
A space propulsion module in particular for equipping spacecraft such as satellites, probes, or indeed upper stages of rockets. According to the invention, this space propulsion module comprises a solid-fuel chemical thruster (10), having a main body (11), and at least one electric thruster (30), said at least one electric thruster (30) being mounted on said main body (11) of the solid-fuel chemical thruster (10).
摘要:
Moteur (10) pour engin spatial comportant un propulseur chimique comprenant une tuyère (30) pour l'éjection de gaz de combustion, ainsi qu'un propulseur à effet Hall. Le moteur est agencé de telle sorte que la tuyère sert de canal d'éjection de particules éjectées par le propulseur à effet Hall lorsque celui-ci est en fonctionnement. Le moteur peut délivrer une forte poussée avec une faible impulsion spécifique ou une poussée relativement faible avec une forte impulsion spécifique.
摘要:
A nozzleless hybrid rocket motor includes a fuel element that defines a combustion chamber therewithin, in which combustion of the fuel and an oxidizer occurs. The combustion gases produced by the combustion between the fuel and the oxidizer transition to supersonic flow before leaving the fuel element, eliminating the need for a separate nozzle. The fuel element may be a part of a structural element of a vehicle, for example being a part of a fuselage, wing, fairing, or other part of a space vehicle or an air vehicle, with the fuel element an integral and continuous part of the structural element. Combustion of part of the fuel element may allow vehicle structure to be used to provide thrust, such as for maneuver, consuming part of the structure. The fuel element may be made by an additive manufacturing process.

摘要:
This propulsion system of a rocket motor assembly includes an array of attitude-control rocket engines, one or more oxidizer-fluid sources, one or more ignition-fluid sources, and, optionally, one or more primary rocket engines. Each of the attitude-control rocket engines has a respective combustion chamber and is offset from the longitudinal axis of the rocket motor assembly so that when a selected one or group of the attitude-control rocket engines is fired, the flight path of the assembly is diverted and/or the rocket assembly spins. The oxidizer-fluid and ignition-fluid sources are in operative communication with the attitude-control rocket engines to respectively permit oxidizer fluid and ignition fluid to be supplied to selected ones or groups of the attitude-control rocket engines. Optionally, a portion of the ignition fluid from the ignition-fluid source can be cooled and used to pressurize the oxidizer-fluid source.

摘要:
The present invention relates to a method and an arrangement for, in multi-stage rockets (3) provided with a number of successively ignitable rocket engines (7, 13) arranged one in front of another in the flying direction of the rocket and joined together detachably with one another, each following rocket engine (13) in the ignition sequence depending, for its ignition, on being initiated after a preceding rocket engine (7) has been able to bun out, causing each preceding rocket engine (7) included in the ignition sequence to be jettisoned by virtue of the next engine having reached its working pressure. According to the invention, each preceding rocket engine is designed with a preferably conical guide part (11) which is directed forwards in the flying direction of the rocket and geometrically adapted to the exhaust nozzle (12) of the following rocket engine (13) and which, in the initial position, is fitted into said exhaust nozzle (12) and fixed in this position by means of at least one blocking part (15) which is deformable or capable of elastic recovery.
