Energy generating system

In a fuel supply system for a space missile or a spacecraft in which the thrusters are supplied with liquid or gaseous fuel from a fuel tank in which the tank pressure decreases continuously during the operational life of the system, the fuel throughput and thus the thrust of the respective thruster or thrusters is maintained substantially constant by the arrangement of a constant flow device in the fuel line between the tank and the reaction chamber of the system. The constant flow device is a self regulating pressure loss device realized by increasing or decreasing the through-flow area of the device in response to changing fuel supply pressures.

Constant fuel supply device for a thruster

A hot gas engine operating with a Stirling cycle includes a cylindrical space filled with a process gas and containing one or two working pistons and one or two displacement pistons moveable longitudinally in relation to each other. The displacement piston or pistons are integrated with the respective regenerator. The working and displacement piston or pistons are associated with transmission gears constructed as thrust crank transmissions so as to convert rotary motion into longitudinal piston displacement motion and vice-versa.
