LF Technologies has designed a fully electric test bench for rocket engines, combining the generation of complex movements, air/water pressurization management, and onboard data acquisition. This is a custom-built, precise, and ergonomic solution designed to meet the demands of the aerospace industry.
As part of the development of a rocket engine, the customer wanted a comprehensive, flexible, and high-performance test bench to conduct mechanical and pressurization tests under various conditions.
Design and construction of a custom-built rocket engine test stand, incorporating a 100% electric solution for generating complex movements (tilting, oscillation, compression) and a controlled air/water pressurization system. This rocket engine test bench combines precision, repeatability, and ergonomics to meet the demands of the aerospace industry.
The tests involve generating complex movements (tilting, oscillation, compression), which must follow very precise position profiles and be perfectly synchronized.
Traditionally, these rocket engine test benches use hydraulic cylinders, a proven technology, but one in which achieving precise positional synchronization remains challenging, particularly for complex and repeatable movements, as is the case here.
We have developed an innovative solution based on electric actuators, offering superior positioning accuracy, native synchronization, and precise motion control.
In addition, the rocket engine test stand incorporates a pressure management system (air/water) and an on-board data acquisition system, and complies with the safety requirements of the DESP Directive.
LF Technologies has designed a custom test bench that includes:
Thanks to a turning device, the operator can easily secure the test specimen to the fixtures before inserting it into the test chamber.
The clamping is precise, with seals ensuring a tight seal.
The workpiece is loaded at an ergonomic height, the lid closes using a power-assisted closure system, and sensors automatically verify that it is properly closed before pressurization.
Air/water filling, automatic bleed, and controlled pressurization via high-pressure and low-pressure circuits. A high-precision sensor detects even the slightest leak.
The LabVIEW control software allows you to:
Thanks to this next-generation rocket engine test stand, aerospace manufacturers benefit from:
A rocket engine is a motor that generates the thrust needed to launch and control a rocket by expelling gases at high speed.
