Moscow Aviation Institute, in collaboration with JSC "Reshetnev", has developed an electric rocket engine simulator that allows testing and configuring the electronics of spacecraft directly on the ground without a vacuum chamber. The device is entirely composed of domestic components, making it faster, simpler, and more cost-effective than traditional testing methods.
The key feature of the simulator is its ability to accurately reproduce fast-flowing electrical processes and sharp changes in power supply parameters, up to tens of thousands of times per second. The principle of operation is based on a programmable microcontroller with algorithms created from real engine data, which allows simulating a load virtually indistinguishable from the operation of a real plasma engine.
To date, a prototype has been manufactured and successfully tested for a high-impulse dual-mode correction unit based on a stationary plasma engine developed by the "Keldysh Center". Fine-tuning and preliminary tests have been carried out, and the company "Reshetnev" is mastering the serial production of the product. Final acceptance tests are planned for 2025.
The simulator reduces the time and cost of testing spacecraft, reduces risks when checking electronics, and accelerates the development of new rocket engines. In the future, the range of simulators will be expanded and adapted to various types of plasma rocket engines.
