Ukrainian company First Parsec has published a video of ground tests of the SHOOM-20 pulsating jet engine, which is being developed for its own unmanned platforms.
According to Military, during the test, the team tested improvements aimed at increasing the duration of continuous operation of the installation to two hours. The manufacturer published a video of the tests on its social networks. The developers also announced a guideline: with such a resource, the device with SHOOM-20 can cover approximately 800 km. The tests were carried out within the framework of a broader project to create the KROOK-1 strike drone and the SUETA-1 target drone.
A pulsed air-jet engine creates thrust with a series of short pulses: air enters the chamber, mixes with fuel and burns quickly, forming a thrust, after which the pressure drops and the cycle repeats many times per second. The absence of a turbine and compressor simplifies the design, but for practical application, long-term operation becomes critical. The pulse principle gives high vibrations, thermal loads and noise, so engineers have to increase the resource and stability if the engine is to operate for hours, not minutes. The report did not detail what changes were tested this time.
Previously, dev.ua wrote about how the Ukrainian company Scopa Industries has completed the ground phase of testing the new pulsed jet engine «Shepit» for drones and is moving on to the flight testing phase. The engine is assembled entirely from Ukrainian components and is designed for installation on various types of UAVs.
