TheAI-PBS-350is aturbojetengine jointly developed byCzechmanufacturerPBS Velká Bítešand theUkrainiandesign bureauIvchenko-Progress.The engine is marketed for use inmissilesand largeunmanned aerial systems.As of 2024, it is currently the highest thrust engine developed by PBS,[1]exceeding the thrust of PBS's next highest engine, thePBS TJ150.
History
[edit]On the 19th of June, 2023[2],Velka Bites and Ivchenko-Progress signed a memorandum of understanding, detailing the framework from which the engine would be developed and produced.[3]
Concerns were raised about Ivchenko-Progress' capability to produce the engine,[4]with its headquarters inZaporizhzhia,a city heavily affected by theRussian invasion of Ukraine.Ivor Kravchenko, the director general for Ivchenko-Progress stated that while the factory had sustained damage, it continues to operate, with strong backing from theUkrainian governmentenabling it to maintain it's 3000 strong workforce.
The engine was displayed at the 2024Farnborough International Airshow,along with other products from PBS, such asturbine engines,Auxiliary power unitsandenvironmental control systems.[5]
Design
[edit]The AI-PBS-350 is a compact turbojet engine optimized for single mission UAV systems. It features a four stage compressor, driven by a single stage turbine.[6]It has a digital engine control unit and a fuel metering pump. Along with pyrotechnic ignition, it also utilizes windmill starting, wherein the aircraft uses its forwards momentum to turn the rotor blades, reducing the weight of the system and improving performance.[7]
