PBS Group Develops New Jet Engine for Drones in Partnership with Ukraine's Ivchenko Progress

Czech company PBS Group, in collaboration with Ukrainian firm Ivchenko Progress, has developed the AL-PBS-350, a powerful jet engine designed specifically for unmanned aerial vehicles (UAVs).

“In cooperation with the Ukrainian company Ivchenko Progress, PBS jointly developed a new type of powerful jet engine AI-PBS-350 for unmanned aerial vehicles, which are essential for modern military operations. The supply of engines significantly improves the Ukrainian military's ability to operate with modern unmanned systems. Supporting Ukraine is one of the priorities for PBS GROUP,” the company said in an official statement.

PBS and Ukraine’s Ivchenko-Progress signed agreement to develop the AI-PBS-350 engine to power UAVs and cruise missiles in June 2023.

The AI-PBS-350 jet engine has the following declared characteristics: it delivers a maximum thrust of 3,400 N (765.76 lbf) and weighs 51 kg. The engine has an outer diameter of 298 mm and a length of 706 mm, with an electrical power output of 5.0 kW.

Looking ahead, PBS Group plans to increase jet engine production capacity by 2025, with production expected to grow by nearly 300% between 2023 and 2024. Expansion is planned for both Czech facilities and international branches in the U.S. and India.

Recently, PBS Group defended against a major cyberattack with assistance from Czech intelligence services. These attacks are believed to be part of an effort to destabilize the company’s cooperation with Ukraine. “Despite the cyber and media attacks, PBS Group remains committed to supporting Ukraine. These efforts are crucial, and we are fully capable of defending ourselves while continuing our mission,” stated PBS Group Executive Director Pavel Čechal.

PBS Group, led by its owner William Didden, recently completed a U.S. security clearance process, which included compliance checks on trade sanctions and technical abilities, due to its involvement with Lockheed Martin. Following the clearance, the company secured a U.S. government contract and is now working on technologies, such as 3D printing, for Lockheed Martin.
