The PBS TJ80-120 jet engine is a great example of the continuous development and innovation we aim for in our company. Based on its predecessor, the PBS TJ80-120 jet engine, this engine combines all of the original features together with a significant improvement of the key attributes. We increased the thrust and air mass flow while maintaining the high-quality standard of all PBS products.
The maximum measured thrust reached 1,200 N while the engine's weight went up only by 0.7 kg compared to
PBS TJ80 900 N at 12.1 kg. The possibilities of ground and in-flight start and restart and saltwater recovery remain unchanged.
Furthermore, the engine can be started rather quickly using the windmill starting option.
Also, the properties of starting and operating envelopes have not changed. The maximum altitude and speed of the starting envelope remained 6,000 m and 0.6 M, which is satisfactory for air-launched applications. The operating envelope limits stand at 10,000 m altitude and speed of 0.9 M.
