The R&D and Engineering Division of Bet Shemesh Engines Ltd. (BSEL) designs gas turbine engines, modules and parts, taking advantage of the most advanced manufacturing technologies. BSEL offers development, customization and manufacture of a wide range of gas turbine engines, with engines in the 150 to 1200 lb. thrust range already in service.


In addition to expertise in jet/turbo engines, the division has over five decades of development and engineering know-how and experience in diverse engineering disciplines and technologies. Approximately 30-full time engineers boast a wide array of experience, skills, and specialties. Our team responds quickly to development challenges and provides ongoing support to BSEL’s activities in both the Engines Sector and the Engines Parts Sector, troubleshooting, introduction of new technologies, etc.


BSEL’s R&D Division may also provide general technical support and services in various engineering fields: design, integration support and customization for specific applications. Prototype and serial production are supported by the full range of BSEL’s in-house capabilities including the BSEL Rapid Prototype Center, test-cells, Machining facilities and capabilities, MRO services and more.
