AST-250 Turbojet
Astro Engine’s AST-250 Turbojet is a radial flow turbojet designed to provide thrust to small high-speed UAVs and model jet aircraft. The designated system provides ease of operation, flexibility, and maintainability over other systems. Different engine parameters can be altered via touch LCD (GSU). Astro Engines have undergone extensive redesign and testing in order to provide safe and reliable working engines with the highest quality standards for the satisfaction of customers.
All engines, before delivery, are subjected to test runs, for the said purpose, a specialized engine test bed measures and records all performance data automatically and the engine rotors are dynamically balanced and finely tuned. All manufacturing, assembly of mechanical parts and testing are performed in-house in our workshop/Laboratory. In addition to that, the Electronics Control Unit (ECU) hardware and related software are also developed, manufactured, and tested in-house
