Unimech Aerospace, in partnership with Dheya Engineering Technologies Private Limited, has developed a working prototype of the DET-500, a 500N-class micro turbojet engine. This engine is designed for use in drones, loitering munitions, and other defense platforms.
The project encompasses end-to-end manufacturing, including design for manufacturing (DFM), precision 5-axis machining, temperature-controlled assembly, and dynamic balancing at 35,000 RPM. Components are machined from Ti-6Al-4V, Inconel 625, SS316L, and Al 6061 to a tolerance of ±5 µm, with verification through coordinate measuring machines (CMM) and Pi-Web systems. Final assembly and precision sheet-metal fabrication are conducted in controlled clean-room conditions to ensure performance under extreme operational conditions.
The companies also offer support for certification processes, including collaboration with the Centre for Military Airworthiness and Certification (CEMILAC), a regulatory body under the Defence Research and Development Organisation (DRDO) responsible for the airworthiness certification of military aircraft, helicopters, unmanned aerial systems (UAS), aero-engines, and other airborne stores in India.
Unimech Aerospace and Dheya Engineering Technologies Private Limited collaborate in the design, analysis, and manufacturing of aerospace and defense systems. The companies focus on developing high-speed engine solutions and related technologies for defense applications in India.
