Industries We Serve
Next-Generation Propulsion Architectures
We're developing three interconnected technology pillars focused on thermal efficiency, manufacturing repeatability, and hydrogen integration — built for real-world aerospace demands.
Thermal-Optimized BLDC / PMSM
Air-cooled SRM series electric motors built to minimize intrinsic heat generation — enabling sustained high-load duty cycles without thermal degradation.
- Power density optimized design
- Custom windings (SRM 1090 to 16040)
- Proven at 3,000 ft MSL Bengaluru
Monolithic CFRP & Manufacturing
Our pure monolithic carbon fibre construction eliminates foam cores to completely prevent delamination, moisture ingress, and structural flex under extreme operating conditions.
- Pure T800 Carbon Fibre prepreg
- >384 MPa tensile strength
- Environmental range: –40°C to 120°C
Hydrogen Fuel Cell Architecture
We design lightweight balance-of-plant solutions that package fuel cell subsystems compactly — enabling practical, highly optimized long-endurance flights.
- Integrated balance-of-plant system
- Optimized hybrid fuel cell thermal control
- Unmatched UAV flight hour multipliers
