Arya News - The approach is straightforward — swap out some metal components for high-temperature polymer composites, then add homegrown electronic fuel injection.
Key features:If the claimed cost and reliability gains hold at scale, cheaper, lighter powerplants could mean more payload, longer range — and far wider adoption.

The approach is straightforward — swap out some metal components for high-temperature polymer composites, then add homegrown electronic fuel injection.
Key features:
Hybrid construction uses injection molding and printing for less-loaded parts, while highly loaded components remain metal
Developers say the engine"s cost share can drop from 30–40% to under 15%, potentially cutting total UAV production costs by ~15–25%
The electronic fuel injection system integrates with the flight controller, saving 10–40% fuel depending on mode
If the claimed cost and reliability gains hold at scale, cheaper, lighter powerplants could mean more payload, longer range — and far wider adoption.
