Key Features
Specifications (Preliminary)
- High power to weight
- Low acoustic signature
- Cowls much tighter than typical boxer twin
- 3D-printed aluminum head, cylinder, crankcase and exhaust improves engine repeatability
- Hardware, electronics and software all designed specifically for UAS applications
- Primary and secondary shaking forces are inherently balanced
- Fires every 120 deg. Higher frequency torque impulses provide for relatively smooth operation
- Separate crankcases for each cylinder for improved mixture control and decreased cycle-to-cycle variability
- Ideal for spark ignited heavy fuel due to small cylinder bores and liquid cooling
