Distributed Electric Propulsion (DEP) for Combat Survivability: Tolerating Rotor Loss

Core aerospace engineering and protocols for Ballistic-Tolerant Propulsion.

The Vulnerability of Traditional Combat Helicopters

Conventional military helicopters have single points of catastrophic failure: a single machine-gun round penetrating the main transmission gearbox, tail rotor drive shaft, or swashplate results in immediate aircraft loss and crew fatality.

Resilience Through Distributed Electric Multi-Rotors

DefenseVTOL utilizes 8 to 12 independent electric rotors distributed along composite wings. If two rotors are destroyed by hostile fire, the digital fly-by-wire controller instantly redistributes torque to the surviving motors within 10 milliseconds, allowing the combat aircraft to complete its mission and land safely.

Isolated Multi-Motor Channels: Segmenting motor drive inverters across separated physical bays.
Aerodynamic Control Reconfiguration: Dynamically re-trimming remaining rotors within 10 milliseconds of motor loss.
Self-Sealing Composite Battery Armor: Preventing catastrophic fire when battery cells are pierced by bullets.
Redundant Triple-Split Flight Bus: Preserving control commands across physical airframe penetrations.
