What Are Unmanned Helicopters?
Helicopter drones are unmanned aircraft that operate on the same flight principles as manned helicopters, utilizing spinning rotors to generate lift and thrust. The predominant rotor configuration features a single main rotor complemented by a tail rotor to counteract torque. Alternative designs, such as tandem rotor and tilt rotor UAVs, also exist, employing rotors mounted on rotating engine pods that adjust angles to facilitate vertical lift or forward flight.
These drones can be purpose-built or adapted from existing manned platforms. Some models offer the versatility to switch between piloted and unmanned operations, earning the designation of Optionally Piloted Vehicles (OPVs). This adaptability allows for a broader range of missions and operational flexibility.
