Fulcrum Air - heavy lift drones



The FulcrumAir E7500 is a heavy lift, Coaxial Helicopter style, battery powered RPAS that has been optimized for short to medium haul flights while carrying slung payloads up to 50kg in weight. Its exceptional thrust to weight ratio of 2.8 is made possible with the use of two 15kW brushless DC motors with forced cooling and a lightweight synchronous belt transmission system, as well as eliminating the use of cyclic pitch for altitude control. Altitude control is furnished with a quadrotor-style cluster of horizontally thrusting control motors and propellers, which in addition to pitch and roll control, provide near-instantaneous lateral and longitudinal force as required, resulting in exceptional position holding capability. The use of flapping hinges and high tensile steel and aluminum components in the rotor heads allows for main rotor tip speeds in excess of Mach 0.5, which provides a generous thrust overhead, even in hot and high conditions.
