MULTI-ROTOR HIGH PERFORMANCE DESCENT METHOD AND SYSTEM

Abstract:

A high-performance descent system for a multi-rotor aircraft includes a flight control computer comprising a processor, a propulsion system communicatively coupled to the flight control computer and configured to allow a direction of thrust relative to a vertical z-axis to be selected by the flight control computer. The processor is operable to implement a method including preparing the multi-rotor aircraft for a high-performance descent, instructing, via a flight control system, a proprotor to reduce an amount of vertical thrust produced by the proprotor by tilting the proprotor away from a vertical axis, and reducing an altitude of the multi-rotor aircraft.
