PROPULSION SYSTEM FOR VERTICAL OR SUBSTANTIALLY VERTICAL TAKEOFF AIRCRAFT

摘要

The present invention relates to a propulsion system for aircraft, comprising: • - a primary propulsion system (PI) for generating horizontal thrust needed for cruise; • - a secondary propulsion system (RAPS) for generating vertical thrust so that the aircraft is supported and/or lifted in a configuration other than the cruise one; • - a control system (RCU) intended to control the primary and secondary propulsion system. The secondary propulsion system (RAPS) comprises a plurality of additional thrust generators (RTG), in particular propellers and/or fans (100/103/104), powered by rechargeable energy storage devices RRSU). The energy storage devices (RRSU) and the secondary propulsion system (RAPS) are dimensioned so that they can lift the aircraft without other means.
