The stealth high altitude long endurance Unmanned Aerial Vehicle (UAV) is a crucial piece of equipment for the future, with its trim issue being critically important to its endurance capabilities. To meet the requirements for high stealth and extended endurance, this paper presents a preliminary comprehensive design concept for a UAV with a large swept-wing flying wing layout. An integrated method utilizing the six-degree-of-freedom (6-DOF) equations is adopted to develop a real-time trim state calculation model for the UAV. A range of control allocation functions is proposed to efficiently manage the actuation of elevators and elevons. Under the existing constraints of a special stealth configuration, and based on an optimized control surface combination strategy, the endurance performance is improved by 3.55% compared to traditional methods.

摘要

The stealth high altitude long endurance Unmanned Aerial Vehicle (UAV) is a crucial piece of equipment for the future, with its trim issue being critically important to its endurance capabilities. To meet the requirements for high stealth and extended endurance, this paper presents a preliminary comprehensive design concept for a UAV with a large swept-wing flying wing layout. An integrated method utilizing the six-degree-of-freedom (6-DOF) equations is adopted to develop a real-time trim state calculation model for the UAV. A range of control allocation functions is proposed to efficiently manage the actuation of elevators and elevons. Under the existing constraints of a special stealth configuration, and based on an optimized control surface combination strategy, the endurance performance is improved by 3.55% compared to traditional methods.
