The invention discloses a jet flow layout structure capable of being used for a flying wing layout unmanned aerial vehicle. A jet flow control area is arranged on an outer wing of a wing. The jet flow action areas are arranged in the range of 57%-86% of the span direction of the aircraft, account for 29% of the total span length, and are symmetrically arranged on the left side and the right side of the aircraft. The invention relates to a novel control technology for realizing control-surface-free flight of a flying-wing aircraft through an active flow control means, which can replace a movable control surface on a conventional aircraft and avoid the pneumatic and stealth performance loss caused by the deflection of the control surface. According to the technical scheme, the common problems that an existing flying wing layout aircraft is complex in control system, low in control surface efficiency, serious in control surface control coupling, obvious in pneumatic and stealth performance reduction caused by control surface deflection and the like are solved.
本发明公开了一种可用于飞翼布局无人飞行器的射流布局结构,射流控制区域布置在机翼外翼。射流作用区域布置在飞行器展向57%~86%范围,射流作用区域占总展长的29%,射流作用区域对称布置在飞行器左右两侧。本发明是一种通过主动流动控制手段实现飞翼布局飞行器无舵面飞行的新型操控技术,其可取代常规飞行器上的活动舵面,避免舵面偏转带来的气动、隐身性能损失,是解决当前飞翼布局飞行器控制系统复杂、舵面效率低、舵面操纵耦合严重、舵面偏转带来气动和隐身性能明显下降等共性问题新的技术方案。
