Description

带整流装置的螺旋桨垂直起降飞行器 Propeller vertical take-off and landing aircraft with fairing

技术领域 technical field

本实用新型涉及一种螺旋桨飞行器,尤其是一种能稳定安全地垂直起降、飞行和作空中停留的带整流装置的螺旋桨垂直起降飞行器。The utility model relates to a propeller aircraft, in particular to a propeller vertical take-off and landing aircraft with a rectifying device which can stably and safely take off and land vertically, fly and stay in the air.

背景技术 Background technique

公知的螺旋桨垂直起降飞行器如直升飞机、航模(或玩具)螺旋桨飞行器等包括有机体、控制装置、动力装置和螺旋桨。控制装置、动力装置装于机体内,螺旋桨装于机体上方。这种螺旋桨垂直起降飞行器有多桨和单桨加尾舵小旋翼两种。都是靠螺旋桨转动,使螺旋桨上下表面的空气产生压力差给飞行器带来升力,再通过对飞行器每片桨叶的桨距进行控制或对飞行器尾舵小旋翼的控制来调整飞行器的飞行姿态和方向。由于螺旋桨是靠旋转的气流产生升力,这种旋转气流会产生反向的扭力,使飞行器产生左右扭摆,以至很难使飞行器稳定地垂直起降、飞行和作空中停留,对飞行器的安全构成潜在而持续的威胁,这是其缺点。Known propeller vertical take-off and landing aircraft such as helicopters, model airplanes (or toy) propeller aircraft, etc. include organisms, control devices, power units and propellers. The control device and the power unit are installed in the body, and the propeller is installed above the body. There are two types of vertical take-off and landing aircraft with multiple propellers and a small rotor with single propeller and tail rudder. All rely on the rotation of the propeller, so that the air on the upper and lower surfaces of the propeller produces a pressure difference to bring lift to the aircraft, and then adjust the flight attitude of the aircraft by controlling the pitch of each blade of the aircraft or controlling the small rotor of the tail rudder of the aircraft. direction. Since the propeller generates lift by the rotating airflow, this rotating airflow will generate reverse torsion, causing the aircraft to twist left and right, so that it is difficult to make the aircraft take off and land stably, fly and stay in the air, which poses a potential threat to the safety of the aircraft. And the constant threat, that's its downside.

发明内容 Contents of the invention

针对现有螺旋桨飞行器的缺点,本实用新型的目的在于提供这样一种带整流装置的螺旋桨垂直起降飞行器,该飞行器在起降、飞行和空中停留中不会产生左右扭摆的情况,使飞行器稳定地垂直起降、飞行和作空中停留,并可在紧急时刻可以保证飞行器某种程度的稳定状态,起到安全、节能的作用。Aiming at the shortcomings of existing propeller aircraft, the purpose of this utility model is to provide such a propeller vertical take-off and landing aircraft with a rectifying device, which will not produce left and right torsion during take-off and landing, flight and air stay, so that the aircraft is stable. It can take off and land vertically, fly and stay in the air, and can ensure a certain degree of stability of the aircraft in an emergency, playing the role of safety and energy saving.

本实用新型解决其技术问题所采用的技术方案是:包括机体、控制装置、动力装置和螺旋桨,控制装置、动力装置装于机体内,螺旋桨装于机体的上方,其特征在于:还包括有整流装置,该整流装置包括至少两片整流板,所述整流板呈平板带状,其平板的平面与飞行器螺旋轴轴向平行,即与螺旋桨旋转平面垂直,整流板相互交叉装于机体下面。The technical solution adopted by the utility model to solve its technical problems is: including the body, the control device, the power device and the propeller, the control device and the power device are installed in the body, and the propeller is installed on the top of the body, and it is characterized in that: it also includes a rectifier The rectifying device comprises at least two rectifying plates, the rectifying plates are in the shape of flat strips, and the plane of the plates is parallel to the axial direction of the aircraft screw shaft, that is, perpendicular to the plane of rotation of the propeller, and the rectifying plates are intersected and installed under the body.

本实用新型的有益效果是:使用带状整流板组成的整流装置能将螺旋桨旋转产生的大部分旋转气流垂直向下,反向扭力转化为向下的推力,使飞行器在起降、飞行和空中停留中不会产生左右扭摆的情况,能稳定地垂直起降、飞行和作空中停留;当着陆点状况较复杂,比如不水平地面或在颠簸的船上,整流板可起到降落支架的作用,从而防止飞行器不垂直于降落地面时螺旋浆击到地面;并且可以产生一定的升力,起到安全节能的作用。需要紧急降落时,整流板可使飞行器垂直下降,不至于倾斜翻滚,使得飞行器处于某种程度的稳定状态,从而大大提高紧急状况下的安全系数;整流板可以通过调整角度来起到调整飞行方向以及产生矢量推力的作用。特别是在其实施例中增加了环形翼,不但可以保护螺旋桨在飞行和停机时不至于旋击到靠近飞行器的物体,还可以防止横吹动的风直接吹到螺旋桨上影响飞行器的正常运行。The beneficial effect of the utility model is that: the rectifying device composed of strip-shaped rectifying plates can make most of the rotating air flow generated by the rotation of the propeller vertically downward, and the reverse torque can be converted into a downward thrust, so that the aircraft can take off and land, fly and fly in the air. There will be no left and right torsion during the stop, and it can take off and land stably, fly and stay in the air; when the landing point is complicated, such as uneven ground or on a turbulent ship, the rectifier can act as a landing support. In this way, the propeller is prevented from hitting the ground when the aircraft is not perpendicular to the landing ground; and a certain lift force can be generated to play a role of safety and energy saving. When an emergency landing is required, the rectifying plate can make the aircraft descend vertically without tilting and rolling, so that the aircraft is in a stable state to a certain extent, thereby greatly improving the safety factor in emergency situations; the rectifying plate can adjust the flight direction by adjusting the angle And the effect of generating vector thrust. Especially in its embodiment, the annular wing is added, which can not only protect the propeller from spinning against objects close to the aircraft during flight and shutdown, but also prevent the horizontal wind from directly blowing on the propeller to affect the normal operation of the aircraft.
