Automatic propeller landing flight life saving device

Abstract

The invention discloses a portal low-altitude flight life saving device, and particularly relates to field of low-altitude aviation flight and life saving technologies. In the processes of electrical power line installation, bridge construction and real estate building construction, high-altitude falling casualty accidents continuously happen to constructors, and besides, people feel helpless in self-saving when trapped in a fire of a tall building and in an earthquake disaster. The automatic propeller type life saving device is a light life saving device designed according to the principles of air resistance and dynamics. Gravitational acceleration is a factor harming lives of people in falling in the air, and the end speed can be up to 52.8m / s, but the safety landing speed of people is 6.1m / s. When the life saving device descends with a human body, a propeller with a slight elevation rotates fast, a propeller angel adjuster acts periodically, so that a rotation windward-side angle generates a lift force in the reverse direction, and the cycle is carried out sequentially and endlessly to enable the end speed to decrease to 2-5.8m / s. The he automatic propeller landing flight life saving device has the main purposes of serving as a protection device for safety self-saving in the construction of high towers, bridges and high-rise buildings, and being used as a standby life saving device for military and civil aeration.

Description

technical field [0001] The invention relates to the technical field of automatic lifesaving for high-altitude, low-altitude and ultra-low-altitude operations. Background technique [0002] As we all know, in the history of aviation development for nearly a hundred years, people have always used parachutes as a life-saving tool in air distress, whether they are civil aviation pilots or airborne troops of the airborne troops. The traditional parachute has an obvious disadvantage. The speed is too slow and the space occupied by the parachute is too large, resulting in a life-saving blind spot in the range of low and ultra-low altitudes; although in recent years some people have proposed using rockets or fuel engines to make small aircraft to achieve life-saving, but this life-saving device It will produce the disadvantages of needing backup fuel and overly complicated mechanical failures, which will lead to secondary life-saving problems. With the development of society, scien...
