Abstract
The aerodynamic air bag-parachute reduction system combines air bag and parachute with different aerodynamic characteristics. The aerodynamic reduction system of the present invention has aerodynamic characteristics superior to available parachute.
Description
Technical field
The present invention relates to a kind of aerodynamic braking system, particularly a kind of Pneumatic reduction system for air bag parachute.·
Background technology
Parachute has in light weight, the effective advantage of slowing down as a kind of aerodynamic braking system, has been widely used in fields such as Aeronautics and Astronautics, weapons and physical culture.Existing parachute system generally all comprises pilot-parachute, and opening fast of it opening extremely crucial effect to drogue, main chute safety hit.The pilot-parachute pattern is a lot, by its constructional feature, often is divided into three classes at present: soft band axial cord pilot-parachute, soft axial cord pilot-parachute and the spring skeleton type pilot-parachute be not with.The advantage of soft band axial cord pilot-parachute is the umbrella light weight, and simple in structure, volume is little, good manufacturability, but opening speed does not have spring skeleton pilot-parachute fast; The advantage of soft no axial cord pilot-parachute is that good stability, reliable operation, shortcoming are that complex structure, volume weight are bigger, generally is used for aerial bomb parachute and recorery parachute, or is used for the cargo parachute that not only plays stabilization but also play the pilot-parachute effect; Spring skeleton pilot-parachute advantage is that opening speed is fast, and shortcoming is that complex structure, manufacturability are poor, volume, weight are also big than corresponding soft pilot-parachute.In escape parachute is used, umbrella be can be divided into by the typical parachute-opening program of escape parachute and umbrella and power parachute-opening two classes drawn back, wherein all need pilot-parachute or drogue that escape parachute is drawn and pull out.Pilot-parachute or drogue are owing to self break down or when being in state such as human body wake zone, all the dangerous situation that parachute delay or umbrella are not opened can take place.Be in eddy zone at parachute, pilot-parachute or parachute sleeve and parachutist's limbs or equipment hook, mutual collision causes under many situations such as canopy folds between the parachutist, all major accident can take place.
For the large-scale like this aircraft of seating plane, when it is prominent in-flight when running into dangerous situation, the application that can make it the existing parachute system of safety deceleration decline is restricted, because existing parachute system is when specifically implementing to equip to this large-scale aircraft, huge, the complex structure of volume weight, and easily twine when using.
At present in the building emergency escape equipment along rope downslide system, parachute system and cylindrical shape slide, these all can not effectively be saved oneself when dangerous situation takes place fast.Because along rope downslide system for single and low-rise building use still can, many people use simultaneously or high level in use and then be restricted; Existing parachute system during personnel's emergency escape equipment, uses extremely inconvenience in as high, medium and low layer building; The cylindrical shape slide still can be used for personnel's emergency escape in the low-rise building, and the then many people of middle level and high level can occur gliding crowded and the damage of gliding when escaping, moreover this equipment implements difficulty for middle level and high level.·
Summary of the invention
The object of the present invention is to provide a kind of Aeronautics and Astronautics, weapons, physical culture and skyscraper Pneumatic reduction system for air bag parachute in field such as recover that can be widely used in.
Pneumatic reduction system for air bag parachute of the present invention comprises a gas-bag system and a umbrella system.Gas-bag system comprises one or more air bags, inflation mechanism, storage tank, gas generator.The umbrella system comprises a tool or many tools umbrella.Combination on space structure and its function can have various ways to Pneumatic reduction system for air bag parachute according to gas-bag system and umbrella system.Air bag can be used as stablizing the deceleration air bag, and with the pure gas-bag system that do not comprise the umbrella system as speed brake.
For the advantage of the aerodynamic characteristics that fully had separately in conjunction with air bag and parachute, air bag can be made the body of the proterties of proterties with umbrella or part umbrella; The body that maybe will have canopy or umbrella width of cloth proterties is centered around around the air bag.·
