Abstract

The inflatable cushion (1) designated Hapu from the German Hubschrauber-Absturz-Puffer is attachable to the underside of the fuselage of a helicopter. The interior of the cushion is divided into a number of unfolding chambers (2).Several protective plates (4) made of aluminium or plastics are applied to the outer side of the cushion. Inflation takes place via one or more pressure medium sources (5).

Description

Hubschrauber-Absturz-Puffer (Hapu) ist eine Vorrichtung zum abpuffern des Hubschraubers beim Absturz (aufschlagen auf den Boden) mittels eines Pufferkörpers.Helicopter Crash Buffer (Hapu) is a device to buffer the helicopter in the event of a crash (open to the floor) by means of a buffer body.

Bisher zerschellte bei einem Absturz der Hubschrauber meist am Boden oder es entstand großer Schaden.So far, the helicopter mostly crashed in a crash on the ground or there was great damage.

Die Erfindung des Hapu soll das Überleben der Besatzung ermöglichen sowie Hubschrauber oder Modellhubschrauber gegen Schaden schützen.The invention of the Hapu is said to enable the crew to survive as well as helicopters or model helicopters against Protect damage.

Der Pufferkörper ist in mehrere Kammern aufgeteilt um eine größere Druckbelastung zu ermöglichen. In jeder Kammer sind Rückschlagventile angebracht, um ein zurückströmen der z. B. Gase zu verhindern und somit eine stärkere Pufferwirkung zu ermöglichen. Der Pufferkörper ist außen mit mehreren Platten versehen. Diese Platten schützen den Pufferkörper gegen Witterungseinflüsse und verhindern bei einer Notlandung ein aufschlitzen der Kammern. Der Pufferkörper wird über eine oder mehrere Druckmittelquellen (z. B. Gaspatronen) entfaltet.The buffer body is divided into several chambers by one to allow greater pressure load. In every chamber are Check valves attached to a backflow of the z. B. Prevent gases and thus a stronger buffer effect enable. The buffer body is outside with several plates Mistake. These plates protect the buffer body against the weather and prevent an emergency landing slitting the chambers. The buffer body is over a or several pressure medium sources (e.g. gas cartridges) unfolded.

Bei Gefahr betätigt der Pilot den Notknopf um entweder den Pufferkörper sofort zu entfalten oder es wird ein Sensor aktiviert (z. B. Infrarot) und der Pufferkörper wird erst ab einem bestimmten Abstand von der Erde entfaltet. Beim auftreffen des Pufferkörpers auf dem Boden wird der Hubschrauber abgefangen. Bei starkem Druck wird ein Teil der Kammern platzen wodurch die Energie abgebaut wird. Nach der Notlandung wird über die Entleerungsventile der Pufferkörper wieder entleert.In the event of danger, the pilot presses the emergency button around either the Unfold buffer body immediately or it becomes a sensor activated (e.g. infrared) and the buffer body is first unfolded from a certain distance from Earth. When the buffer body hits the floor, the Intercepted helicopter. With strong pressure, a part of the chambers burst, whereby the energy is reduced. After the emergency landing, the Buffer body emptied again.
