The present disclosure relates to a parachute rescue systems for manned and unmanned aerial vehicles.
Despite constantly improved quality of aerial vehicle and increased air safety, breakdowns and accidents can occur again and again. It is becoming increasingly important to return the damaged aerial vehicle safely to the earth. First and foremost is the rescue of human life. Rescue systems are currently installed in ultralight aircraft. For quite some time, however, it has also been possible to equip airplanes having a take-off mass larger than 450 kg with a parachute rescue system similar to ultra-light aircraft which lowers the entire airplane to the ground without harm to the occupants. In the case of engine failure, non-controllability and/or a collision over difficult terrain, the parachute is a significant safety factor and possibly the only solution to air rescue. There are already many examples of successful “landings” using parachute rescue systems for aerial vehicle.
Unfortunately, these rescue systems are mainly associated with pyrotechnic systems (rockets), which are launched when the rescue is activated, pulling the parachute from a package or container, which in turn is attached to the aerial vehicle. Manned and unmanned aerial vehicle are thus practically out and about primed with a rocket. The launch of the rocket is associated with a jet of fire, which can also damage the sensitive parachute cap. The same applies to chemical fuels. Even after a flight accident, the relief and rescue workers constantly have problems defusing the pyrotechnics not activated during the rescue to avoid getting themselves into danger.
The object of the invention is to find an intelligent parachute rescue system for manned and unmanned aerial vehicle without the use of pyrotechnic propellants. The object is achieved according to the invention as described in the claims.
An intelligent parachute rescue system for manned and unmanned aerial vehicle was developed in such a way that
In addition, a data logger can be used for the measurement data capture of flight and engine data in order to optimally control the deployment of the emergency parachute. This data logger system having switching outputs is advantageously connected to a control valve between parachute container and compressed air cylinder.
The system according to the invention is preferably used wherever parachute rescue systems are applied by means of pyrotechnic or chemical motors and/or propellants.
Technical functionalities and parameters:
An exemplary embodiment is described in the following with reference to the figures.
The figures show:
A method for operating an intelligent parachute rescue system is based on the use of compressed air to deploy an emergency parachute 3 for an aerial vehicle 14.
A possible, additional data logger (
In the case of danger, the system (
The control valve 5a can therefore advantageously also be referred to in the embodiment as an electronic control valve, which is directly connected electrically to the manual release 16 or the switching outputs of the data logger 15. The compacted compressed air in the pressure cylinder (
A container hood 1, which is not fixedly connected to the parachute container 77, advantageously made of light plastic material, closes the parachute container 77 with an internal rescue capsule 20.
When the system is activated, (
The parachute container 77, which houses the emergency parachute 3, can be designed in several variants:
A safe and compact transport away from the damaged aerial vehicle is provided in both cases. This precludes jamming when deploying the rescue capsules.
The central cord 2a, which is fastened to the emergency parachute 3 and the wire ropes of the aerial vehicle, is freely positioned on the system under the container section (
