The near region hindrance warning system comprises one or more of the following combination of sensors in the form of Ultrasound sensors, Ultra-short pulse lasers, Laser range finder, 1D-Radar, 2D-Radar These sensors are adapted to the outside of the aircraft and its data can be utilised by a computer system. The sensors may also be adapted to blade tips of main rotors or inserted in the outer side of aircraft.

Description

Problembeschreibung:Problem Description:

Beim Einsatz militärischer, paramilitärischer sowie Rettungs- und Polizeihubschrauber sind Landungen auf wenig oder nicht erkundeten Landeplätzen ein übliches Verfahren. Genauso wie das Operieren in engen Räumen (confined areas) um bei militärischen Einsätzen die natürliche Geländebedeckung als Schutz vor Aufklärung zu nutzen.At the Use of military, paramilitary as well Rescue and police helicopters are landings on little or unexplored landings a common one Method. Just like operating in confined areas military inserts The natural Terrain coverage as Protection against enlightenment to use.

Aufgrund der nicht vorhandenen Sicht nach hinten kommt es ausschließlich auf das Gedächtnis, die Erfahrung und das Gefühl des Piloten an, die räumlichen Verhältnisse schnell zu erfassen, sich einzuprägen und die Abstände richtig einzuschätzen. um eine Berührung mit einem Hindernis zu vermeiden.by virtue of the non-existent view to the rear it comes exclusively on the memory that Experience and feeling of the pilot, the spatial conditions to capture quickly, to memorize and the distances correctly assess. around a touch to avoid with an obstacle.

Auch bei sorgfältigster Vorbereitung der Landung und höchster Aufmerksamkeit sind optische Täuschungen über Geländeunebenheiten sowie das Auftreten von „Brown out" und „white out" nicht zu verhindern.Also most carefully Preparation of the landing and highest Attention are optical illusions about terrain bumps as well as the occurrence of "Brown out "and" white out "not to prevent.

Beim „Brown out" und „White out" wird die Sicht des Pilot durch aufgewirbelten Staub bzw. Schnee so stark beeinträchtigt, dass er den Boden in der Landephase bis zum Aufsetzen nicht mehr erkennen kann.When "Brown out "and" White out "will be the view of the pilot affected by dust or snow that he will no longer land in the landing phase until touchdown can recognize.

Bislang verfügen die Piloten über keine Hilfsmittel die sie in dieser gefährlichen Flugphase unterstützen und vor einer Hindernisberührung zu warnen.So far feature the pilots over no aids to assist you in this dangerous flight phase and before an obstacle touch to warn.

Auch für besondere Flugmanöver wie den Formationsflug gibt es keine Hilfsmittel die dem Piloten den Abstand zu anderen Luftfahrzeugen in der Formation mitteilen. Dies gilt auch für den Tiefstflug bei dem es leicht, bedingt durch optische Täuschungen zu Bodenberührungen kommen kann.Also for special maneuvers like the formation flight, there are no aids to the pilot communicate the distance to other aircraft in the formation. This also applies to the downslope at which it is light, due to optical illusions to the ground touch can come.

Lösungsbeschreibung:Solution Description:

Durch das Anbringen von Nahbereichssensoren kann die Umgebung das Luftfahrzeuges erfasst werden und Hindernisse über ein Display im Cockpit dargestellt werden.By Attaching proximity sensors may affect the environment of the aircraft be captured and obstacles over a display will be presented in the cockpit.

Als Sensoren sind geeignet und können je nach Bedarf (Kosten/Leistung/Gewicht/sonstige Aspekte) verwendet und kombiniert werden:

  • – Ultraschallsensoren
  • – Ultrakurzpulslaser
  • – Laser Range Finder
  • – 1D-Radar
  • – 2D-Radar
As sensors are suitable and can be used and combined as needed (cost / performance / weight / other aspects):
  • - Ultrasonic sensors
  • - ultrashort pulse laser
  • - Laser Range Finder
  • - 1D radar
  • - 2D radar

Die Sensoren werden je nach Bedarf (Vollschutz, Teilschutz) an der Außenseite des Luftfahrzeuges angebracht, so dass sie den Boden unter dem Luftfahrzeug abtasten und somit ein Hindernis-/Höhenprofil des Landeplatzes erfassen. Sowie mit Blick nach vorne, hinten und seitlich, so dass auch die Umgebung des Luftfahrzeuges erfasst wird und Hindernisse rechtzeitig erkannt werden. Die Sensoren können auch in/an den Blattspitzen des Hauptrotors angebracht werden, so dass sie die maximale Reichweite haben und auch für den Formationsflug besonders eingesetzt werden können.The Sensors are fitted as needed (full protection, partial protection) on the outside attached to the aircraft so that it covers the ground below the aircraft scan and thus an obstacle / height profile of the landing field to capture. As well as looking forward, back and sideways, so too the environment of the aircraft is captured and obstacles in time be recognized. The sensors can also be mounted in / at the blade tips of the main rotor, so that they have the maximum range and also for the formation flight can be used especially.

Die Sensorendaten werden über Rechner erfasst und ausgewertet und auf einem Display im Cockpit dargestellt.The Sensor data is transferred via Calculator recorded and evaluated and on a display in the cockpit shown.

Im Display wird der Umriss des Luftfahrzeuges in der Seitenansicht gezeigt und auftretende Hindernisse durch farbige Balken vor, unter oder hinter dem Luftfahrzeug dargestellt. Die Farbe der Balken und deren Position ändert sich im gleichen Verhältnis wie sich das Luftfahrzeug dem Hindernis nähert. Die Balken können auch mehrfach geteilt sein, so dass zum Beispiel eine Bodenkontur unter dem Luftfahrzeug oder die Höhe eines Hindernis vor oder hinter dem Luftfahrzeug erkennbar wird.in the Display is the outline of the aircraft in the side view shown and occurring obstacles by colored bars in front, below or behind the aircraft. The color of the bars and whose position changes in the same proportion as the aircraft approaches the obstacle. The bars can too be shared several times, so that, for example, a bottom contour below the aircraft or the altitude an obstacle in front of or behind the aircraft.

Im Display wird auch die Draufsicht auf das Luftfahrzeug dargestellt um in gleicher Weise wie oben beschrieben die Hindernisse nach vorne und hinten, sowie seitlich darzustellen. Ebenfalls ist eine 2-dimensionale Darstellung des Bodens in dieser Ansicht möglich. In dieser Darstellung wird die Höhenstruktur des Untergrundes farblich wiedergegeben.in the Display also shows the top view of the aircraft in the same way as described above, the obstacles forward and behind, as well as to represent laterally. Also is a 2-dimensional Representation of the soil in this view possible. In this presentation becomes the height structure the background color.

Für den Formationsflug und den Tiefstflug kann die Reichweite der Sensoren durch das Auswerteprogramm künstlich reduziert werden, bzw. nicht benötigte Sensoren können abgeschaltet werden.For the formation flight And the range of the sensors can be used by the evaluation program artificially be reduced or not needed Sensors can be switched off.
