DE102011111764A1 - Automatic landing device for landing e.g. aircraft on aircraft carrier, has extendable and hinged device extending arresting cable directly on equal height of hooks of aircraft to be landed, where cable is hooked in hooks up to height - Google Patents

Abstract

The device has an extendable and hinged device extending an arresting cable directly on an equal height of arrestor hooks of an aircraft to be landed. The arresting cable is hooked in the arrestor hooks up to a height of approximately 1.50 m. The arresting cable is stably held over guide rollers, fork arms, and support rods and/or on frames. The frames are mechanically, hydraulically lifted and driven with the arresting cable. A retention device of the arresting cable is movably attached on a trapezoid to raise the retention device to arrestor hook height.

Description

State of the art for fighter jets

A landing on an aircraft carrier is referred to by the pilot as a controlled crash and is therefore considered to be the most difficult maneuver in flight operations on an aircraft carrier.

The landing on an aircraft carrier takes place by the pilot being shown a gliding angle for landing by radio beams from the aircraft carrier. The National Signal Officer continues to display the vertical approach angle of the fighter jet to the pilot with an optical display.

In calm water, in good visibility, in optimal conditions, such a landing without major problems feasible. However, even in waves, where the height of the runway is constantly changing, this landing becomes a difficult maneuver, as the pilot must always re-estimate and correct the altitude. With such a condition a missing of the 4 Landeseile is possible.

Therefore, the engines of the jet fighters are set to full thrust during landing approach to allow a start when missing the safety ropes. If there is a problem, the fighter jet inevitably crashes into the sea and is a total loss.

The task is to find a way to land "unmanned aerial vehicles" "drones" on aircraft carriers, thereby enabling drones to be deployed on aircraft carriers. At the same time, the system should also be used for conventional fighter jets, even in severe conditions such. As high waves, gusts, poor visibility at night landing, etc., or to allow for engine problems a safe landing on an aircraft carrier. The components of the existing land system should not be changed.

With the features mentioned in the protection claim 1 this condition is met.

Since the solution shown for drones, aircraft and fighter jets have the same procedure, they are referred to below as a missile

State of the art for drones

A landing of unmanned aerial vehicles "drones" is on aircraft carriers z. Z. not possible. Thus, the use of drones from aircraft carriers is not possible.

In 2000, the US Navy commissioned the development of a stealth drone for long-haul flights as part of the Unmanned Combat Air Systems program. With the X-47B, this version takes shape step by step in the following years. The unmanned Steal th aircraft can be refueled in the air and should be able to land remotely on an aircraft carrier after its final completion.

Description:

The novelty is that not the fishing hook must meet the safety rope, but that the safety rope is latched into the fishing hook, even if the aircraft to be landed nor a Anflughöhe of z. B. 1 m over Landedeck has.

The core consists of a z. B. trapezoidal crumbs, hereinafter referred to as a trapezium (see drawing 1), about which z. B. the 4th catch rope is held by means of guide rollers. With fork-shaped brackets while the fishing rope is held stable on this trapeze. (please refer ) This gives the safety rope the same characteristics as the safety ropes on the flight deck. By straightening the trapeze can. The safety rope is thus erected in any height. This corresponds to a height-adjustable 2nd catch level on the landing deck.

When approaching the missile z. B. with radar, laser, etc. with bearing the height of the missile in relation to the landing deck determined. By computer can be calculated with it, up to which height the trapezoid must be erected. It should swing up to an optimal distance to the chassis so that the chassis can fly over the landing rope without touching. In the case of height fluctuations of the ship or missile or both, the constant distance between the landing deck and the missile is always maintained by changing the trapezoidal height. Also, in this electronic control by inclusion of other systems, eg. As wind gauges on the landing deck, etc. the expected approach altitude of the missile are calculated in advance. ( If the landing gear has flown over the trapeze from the missile, the trapeze is immediately raised to the catch hook height. Thus, the fishing hook can be in the Hook in the safety rope. This control also takes place by bearing and calculation by computer. ( and )

Afterwards, the aircraft is braked to a standstill with safety ropes as it is every time you land. The height of the trapeze is always changed equal to the altitude of the missile down. ( + 4 and ))

When landed, the safety rope can be withdrawn after disengaging the catch hook, whereby the rope is then automatically reinserted into the guide rollers of the trapeze. Thus, the harness is immediately available for further landings. ( and )

With the innovation is achieved by that in special conditions, where z. B. in the case of heavy waves, the height between the landing aircraft and the landing deck on the aircraft carrier constantly changed, a meeting of the safety rope is guaranteed with the fishing hooks.

Benefit for drones

The use of this important, and in importance increasing aircraft is thus made possible on aircraft carriers. The effective and material benefits can only be determined by the appropriate staff.

Benefits for z. Z. used fighter jets

The material benefit is to prevent the crash of landing jets on US aircraft carriers.

It also prevents problems with starting z. As engine damage, etc., a total loss caused by the watering of the fighter jet.

Material benefit is:

• - about 57 million US dollars per prevented crash
• - another 100 million US dollars if the falling aircraft on the flight deck damaged fighter jets and caused their total loss.
• - Rescue fighter pilots
• - Rescuing human lives on aircraft carriers

further benefits:

Another benefit is that it allows for safe landing on the aircraft carrier during nighttime landings, heavy swells, damaged aircraft, engine problems, injured pilots, fuel shortages, etc.

Another not to be underestimated advantage is that the strong nervous stress of the pilots when landing on an aircraft carrier is largely avoided, allowing pilots to focus more on other combat tasks.

In addition, the combat readiness of aircraft carriers is increased, since after a crash, a ditching, etc., the air traffic is significantly reduced.

Even with a forced landing of all fighter jets a much higher security is generated by being landed continuously, as a start-through is largely avoided
