Abstract

Coupling devices for different landing gears of aircraft are disclosed. In one embodiment, a coupling device for coupling to a landing gear of an aircraft may include a first landing gear adapter that is designed for coupling to a landing gear of an aircraft of a first type. A second landing gear adapter that is designed for coupling to a landing gear of an aircraft of a second type is provided. The second type is different from the first type. A change device is coupled to the first and second landing gear adapters and designed such that optionally the first or the second landing gear adapter can be positioned in an operating position, or location of the coupling device, suitable for coupling to the landing gear. A plurality of second landing gear adapters may be provided and may one at a time be moved into the operating position in a pivoting manner.

Claims

1. A coupling device for coupling to different types of aircraft landing gears, the coupling device comprising

a first landing gear adapter (60A) configured for coupling to a first type of landing gear of an aircraft of a first type and coupled to a first pivot apparatus configured to pivot the first landing gear adapter from a magazine position thereof into an operating position;

a second landing gear adapter (60B) configured for coupling to a second type of landing gear of an aircraft of a second type, different from the first type and coupled to a second pivot apparatus configured to pivot the second landing gear adapter from a magazine position thereof into the operating position;

a changeover device (30) comprising the first pivot apparatus and the second pivot apparatus and thereby coupled to the first and the second landing gear adapter (60A, 60B), whereby selectively the first (60A) or the second landing gear adapter (60B) is positionable in the operating position that is suitable for coupling the positioned landing gear adapter to the landing gear of each of the first and second aircraft types for mechanically loadable towing of said aircraft.

2. The coupling device according to claim 1, comprising a third landing gear adapter (60C) for coupling to a third type of landing gear of an aircraft of a third type, different from the first and the second type, wherein the changeover device (30) is coupled to the third landing gear adapter and configured to selectively position the first, the second or the third landing gear adapter mechanically loadable at the operating position for a thrust or tensile load of at least 1000 kg.

3. The coupling device according to claim 1 or 2, wherein an individual adapter socket (70A, 70B) couples the changeover device (30) to each landing gear adapter.

4. The coupling device according to claim 1, wherein a positioning apparatus (50) mechanically positions one of the landing gear adapters in the operating position at a time.

5. The coupling device according to claim 4, wherein the positioning apparatus (50) mechanically positions one of the landing gear adapter in the operating position at a time, and wherein the mechanically stable positioning couples each of the adapter sockets to the positioning apparatus (50) at a time.

6. The coupling device according to claim 5, wherein the positioning apparatus (50) comprises a bolt tongue (52) engaging one adapter socket (70, 70B) in the operating position (61) and locking this position by a bolt (51).

7. The coupling device according to claim 1, further comprising a securing apparatus (40) holding each landing gear adapter in a magazine position thereof in a mechanically secured manner.

8. The coupling device according to claim 1, wherein the operating position is at a bolt tongue (52).

9. The coupling device according to claim 1, wherein the coupling device is mounted mechanically reversibly on a tow bar device (110).

10. The coupling device according to claim 1, wherein the coupling device is mounted mechanically reversibly (112) on a towing vehicle (150).

11. The coupling device according to claim 1 which comprises two bearing apparatuses configured to allow tilting of each landing gear adapter from the magazine position thereof into the single operating position on a bolt tongue (52).

12. The coupling device according to claim 1, wherein the pivot apparatuses (90A, 90B) are arranged such that a pivot plane of each pivot apparatus intersects with a right or left edge of the operating portion (52).

13. The coupling device according to claim 1, wherein the pivot apparatuses (90A, 90B) are arranged on two opposing sides of the changeover device (30).

14. The coupling device according to claim 1, wherein each landing gear adapter (60A, 60B) is fitted to a corresponding adapter socket (70A, 70B) in an inclined manner.

15. A towing device for ground movements of aircraft of technically different types, wherein the towing device comprises a coupling device (100) according to claim 1.

16. The towing device according to claim 15 which comprises a chassis (111) and is designed for coupling to a towing vehicle.

17. A method for coupling a towing device to different types of aircraft landing gears, comprising the following steps

providing a first and at least a second landing gear adapter (60A, 60B) that are configured for coupling to a first type of landing gear for a first aircraft and for coupling to a second type of landing gear for a second aircraft, wherein the landing gear types and the two aircraft are different;

wherein the second landing gear adapter is different from the first landing gear adapter;

either the first (60A) or the second landing gear adapter (60B) is pivoted and positioned in a mechanically loadable manner in an operating position (61) and is releasable locked in this operating position suitable for coupling to the particular landing gear, wherein a positioning apparatus (50) comprises a bolt tongue (52) engaging each of the landing gear adapters (60A, 70A) in the operating position (61) and locking the operating position by a bolt (51) individually for each of the adapters.

18. The method according to claim 17, wherein either the second (60B, 70B) or the first landing gear adapter (60A, 70A) in the operating position (61) is released by unlocking and is moved back into a magazine position by being pivoted away from the operating position.

19. A coupling device for coupling to different types of aircraft landing gears, the coupling device comprising

a first landing gear adapter configured for coupling to a first type of landing gear of an aircraft of a first type
