System for airborne launch of an aircraft from a larger carrier aircraft
A system for launching, refuelling and recovering in flight an aircraft ( 10 ) such as an unmanned aerial vehicle (UAV) from a larger carrier aircraft ( 16 ) comprising a holder ( 22 ) on the carrier aircraft ( 16 ) to which the UAV ( 10 ) is detachably connectable and an extendable and retractable refuelling device ( 23, 24 ) on the carrier aircraft ( 16 ) detachably connectable to the UAV ( 10 ) whereby to launch the UAV it is disconnected from the holder ( 22 ), the refuelling device ( 23, 24 ) is extended with the UAV connected thereto to cause the UAV to trail behind the carrier aircraft and the UAV is then disconnected from the refuelling device.
1. A system for the airborne launch refuelling and recovery of an aircraft from/by a larger carrier aircraft and for refuelling and recovering the aircraft, the system comprising a holder on the carrier aircraft to which the aircraft is detachably connectable, and an extendible and retractable refuelling device mounted on or in the holder detachably connectable to the aircraft, whereby to launch the aircraft the aircraft is disconnected from the holder and the refuelling device is extended with the aircraft detachably connected thereto to cause the aircraft to trail behind the carrier aircraft and the refuelling device is disconnected from the trailing aircraft, the system enabling the aircraft to be refuelled in flight by connecting the aircraft in flight to the extended refuelling device and passing fuel from the carrier aircraft to the aircraft through the refuelling device, the aircraft also being recoverable by connecting the aircraft in flight to the extended refuelling device, retracting the refuelling device with the aircraft connected thereto and reconnecting the aircraft to the carrier aircraft.
2. A system according to claim 1 in which the refuelling device is in the form of a hose having means thereon for connection to the aircraft.
3. A system according to claim 2 in which the means on the hose is in the form of a drogue.
4. A system according to claim 3 in which the hose is wound on a drum, the drum being rotatable to enable the hose to unwind therefrom to extend the refuelling device.
5. A system according to claim 1 in which the holder has at least one latching device thereon for detachably connecting the aircraft to the holder.
6. A system according to claim 1 in which part of the carrier aircraft adjacent the holder has a latching device thereon for detachably connecting the aircraft to the carrier aircraft.
7. A system according to claim 4 in which a drive unit is provided for operating the drum and/or the or each latching device on the holder.
8. A system according to claim 1 in which a latching device is provided for detachably connecting the aircraft to the refuelling device.
9. A system according to claim 1 in which the holder is detachably connectable to the carrier aircraft.
10. A system according to claim 1 in which the aircraft is an unmanned aerial vehicle.
11. A system according to claim 2 in which the hose is wound on a drum, the drum being rotatable to enable the hose to unwind therefrom to extend the refueling device.
