摘要:
An aircraft capable of thrust-borne flight can be automatically retrieved, serviced, and launched using equipment suitable for use on a small vessel, or a base with similarly limited space or irregular motion. For retrieval, the aircraft drops a weighted cable (2,3), and pulls it at low relative speed into a broad aperture ( l a ,¨ a ) of a base apparatus (5). Continued translation of the aircraft may pull the cable clear of the apparatus, in which case it can continue in free flight and return for another retrieval attempt. Alternatively, the cable will be dragged along guiding surfaces (4) of the apparatus into and through a slot (6) or similar channel, until its free end is captured. The aircraft, having thus become anchored to the base station, is then pulled down by the cable into a receptacle (9). Guiding surfaces of the receptacle adjust the position and orientation of a probe (8) on the aircraft, while directing the probe to mate with a docking fixture. Once mated to the fixture, the cable can be released and stored aboard the aircraft; the aircraft can be automatically shut down; and fueling or other servicing can be completed through appropriate connectors in the docking fixture. The aircraft can remain docked as needed, and when desired, be automatically started and tested in preparation for launch. It can then be released into free flight. A full ground-handling cycle can thus accomplished with simple and economical apparatus. It can be used with low risk of damage, and only moderate piloting accuracy.

摘要:
The present invention relates to an aircraft (10) with a surveillance system (30) characterised in that the direction of flight towards a target is achievable by shifting the centre of gravity of the vehicle towards the target. The centre of gravity is shifted towards the target by pointing the surveillance system at the target.

Le dispositif d'aide à l'appontage d'un aéronef (10), l'aéronef étant contrôlé à distance à partir d'une station mobile, appelée navire (11), comprend des moyens de réception de données provenant de l'aéronef, notamment des attitudes de l'aéronef, l'aéronef étant en vol stationnaire prêt à apponter, la décision d'appontage devant être prise sous certaines conditions devant être réunies, le dispositif comprenant un calculateur permettant de délivrer des indicateurs temporels indiquant que les conditions sont réunies. Le dispositif comprend une jauge temporelle comprenant une graduation temporelle indiquant des zones graphiques mobiles (2) représentant les périodes pendant lesquelles les conditions sont réunies pour autoriser un appontage.
摘要:
An apparatus for converting a manned aircraft for unmanned flight, the aircraft including at least one pilot control (1030) capable of manipulation to affect operation of the aircraft, the apparatus comprising a first actuator (1006) and a second actuator (1008) each configured to selectively provide movement or resistance to movement in a first manner including linear or rotational motion, a first clutch (1012) and a second clutch (1016) each configured to selectively couple movement of the associated actuator to the pilot control, and a vehicle controller capable of being selectively enabled to operate the pilot control actuators and clutches providing unmanned operation of the aircraft or disabled providing manned operation of the aircraft. The first actuator has a first scope describing a first amount of allowable movement (1062, 1042), while the second actuator has a second scope (1068, 1040) larger than the first scope.
摘要:
An unmanned helicopter 20 includes altitude control device for giving a command of a collective pitch blade angle based on an altitude change rate command, etc., and performing altitude control of an airframe. The unmanned helicopter further includes descending device for causing the airframe to descend to a second altitude while changing descent rate command of the altitude control device and giving a descent rate command smaller than the descent rate command to the second altitude to the altitude control device for causing the airframe to descend from the second altitude to the ground.
摘要:
An unmanned rotor carried aerial vehicle comprises a propulsion unit (5) and a carrier (7) suspended from the propulsion unit. The propulsion unit (5) is connected to the carrier (7) via a cardan-like joint (9) for permitting limited tilting of the propulsion unit relative to the carrier in two orthogonal directions corresponding to the roll and pitch directions of the vehicle and for preventing relative movement between the propulsion unit and the carrier in the yaw direction of the vehicle.
