Abstract

PURPOSE:To protect antennas from a shock at the time of departure/recovery and to load large antennas by collapsing the antennas of an antenna loading method for an unmanned aircraft, storing then in an airframe and extending and storing the antennas while flying. CONSTITUTION:An antenna storage part 2 is provided in a part of the airframe of the unmanned aircraft and the antennas 3 and 4 which can be stored by overlapping them are stored. Then, the door 9 of the antenna storage part is opened and the antennas are extended in a prescribed opening operation state. After they are operated, they are stored again when the unmanned aircraft is recovered. Two pairs of extending devices 6 having actuators 5 are fitted to one antenna 3, and developing devices 8 with actuators 7 are similarly fitted to the other antenna 4. When the antenna storage door 9 of the storage part 2 in the unmanned aircraft 1 is opened, the actuators 5 operate and one antenna 3 is pulled out from the storage part first.

Conventionally, on-board antennas for this type of unmanned aerial vehicle have either been attached along the surface of the aircraft body, or mounted so as to protrude from the exterior of the aircraft body. In the former type of machine, the antenna is molded to match the shape of the aircraft and is glued or screwed to a part of the fuselage or wing.

In the latter mounting method, the antenna is held at a position slightly extended from the body using a stay or the like, or a mounting seat for the antenna is provided in a part of the body.

In the conventional antenna mounting method described above, when mounting on the surface of the aircraft, it is difficult to obtain the desired performance because the antenna must be designed to match the formation of the fuselage or wings. It has the disadvantage that it is difficult to manufacture because it requires processing.

Additionally, if the antenna is extended over a part of the aircraft, it needs to be strong enough to withstand the impact when the drone is launched or recovered, and it must also be made strong enough to withstand the impact when the drone is launched or recovered, and it also needs to be made strong so that it will not come into contact with the ground when it lands with a recovery net or parachute. It is necessary to attach a protective frame etc. to prevent damage. This increases power resistance and weight, making it difficult to mount a large antenna.

Furthermore, these antenna mounting systems have the disadvantage that when the unmanned aircraft is recovered at sea, the antenna itself must be constructed in a watertight manner, requiring a radome or the like.

Furthermore, when recovering an unmanned aircraft at sea, by making the door of the antenna storage section of the aircraft watertight, the antenna itself does not need to be watertight, and the weight can be reduced. Furthermore, since the large antenna can be held away from the aircraft body, it is possible to reduce radio wave interference with the aircraft body, and it also has the effect of minimizing turbulence in the airflow against the engine air intake or the wings.
