    Abstract: Disclosed is a technique for landing a drone using a parachute. The technique includes a parachute deployment system (PDS) that can deploy a parachute installed in a drone and land the drone safely. The parachute may be deployed automatically, e.g., in response to a variety of failures such as a free fall, or manually from a base unit operated by a remote user. For example, the PDS can determine the failure of the drone based on data obtained from an accelerometer, a gyroscope, a magnetometer and a barometer of the drone and automatically deploy the parachute if any failure is determined. In another example, the remote user can "kill" the drone, that is, cut off the power supply to the drone and deploy the parachute by activating an onboard "kill" switch from the base unit.

    Abstract: A semi-levered landing gear for an aircraft comprises a main shock absorber strut (1) connected to the airframe; a bogie beam (4) extending fore and aft of the airframe with forward and aft wheels (J, T) and a main pivot connection (5) to the strut (1) between the forward and aft wheels (7, T) and an auxiliary actuator (49) connected between the strut (1) and the front of the bogie beam (4) at an auxiliary pivot (14). The auxiliary actuator (49) comprises a two stage telescopic hydraulic unit comprising a first stage piston and cylinder actuator (59, 63) and a second stage piston and cylinder actuator (56, 50) operating coaxially within an outer casing (50). A respective piston rod (65, 60) each extends from each end of the casing (50) and is connected to a respective one of said (strut 1) and bogie beam (4). The first stage actuator (59, 63) is operable to an extended position, and the second stage actuator (56, 60) is operable between a retracted position (Fig. 11) and an extended position (Fig. 12) defined by respective end stops (75, 77) within the outer casing (50) and serves to control the tilt position of the bogie beam (4) relative to the strut (1). The second stage actuator (56, 60), when in the retracted position with the first stage actuator (59, 63) in the extended position, limits the length of the auxiliary actuator (9) between its connections (62, 67) to the strut (1) and bogie beam (4), so as to assume a predetermined intermediate length in which the bogie beam (4) is restrained to tilt about the auxiliary pivot (14) and thereby lengthens the landing gear during take-off. The second stage actuator (56, 60), when in the extended position with the first stage actuator (59, 63) in the extended position, allows the length of the auxiliary actuator (49) to assume a predetermined maximum length in which the bogie beam (4) is tilted about the main pivot (5) to a stowing position for stowing the landing gear in the aircraft.

    Abstract: An electronic device checks the pressure of an aircraft landing gear oleo by means of a camera capturing and processing an image of the oleo. An image recognition module processes the oleo image to extract a measure of the amount of extension of the oleo. This measure is then processed together with a measure of oleo temperature to calculate a pressure value representative of the expected pressure of the gas within the oleo, which can then be compared with another measurement of oleo pressure to determine whether the two are consistent or whether the oleo might be under- or over-filled with gas. The electronic device may be in the form of a hand-held smart phone or tablet device appropriately programmed with software.

    Abstract: An electric tail-sitter aircraft configured to transport passengers and/or cargo between locations. The aircraft includes a flight module, a ground module and a payload module. The flight module is a wing that can rotate with respect to the rest of the aircraft, from vertical to horizontal and vice versa. A plurality of electrically driven propellers are attached to the wing, providing vector thrusting (through the rotation of the wing) and differential thrusting to control the different phases of the flight (vertical take-off and landing, horizontal, transition between the previous two). The payload module is an interchangeable component that can be a cabin for passenger transportation or a cargo container. It can actively shift its position in the aircraft in order to control the center of gravity position. The ground module may include wheels, a transmission, suspension, and carry the payload module. It is connected to the flight module through an L-shaped hinge, where the wing rotates to a plane behind the hinging point, in order to have the center of gravity adjusted as to be located on the hinging axis.
