A system performs a control method to launch an unmanned aerial vehicle, UAV. The control method includes calculating a selected altitude, relative to a reference level, for launching the UAV, operating a lifting arrangement to vertically elevate the UAV to the selected altitude, and causing the UAV to be launched from the selected altitude. Elevating the UAV may improve the performance of the UAV in terms of range, power consumption, ability to carry payload, transit time to destination, etc. The selected altitude may be calculated as a function of parameter data representing any of the UAV, the lifting arrangement, or surrounding conditions. An apparatus is further provided to determine an optimal location of the system in relation to a plurality of destinations of UAVs to be elevated by the system.

An aircraft assist system described herein includes an aircraft coupling counterpart attached to a strut of a landing gear of an aircraft, and an assist vehicle. The assist vehicle includes a frame, ground-engaging wheels mounted to the frame, a power source for driving one or more of the ground-engaging wheels, and a vehicle coupling counterpart for engagement with the aircraft coupling counterpart. The aircraft coupling counterpart and the vehicle coupling counterpart define a swivel connection for transferring a propulsive force from the takeoff assist vehicle to the aircraft. The aircraft coupling counterpart is disengageable from the vehicle coupling counterpart by upward movement of the aircraft coupling counterpart relative to the vehicle coupling counterpart.

One variation of a tram system includes: a chassis; a latch configured to selectively engage a latch receiver mounted to an aircraft; an alignment feature adjacent the latch and configured to engage an alignment receiver mounted to the aircraft and to communicate acceleration and braking forces from the chassis into the aircraft; an optical sensor facing upwardly from the chassis; a drivetrain configured to accelerate and decelerate the chassis along a runway; and a controller configured to detect an optical fiducial arranged on the aircraft in optical images recorded by the optical sensor adjust a speed of the drivetrain to longitudinally align the alignment feature with the alignment receiver based on positions of the optical fiducial detected in the optical images, trigger the latch to engage the latch receiver once the aircraft has descended onto the chassis, and trigger the drivetrain to actively decelerate the chassis during a landing routine.

A system comprises a drone having autonomous drive capability and an assist vehicle (AV) for transporting the drone in an assisted drive mode in which the drone is held at, and transported by, the assist vehicle. Control hardware and software are programmed to determine drone travel over a route having a first route section in which the drone travels autonomously and a second route section in which the drone travels in the assisted drive mode.

A launchpad is sized and shaped to accommodate an autonomous vehicle (AV) that includes at least one vehicle sensor. The launchpad includes one or more launchpad sensors located on or around the launchpad. A control subsystem receives launchpad sensor data from the launchpad sensor(s) and AV sensor data from the vehicle sensor(s). In response to the request for departure of the AV, the control subsystem determines, based at least in part upon the launchpad sensor data, whether the launchpad is free of obstructions that would prevent departure from the launchpad and determines, based at least in part upon the AV sensor data, whether the region in front of the AV is clear of obstructions that would prevent movement away from the launchpad. If both the launchpad and the region in front of the AV are free of obstructions, the AV is permitted to begin driving autonomously.
