An unmanned aircraft traction control system without a traction rod and an intelligent tractor relate to the technical fields of aircraft ground motion and man-machine coordination. The traction control system includes an aircraft light identification and induction module, a main sensing system module, an aircraft sound identification and induction module and a control module which are arranged on the tractor. When the tractor and an aircraft carry out a wheel holding operation, the aircraft light identification and induction module, the main sensing system module and the aircraft sound identification and induction module acquire a brightness signal of an aircraft nose landing gear taxi light, an aircraft turning signal, an aircraft resistance signal and an aircraft horn signal autonomously transmitted by a pilot. The purpose that a pilot autonomously controls the tractor to pull an aircraft to an aircraft parking position or a designated taxiway position is realized through the above signals.

An aircraft tow vehicle comprises a turntable lifting unit configured to automatically rotate and lift for attachment to a nose landing gear of an aircraft. A gate coupled to the turntable lifting unit automatically unlocks, opens to receive the nose landing gear, closes to secure the nose landing gear, and locks. A sensor system detects the nose landing gear. A controller receives data from the sensor system, processes the data to determine a position of the nose landing gear, and controls the turntable lifting unit while automatically adjusting a position of the tow vehicle relative to the nose landing gear. A moving floor adjusts to accommodate different nose wheel sizes. A nose wheel adapter automatically positions itself to hold down the nose landing gear when weight is detected on the moving floor.

An airport collision avoidance system may include a tow vehicle configured to move an aircraft, the tow vehicle having a first beacon. The airport collision avoidance system may include at least one second beacon associated with at least one object. The airport collision avoidance system may include one or more processing circuits including one or more processors and one or more memories having instructions stored thereon that, when executed by the one or more processors, cause the one or more processors to: form a mesh network connection between the first beacon and the at least one second beacon; identify relative positionings between the tow vehicle, the aircraft, and the at least one object based on the mesh network connection; and at least partially control the tow vehicle based on the relative positionings between the tow vehicle, the aircraft, and the at least one object.

A towbarless tractor for towing an airplane having a nose landing gear includes a chassis, a body supported on the chassis, a tractive assembly, a driveline configured to drive and steer the tractive assembly, a braking system configured to apply a brake force to the tractive assembly, a capture system including an actuator configured to facilitate capturing the nose landing gear within the capture system, and a controller. The controller is acquire data regarding the airplane, and generate or modify, based on the data, at least one of (a) a steering command provided to the driveline as the capture system approaches the nose landing gear or (b) a side-shift command provided to the actuator as the capture system approaches the nose landing gear.

A towbarless tractor includes a chassis, a body supported on the chassis, a tractive assembly, a driveline configured to drive and steer the tractive assembly, a braking system configured to apply a brake force to the tractive assembly, and a controller. The controller is configured to command the driveline to autonomously follow a travel path taken from a home location to a pushback location in a reverse order to return from the pushback location to the home location, and determine, when navigating from the pushback location to the home location, if an object is in a return path from the pushback location to the home location.

A vehicle for towing an airplane includes a chassis, a body coupled to the chassis, the body and the chassis having a first side and a second side opposite the first side, a tractive assembly, a tow mechanism configured to engage with a nose landing gear of the airplane, a light system including a first lighting element positioned along the first side and a second lighting element positioned along the second side, and a control system configured to monitor a direction of travel of the vehicle and control operation of the light system to selectively illuminate the first lighting element and the second lighting element to provide an indication of the direction of travel of the vehicle, thereby making the direction of travel of the vehicle perceivable to an operator positioned outside of the vehicle.
