Preliminary Project of the Autonomous Landing System for Unmanned Aircraft

1999-10-19
1999-01-5524
The autonomous control of an aircraft under the flare and touch-down maneuvers is an interesting problem of both theoretical and practical nature. ...In this paper, a concept of the autonomous landing system (ALS) for unmanned air vehicles (UAV) is presented. The flight control system is addressed to the low-cost, civilian, medium-size UAV with relatively low approach speed and typical nose-wheel landing gear. ...When the flight control system selects the LANDING option at chosen altitude (based on GPS and pressure altitude), a change in aircraft’s attitude is executed. New attitude ensures safe flare and touchdown of the unmanned aircraft.

Guidance Concept for a Receiver Aircraft to Perform Autonomous Aerial Refueling

2007-09-17
2007-01-3816
An adaptive trajectory concept that exploits the capabilities of a fixed-gain set 6-DOF autopilot was developed for autonomous aerial refueling. The concept was based on differential position error feedback that was used to control overshoot and tracking speed about the tanker refueling point. ...To demonstrate this concept, an automatic aerial refueling flight system simulation for a conventional receiving aircraft was developed. The performance of the system was then evaluated for a selected differential position, flight condition, and atmospheric disturbance.

Autonomous Flight Control Development on the Active Aeroelastic Wing Aircraft

A highly modified F/A-18 aircraft is being used to demonstrate that aeroelastic wing twist can be used to roll a high performance aircraft. A production F/A-18A/B/C/D aircraft uses a combination of aileron deflection, differential horizontal tail deflection and differential leading edge flap deflection to roll the aircraft at various Mach numbers and altitudes. ...Now control laws have been developed to exploit aeroelastic wing twist and provide autonomous flight control of the AAW aircraft during Phase II. Wing control surfaces are being deflected in non-standard ways to create aeroelastic wing twist and develop the required rolling moments without use of the horizontal tail. ...Control inputs would be the same as for conventional aircraft, but rolling and pitching moment can be achieved through a variety of autonomous control surface inputs, including the wing as a control surface in and of itself.

Autonomous Technologies: Applications That Matter

2014-09-03
Over the years, the DARPA Challenges in the United States have galvanized interest in autonomous cars, making them a real possibility in the mind of the public, but autonomous and unmanned vehicles have been increasingly employed in many roles on land, in the water, and in the air. ...This book examines a number of economically important areas in which unmanned and autonomous vehicles, also understood here as autonomous technologies, are already used or soon will be. ...Military applications have received a great deal of attention, with weaponized unmanned aircraft (drones) being the most prominent. However, unmanned vehicles with varying degrees of autonomy already have many civilian applications.

Today's civil airliners integrate electrical power capability properly sized to supply the growing demands of modern aircraft systems, that are more electrical than ever. The conversion of civil aircraft into a military derivative aircraft faces the challenge of rearranging the available generation capability to feed the new power-hungry military systems while at the same time minimizing the impact on certification of the base aircraft for use on civil operations. ...The conversion of civil aircraft into a military derivative aircraft faces the challenge of rearranging the available generation capability to feed the new power-hungry military systems while at the same time minimizing the impact on certification of the base aircraft for use on civil operations. ...The conversion of civil aircraft into a military derivative aircraft faces the challenge of rearranging the available generation capability to feed the new power-hungry military systems while at the same time minimizing the impact on certification of the base aircraft for use on civil operations. This challenge is particularly difficult when the new military systems demand high peak power consumption, as in the case of the conversion of a civil airliner into a military Multi-Role Transport Tanker aircraft with high performance multipoint refueling capabilities.

An outer loop guidance architecture was designed to control autonomous aerial refueling mission from the trail aircraft side. The design utilized bank, yaw rate, velocity and climb rate commands implemented using a previously developed adaptive trajectory concept. ...The concept was based on position error feedback that was used to control trail aircraft overshoot and tracking about the lead aircraft refueling point. To demonstrate this application, an open loop linear trail aircraft model at a given flight condition was selected. ...To demonstrate this application, an open loop linear trail aircraft model at a given flight condition was selected. Inner loop control laws were designed using Linear Quadratic Regulator feedback controller and Balanced Deviation theory.

In this paper, an intelligent autonomous deck landing system is designed for an Unmanned Air Vehicle (UAV). First, the design specifications and requirements are identified for the design of UAV flight control and landing systems. ...Then the longitudinal models of the UAV are established for the design of an autonomous UAV landing system. The system is designed using fuzzy logic, which is able to provide longitudinal stability and to improve the tracking performance. ...This indicates that the intelligent landing system has the ability to stabilize a damaged aircraft without knowledge of the types of fault or system parameters. Wind disturbances are also investigated by using the turbulence model for the ship-landing environment.
