Book excerpt: Results from a wind tunnel. test of a delta wing UAV behind a KC-135R are presented and compared with predictions from a planar vortex lattice code. Both the predictions and data show wake interference effects on the UAV that vary significantly with relative lateral and vertical position, and weakly with relative longitudinal position. Predicted trends are excellent for all force and moments except for drag, and magnitudes are reasonably well predicted. The distribution of lift between the tanker wing and tail is shown to have a strong effect on the receiver aerodynamics.

Available in PDF, EPUB and Kindle. Book excerpt: Air-to-air refueling is important to the military for enabling aircraft to remain in the air for long periods of time, reducing the need for forward bases, and allowing aircraft to stay on mission for longer intervals. Although this has been available for traditional military aircraft for several decades, it has not been implemented for the use of Unmanned Aerial Vehicles (UAV). This thesis uses a panel method, VSAERO, to examine the effects that a large tanker aircraft will have on a small unmanned aerial vehicle during a refueling process. The primary cause of conditions behind the tanker aircraft is the wake generated by the wingtip vortices of the aircraft. The planes used for this analysis were an Airbus A320 as the tanker, and a General Atomic MQ-9 as the receiver. The techniques used were to examine literature on aerial refueling, and analyze the aerodynamic characteristics of the UAV. The most important properties that were examined were the rolling moment, pitching moment, and lift. These characteristics were used to determine the feasibility of the UAV being able to withstand the conditions behind the A320. Through the analysis of the MQ-9’s aerodynamic characteristics when in ideal conditions, along with its maximum rolling moment, and those same characteristics when flying behind the tanker, it was determined that the MQ-9 would be able to maintain position behind an A320 in order to complete the aerial refueling process.

This book was released on 2007 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Unmanned aircraft are rapidly becoming the platform of choice for military and governmental leaders. In recent years, the United States Government has expressed great interest in Unmanned Aircraft Systems (UAS) for military and other governmental agencies. With an almost insatiable appetite to gain information immediately, commanders want a persistent, responsive platform at their beck and call. However, the demand greatly outnumbers the availability of platforms, so leaders are looking at the possibility of air refueling unmanned platforms that will prolong their loiter time. Because of the senior leader pressure to get a persistent presence of unmanned aircraft through air refueling, they might have waived the "sanity check" for this, or overlooked a better way to achieve the goal. The future force of 2025 will undoubtedly include many unmanned aircraft and manned aircraft. This thesis investigates how aerial refueling and unmanned aircraft will interact in the future. The author concludes that tanker aircraft modified with multiple drogue refueling points, flying in an anchor orbit, or using track refueling would best augment future unmanned aircraft operations.

Available in PDF, EPUB and Kindle. Book excerpt: The Air Force has recognized a growing need for an air refueling capability on Unmanned Air Vehicles (UAVs) as these programs have developed. Such a capability will allow the UAVs to deploy into theater, extend their combat range and add to their persistence in the battle area. The Air Force Research Laboratory's (AFRL's) Human Effectiveness Directorate, Warfighter Interface Division, System Control Interface Branch's (AFRL/HECI) Unmanned Combat Air Vehicle - Operator/Vehicle Interface (UCAV-OVI) Laboratory has developed prototype control station interfaces for controlling multiple unmanned air vehicles during the air refueling phase of flight. A simulation evaluation was initiated to allow various subject matter experts (SMEs) the opportunity to review and comment upon the features and preliminary design concepts of these display interfaces. As a baseline evaluation, the intent was to collect subjective data and determine if there were any major flaws with the design. The SMEs provided excellent comments and suggestions and there were no major obstacles to completing the air refueling task.

Available in PDF, EPUB and Kindle. Book excerpt: Aerial refueling capabilities are an essential enabler of U.S. power projection and other critic at national missions. OPERATIONS ENDURING and IRAQI FREEDOM (OEF and OIF) could not have happened without these aerial refueling capabilities. Aerial refueling makes possible rapid deployment of forces to contingencies and the elective employment of those forces in the contingencies. In OIF there were over 8500 aerial refueling sorties flown and about 450 million pounds of fuel off loaded. In addition, aerial refueling remains a critical element in supporting the bomber leg of U.S. nuclear forces and other special national security missions. The task force was charged to evaluate current aerial refueling capability and to identify and evaluate alternative means of meeting future aerial refueling requirements.

This book was released on 2018-06-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The integration of uninhabited aerial vehicles (UAVs) into controlled airspace has generated a new era of autonomous technologies and challenges. Autonomous aerial refueling would enable UAVs to travel further distances and loiter for extended periods over time-critical targets. The NASA Dryden Flight Research Center recently has completed a flight research project directed at developing a dynamic hose and drogue system model to support the development of an automated aerial refueling system. A systematic dynamic model of the hose and drogue system would include the effects of various influences on the system, such as flight condition, hose and drogue type, tanker type and weight, receiver type, and tanker and receiver maneuvering. Using two NASA F/A-18 aircraft and a conventional hose and drogue aerial refueling store from the Navy, NASA has obtained flight research data that document the response of the hose and drogue system to these effects. Preliminary results, salient trends, and important lessons are presentedHansen, Jennifer L. and Murray, James E. and Campos, Norma V.Armstrong Flight Research CenterAIR TO AIR REFUELING; DYNAMIC MODELS; AUTONOMY; F-18 AIRCRAFT; TIME DEPENDENCE

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Autonomous Aerial Refueling of Unmanned Aerial Vehicles (UAV-AAR) has been determined to be possible through the development of an autonomous system with terminal guidance capabilities for a probe-and-drogue refueling configuration. An aircraft tanker and UAV were selected for analysis and determination of system constraints. The UAV's mechanics and performance characteristics were determined to understand the aircraft's stability and controllability characteristics. A hardware system necessary for autonomously docking the probe with the drogue was developed using colored light emitting diodes. The flow-field behind an aircraft tanker wing was analyzed to understand the effects of the wake acting on the aircraft to be refueled, and to determine where the pilot must initiate the terminal guidance system. From this analysis, it was determined that the UAV will enter the dangerous flow-field at about 175 feet behind the location of the drogue, approximately 250 feet from the tanker's wing. This area was named the terminal flight arena - the area in which the pilot can no longer control the UAV without a guidance system. Multiple fixed-flight paths for this flight arena were analyzed to determine changing forces acting on the UAV. Utilizing the determined performance characteristics, the control surface deflections necessary for steady flight through these fixed-flight paths were calculated. The best fixed-flight path for UAV-AAR was a path angled ten degrees below a horizontal path, which resulted in the most minimal change of control surface deflection throughout the terminal flight arena. The overall fixed-flight path control surface deflection analysis will be used to assist in developing a strategy for an autonomous system. The Dual-Optimal Path-Planning technique will be implemented for development of the autonomous system for terminal guidance. The technique will follow a given loop which will allow the UAV to fly within a predetermined window based on the UAV's maneuvering abilities, the locations of minimum induced force that will act on the UAV, the location and orientation of the drogue, and the quickest path for approach and a successful rendezvous.
