They b oth served with the 380th Bomb Wing SAC Plattsburg AFB before being sent to an Arizona boneyard. In 1994 they were rescued by the RAAF and soldiered on until 2010 mostly out of Amberely in Queensland. Once again they were retired and supposedly cut up for scrap or [put on static display (So everyone thought). What actually happened is a different story. Several airfra mes did become gate post decorations and many were scrapped, but not all of them. Wrangler, Double Trouble and a handful of other airframes went somewhere else – along with a bunch of others fr om the Arizonas desert. F‐111G, A8‐272 the ‘Boneyard Wrangler’, as far the public are aware, is on display at the RAAF Museum at Point Cook near Melbourne. -

Fantasy Topgun Adven
Fantasy TopGun Adventure Emile Niu Jan. 2002 As a boy, I first read about the F-14 Tomcat fighters from Reader's Digest. At times it seem so remote, I could only dream of being a fighter pilot. During mid-1990s, I participated in certain California flying clubs and learned about the news of civilian flying military jets. The news described a program organized by a company MiG, Etc., which put civilian in training and behind the stick of active Migs and Sukhoi fighters. The venture started in 1992 when an investment banker was striking a deal in Moscow found his way to the cockpit of a MiG fighter as a courtesy ride offered by local authority. He then commercialized the activity and marketed the program in the States. I found the fax number of this Florida Company from a Smithsonian magazine and decided to send inquiry to check out the details. It turned out the company was acquired by another party and was renamed "Incredible Adventures". I received fax leaflets on the details of the flights and six months later; I signed up for the program. It was October 1996, the afternoon weather a bit chili when I finally arrived in Sheremetyero, Moscow. It was a long flight from Hong Kong through transit in London. From the airport, the agent transferred me to Hotel Metropol (same hotel as the movie Dr. Zhivago) where I met James Weber, another TopGun wannabes. The next morning, James and I were transported to Zhukovsky Air Base, the formerly classified military area established during the Soviet era on the outskirts of Moscow as the research and development center of the aviation industry. -

Computational Challenges in High Angle of Attack Flow Prediction
Computational challenges in high angle of attack flow prediction a b b C Russell M. Cummings , James R. Forsythe , Scott A. Morton , Kyle D. Squires a Aerospace Engineering Department, California Polytechnic State University, San Luis Obispo, CA 93407, USA b Department of Aeronautics, United States Air Force Academy, USAF Academy, CO 80840, USA C Department of Mechanical and Aerospace Engineering, Arizona State University, Tempe, AZ 85287, USA Abstract Aircraft aerodynamics have been predicted using computational fluid dynamics for a number of years. While viscous flow computations for cruise conditions have become commonplace, the non-linear effects that take place at high angles of attack are much more difficult to predict. A variety of difficulties arise when performing these computations, including challenges in properly modeling turbulence and transition for vortical and massively separated flows, the need to use appropriate numerical algorithms if flow asymmetry is possible, and the difficulties in creating grids that allow for accurate simulation of the flowfield. These issues are addressed and recommendations are made for further improvements in high angle of attack flow prediction. Current predictive capabilities for high angle of attack flows are reviewed, and solutions based on hybrid turbulence models are presented. Contents I. Introduction 370 2.

Learning Pugachev's Cobra Maneuver for Tail-Sitter Uavs Using
IEEE ROBOTICS AND AUTOMATION LETTERS. PREPRINT VERSION. ACCEPTED FEBRUARY, 2020 1 Learning Pugachev’s Cobra Maneuver for Tail-sitter UAVs Using Acceleration Model Wei Xu1, Fu Zhang1 Abstract—The Pugachev’s cobra maneuver is a dramatic and demanding maneuver requiring the aircraft to fly at extremely high Angle of Attacks (AOA) where stalling occurs. This paper considers this maneuver on tail-sitter UAVs. We present a simple yet very effective feedback-iterative learning position control structure to regulate the altitude error and lateral displacement during the maneuver. Both the feedback controller and the Fig. 1. The Pugachev’s Cobra Maneuver 2. iterative learning controller are based on the aircraft accel- eration model, which is directly measurable by the onboard Although there are a few prior work on the control of fixed- accelerometer. Moreover, the acceleration model leads to an wing UAVs in post-stall maneuvers, such as [7]–[9], none of extremely simple dynamic model that does not require any model identification in designing the position controller, greatly them directly cope with the Pugachev manuever. Another way simplifying the implementation of the iterative learning control. is to view this maneuver as a backward transition (from level Real-world outdoor flight experiments on the “Hong Hu” UAV, flight to vertical flight) immediately followed by a forward an aerobatic yet efficient quadrotor tail-sitter UAV of small-size, transition (from vertical flight to level flight). For the control are provided to show the effectiveness of the proposed controller. of the transition flight, a large number of researches could be found. In [10], three transition controllers were investigated I.
