Air Force OA-X Light Attack Aircraft/SOCOM Armed Overwatch Program
Updated March 30, 2021 Air Force OA-X Light Attack Aircraft/SOCOM Armed Overwatch Program On October 24, 2019, the U.S. Air Force issued a final OA-X, its ability to operate with coalition partners, and to request for proposals declaring its intent to acquire a new initially evaluate candidate aircraft. The first phase included type of aircraft. The OA-X light attack aircraft is a small, four aircraft: the Sierra Nevada/Embraer A-29; two-seat turboprop airplane designed for operation in Textron/Beechcraft AT-6B; Air Tractor/L3 OA-802 relatively permissive environments. The announcement of a turboprops, variants of which are in service with other formal program followed a series of Air Force countries; and the developmental Textron Scorpion jet. “experiments” to determine the utility of such an aircraft. First-phase operations continued through August 2017. Following conclusion of the Air Force experiments, the program passed to U.S. Special Operations Command as Figure 1. Sierra Nevada/Embraer A-29 the “Armed Overwatch” program, with a goal of acquiring 75 aircraft. Why Light Attack? During 2018, then-Air Force Secretary Heather Wilson often expressed the purpose of a new light attack aircraft as giving the Air Force an ability to free up more sophisticated and expensive assets for other tasks, citing the example of using high-end F-22 jets to destroy a drug laboratory in Afghanistan as an inefficient use of resources. Per-hour operating costs for light attack aircraft are typically about 2%-4% those of advanced fighters. She and other officials have also noted that the 2018 Source: U.S. -
THE ROADMAP to Scalable Urban Air Mobility
THE ROADMAP to scalable urban air mobility White paper 2.0 We bring urban air mobility to life. FOREWORD BY THE CEO MAKING HISTORY When I joined Volocopter in 2015, an amazing team of innovators had already made aviation history. With a dream, a yoga ball,1 and a new configuration of distributed electric vertical takeoff and landing (eVTOL) technology, Volocopter pioneered the way for electric passenger flights as early as 2011. Since then, Volocopter has relentlessly pursued its dream and continued to make great strides. I have witnessed the idea of electric flight grow into a fully-fledged initiative to bring seamless urban air mobility to cities. It’s true, we developed a revolutionary aircraft. But in fact, we launched the creation of an entire industry. The yoga ball evolved into the first certified multicopter, and Volocopter evolved to become the world’s first and only electric multicopter company with Design Organisation Approval (DOA) from the European Union Aviation Safety Agency (EASA). Five years, six very public flights, and two city commitments later, Volocopter continues to lead the pack as the “Pioneer of Urban Air Mobility” both in certification and in robust partnerships. We have set the stage for the next transformative industry. BRINGING URBAN AIR MOBILITY TO LIFE As the category-defining company, we are investing in multidimensional mobility. And as a team, we are engineering it. Volocopter has combined cutting-edge eVTOL technology with a holistic partnership approach as we build the world’s first fully electric, scalable UAM business for affordable air taxi services in cities. -

PRESIDENT's MUSINGS OCTOBER 2015 Many of Us Attended The
PRESIDENT'S MUSINGS OCTOBER 2015 Many of us attended the Navy Ball at the Atrium Flemington Racecourse on October 17th, and the consensus is that it was a splendid occasion. Our congratulations go to the organising committee for a job well done. Personally I had a great time! Traditionally we have 'Show and Tell' as part of our AGM and we urge you to check out that trunk in the attic and share your treasures with your friends, who are sure to believe everything you tell them about it! Show and tell is a lot of fun and we are sure to share a few laughs together, as always! Rex's Odyssey – Part 1: My son, David, is working in Manila and so my trip, over two months, really started and ended in the Philippines. It was really great to catch up with the Williams family and be with them for a couple of weeks sharing their new environment. I'd like to also share with you my time at the American Cemetery in Manila and my day trip to Corregidor Island. The American Cemetery and Memorial is set on 152 acres, and burials number 17,201 most of who lost their lives in operations in the New Guinea and Philippines area. The headstones are aligned in 11 plots forming a generally circular pattern, set amongst lush lawns and beautiful trees white and shrubs. It is indeed a beautiful resting place which is maintained to perfection. The chapel building is situated near the centre of the complex and in front of it on a wide terrace are two large hemicycles containing 25 mosaic maps recalling the achievements of America and her allies in the Pacific, Chinese Indian and Burmese theatres during WWII. -
AMA FPG-9 Glider OBJECTIVES – Students Will Learn About the Basics of How Flight Works by Creating a Simple Foam Glider
AEX MARC_Layout 1 1/10/13 3:03 PM Page 18 activity two AMA FPG-9 Glider OBJECTIVES – Students will learn about the basics of how flight works by creating a simple foam glider. – Students will be introduced to concepts about air pressure, drag and how aircraft use control surfaces to climb, turn, and maintain stable flight. Activity Credit: Credit and permission to reprint – The Academy of Model Aeronautics (AMA) and Mr. Jack Reynolds, a volunteer at the National Model Aviation Museum, has graciously given the Civil Air Patrol permission to reprint the FPG-9 model plan and instructions here. More activities and suggestions for classroom use of model aircraft can be found by contacting the Academy of Model Aeronautics Education Committee at their website, buildandfly.com. MATERIALS • FPG-9 pattern • 9” foam plate • Scissors • Clear tape • Ink pen • Penny 18 AEX MARC_Layout 1 1/10/13 3:03 PM Page 19 BACKGROUND Control surfaces on an airplane help determine the movement of the airplane. The FPG-9 glider demonstrates how the elevons and the rudder work. Elevons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control). Thus, elevons at the wing trailing edge are used for pitch and roll control. They are frequently used on tailless aircraft such as flying wings. The rudder is the small moving section at the rear of the vertical stabilizer that is attached to the fixed sections by hinges. Because the rudder moves, it varies the amount of force generated by the tail surface and is used to generate and control the yawing (left and right) motion of the aircraft. -

McLaughlin Professor of Aerospace Engineering Thesis Advisor Joseph F. Horn Associate Professor of Aerospace Engineering Michael Krane Research Associate PSU Applied Research Laboratory George A. Lesieutre Professor of Aerospace Engineering Head of the Department of Aerospace Engineering *Signatures are on file in the Graduate School ii ABSTRACT Ducted fans and ducted rotors have been integrated into a wide range of aerospace vehicles, including manned and unmanned systems. Ducted fans offer many potential advantages, the most important of which is an ability to operate safely in confined spaces. There is also the potential for lower environmental noise and increased safety in shipboard operations (due to the shrouded blades). However, ducted lift fans in edgewise forward flight are extremely complicated devices and are not well understood. Future development of air vehicles that use ducted fans for lift (and some portion of forward propulsion) is currently handicapped by some fundamental aerodynamic issues. These issues influence the thrust performance, the unsteadiness leading to vehicle instabilities and control, and aerodynamically generated noise. Less than optimum performance in any of these areas can result in the vehicle using the ducted fan remaining a research idea instead of one in active service. -
