The canard had an exposed area of 16.0 percent of the wing reference area and was located in the plane of the wing or in a position 18.5 percent of the wing mean geometric chord above the wing plane. In addition, the canard could be located at two longitudinal stations. -
Air Force Next-Generation Bomber: Background and Issues for Congress
Air Force Next-Generation Bomber: Background and Issues for Congress Jeremiah Gertler Specialist in Military Aviation December 22, 2009 Congressional Research Service 7-5700 www.crs.gov RL34406 CRS Report for Congress Prepared for Members and Committees of Congress Air Force Next-Generation Bomber: Background and Issues for Congress Summary As part of its proposed FY2010 defense budget, the Administration proposed deferring the start of a program to develop a next-generation bomber (NGB) for the Air Force, pending the completion of the 2010 Quadrennial Defense Review (QDR) and associated Nuclear Posture Review (NPR), and in light of strategic arms control negotiations with Russia. The Administration’s proposed FY2010 budget requested no funding specifically identified in public budget documents as being for an NGB program. Prior to the submission of the FY2010 budget, the Air Force was conducting research and development work aimed at fielding a next-generation bomber by 2018. Although the proposed FY2010 defense budget proposed deferring the start of an NGB program, the Secretary of Defense and Air Force officials in 2009 have expressed support for the need to eventually start such a program. The Air Force’s FY2010 unfunded requirements list (URL)—a list of programs desired by the Air Force but not funded in the Air Force’s proposed FY2010 budget—includes a classified $140-million item that some press accounts have identified as being for continued work on a next-generation bomber.

Fly-by-wire - Wikipedia, the free encyclopedia 11-8-20 下午5:33 Fly-by-wire From Wikipedia, the free encyclopedia Fly-by-wire (FBW) is a system that replaces the Fly-by-wire conventional manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals transmitted by wires (hence the fly-by-wire term), and flight control computers determine how to move the actuators at each control surface to provide the ordered response. The fly-by-wire system also allows automatic signals sent by the aircraft's computers to perform functions without the pilot's input, as in systems that automatically help stabilize the aircraft.[1] Contents Green colored flight control wiring of a test aircraft 1 Development 1.1 Basic operation 1.1.1 Command 1.1.2 Automatic Stability Systems 1.2 Safety and redundancy 1.3 Weight saving 1.4 History 2 Analog systems 3 Digital systems 3.1 Applications 3.2 Legislation 3.3 Redundancy 3.4 Airbus/Boeing 4 Engine digital control 5 Further developments 5.1 Fly-by-optics 5.2 Power-by-wire 5.3 Fly-by-wireless 5.4 Intelligent Flight Control System 6 See also 7 References 8 External links Development http://en.wikipedia.org/wiki/Fly-by-wire Page 1 of 9 Fly-by-wire - Wikipedia, the free encyclopedia 11-8-20 下午5:33 Mechanical and hydro-mechanical flight control systems are relatively heavy and require careful routing of flight control cables through the aircraft by systems of pulleys, cranks, tension cables and hydraulic pipes. -

Also, read the aircraft classification handout provided in class. Examine the FAA Advisory Circular 150/5300-13 (Airport Design). Specifically examine Appendix 13 of the FAA Advisory Circular which contains information about various aircraft. a) For the aircraft shown in Table 2.1, state the Airplane Design Group (ADG) class, the Terminal Areas Procedures Aircraft Speed Category, and the wake vortex class for each vehicle. b) For each aircraft, calculate the stalling speed (minimum speed for flight) from the known aircraft approach speeds published in the FAA AC. Stalling speed is just 30% below the approach speed. Table 2.1 Aircraft to be Studied.

2021-03 Pearcey Newby and the Vulcan V2.Pdf
Journal of Aeronautical History Paper 2021/03 Pearcey, Newby, and the Vulcan S C Liddle Vulcan to the Sky Trust ABSTRACT In 1955 flight testing of the prototype Avro Vulcan showed that the aircraft’s buffet boundary was unacceptably close to the design cruise condition. The Vulcan’s status as one of the two definitive carrier aircraft for Britain’s independent nuclear deterrent meant that a strong connection existed between the manufacturer and appropriate governmental research institutions, in this case the Royal Aircraft Establishment (RAE) and the National Physical Laboratory (NPL). A solution was rapidly implemented using an extended and drooped wing leading edge, designed and high-speed wind-tunnel tested by K W Newby of RAE, subsequently being fitted to the scaled test version of the Vulcan, the Avro 707A. Newby’s aerodynamic solution exploited a leading edge supersonic-expansion, isentropic compression* effect that was being investigated at the time by researchers at NPL, including H H Pearcey. The latter would come to be associated with this ‘peaky’ pressure distribution and would later credit the Vulcan implementation as a key validation of the concept, which would soon after be used to improve the cruise efficiency of early British jet transports such as the Trident, VC10, and BAC 1-11. In turn, these concepts were exploited further in the Hawker-Siddeley design for the A300B, ultimately the basis of Britain’s status as the centre of excellence for wing design in Airbus.

Photo: Liam Marshall TABLE OF CONTENTS Bombers / Attack Fighters Multirole Helicopters Reconnaissance / Surveillance Trainers OV-101 Enterprise Concorde Aircraft Restoration Hangar Photo: Liam Marshall BOMBERS/ATTACK The basic mission of the aircraft carrier is to project the U.S. Navy’s military strength far beyond our shores. These warships are primarily deployed to deter aggression and protect American strategic interests. Should deterrence fail, the carrier’s bombers and attack aircraft engage in vital operations to support other forces. The collection includes the 1940-designed Grumman TBM Avenger of World War II. Also on display is the Douglas A-1 Skyraider, a true workhorse of the 1950s and ‘60s, as well as the Douglas A-4 Skyhawk and Grumman A-6 Intruder, stalwarts of the Vietnam War.

Originally built as the TBF by Grumman Aircraft Engineering Corporation, they were affectionately nicknamed “Turkeys” for their somewhat ungainly appearance.
