No part of this publication may be reproduced without the written permission of the copyright owner. ABSTRACT This report addresses the author’s Group Design Project (GDP) and Individual Research Project (IRP). The IRP is discussed primarily herein, presenting the actuation technology for the Flight Control System (FCS) on civil aircraft. Actuation technology is one of the key technologies for next generation More Electric Aircraft (MEA) and All Electric Aircraft (AEA); it is also an important input for the preliminary design of the Flying Crane, the aircraft designed in the author’s GDP. Information regarding actuation technologies is investigated firstly. After initial comparison and engineering consideration, Electrohydrostatic Actuation (EHA) and variable area actuation are selected for further research. The tail unit of the Flying Crane is selected as the case study flight control surfaces and is analysed for the requirements. Based on these requirements, an EHA system and a variable area actuation system powered by localised hydraulic systems are designed and sized in terms of power, mass and Thermal Management System (TMS), and thereafter the reliability of each system is estimated and the safety is analysed.

  • Lockheed Martin F-35 Lightning II Incorporates Many Significant Technological Enhancements Derived from Predecessor Development Programs
    AIAA AVIATION Forum 10.2514/6.2018-3368 June 25-29, 2018, Atlanta, Georgia 2018 Aviation Technology, Integration, and Operations Conference F-35 Air Vehicle Technology Overview Chris Wiegand,1 Bruce A. Bullick,2 Jeffrey A. Catt,3 Jeffrey W. Hamstra,4 Greg P. Walker,5 and Steve Wurth6 Lockheed Martin Aeronautics Company, Fort Worth, TX, 76109, United States of America The Lockheed Martin F-35 Lightning II incorporates many significant technological enhancements derived from predecessor development programs. The X-35 concept demonstrator program incorporated some that were deemed critical to establish the technical credibility and readiness to enter the System Development and Demonstration (SDD) program. Key among them were the elements of the F-35B short takeoff and vertical landing propulsion system using the revolutionary shaft-driven LiftFan® system. However, due to X- 35 schedule constraints and technical risks, the incorporation of some technologies was deferred to the SDD program. This paper provides insight into several of the key air vehicle and propulsion systems technologies selected for incorporation into the F-35. It describes the transition from several highly successful technology development projects to their incorporation into the production aircraft. I. Introduction HE F-35 Lightning II is a true 5th Generation trivariant, multiservice air system. It provides outstanding fighter T class aerodynamic performance, supersonic speed, all-aspect stealth with weapons, and highly integrated and networked avionics. The F-35 aircraft

    Advisory u.s. Department ofTransportation Federal Aviation Circular Ad.nnlstratlon Subject: CRITERIA FOR OPERATIONAL Date: 3/18/97 AC No: 120-67 APPROVAL OF AUTO FLIGHT Initiated By: AFS-400 Change: GUIDANCE SYSTEMS 1. PURPOSE. This advisory circular (AC) states an acceptable means, but not the only means, for obtaining operational approval of the initial engagement or use of an Auto Flight Guidance System (AFGS) under Title 14 of the Code of Federal Regulations (14 CFR) part 121, section 121.579(d); part 125, section 125.329(e); and part 135, section 135.93(e) for the takeoff and initial climb phase of flight. 2. APPLICABILITY. The criteria contained in this AC are applicable to operators using commercial turbojet and turboprop aircraft holding Federal Aviation Administration (FAA) operating authority issued under SPAR 38-2 and 14 CFR parts 119, 121, 125, and 135. The FAA may approve the AFGS operation for the operators under these parts, where necessary, by amending the applicant's operations specifications (OPSPECS). 3. BACKGROUND. The purpose of this AC is to take advantage of technological improvements in the operational capabilities of autopilot systems, particularly at lower altitudes. This AC complements a rule change that would allow the use of an autopilot, certificated and operationally approved by the FAA, at altitudes less than 500 feet above ground level in the vertical plane and in accordance with sections 121.189 and 135.367, in the lateral plane. 4. DEFINITIONS. a. Airplane Flight Manual (AFM). A document (under 14 CFR part 25, section 25.1581) which is used to obtain an FAA type certificate.

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.

  • Fly-By-Wire: Getting Started on the Right Foot and Staying There…
    Fly-by-Wire: Getting started on the right foot and staying there… Imagine yourself getting into the cockpit of an aircraft, finishing your preflight checks, and taxiing out to the runway ready for takeoff. You begin the takeoff roll and start to rotate. As you lift off, you discover your side stick controller is not responding correctly to your commands. Panic sets in, and you feel that you’ve lost total control of the aircraft. Thanks to quick action from your second in command, he takes over and stabilizes the aircraft so that you both can plan to return to the airport under reversionary mode. This situation could have been a catastrophe. This happened in August of 2001. A Lufthansa Airbus A320 came within less than two feet and a few seconds of crashing during takeoff on a planned flight from Frankfurt to Paris. Preliminary reports indicated that maintenance was performed on the captain’s sidestick controller immediately before the incident. This had inadvertently created a situation in which control inputs were reversed. The case reveals that at least two "filters," or safety defenses, were breached, leading to a near-crash shortly after rotation at Frankfurt’s Runway 18. Quick action by the first officer prevented a catastrophe. Lufthansa Technik personnel found a damaged pin on one segment of the four connector segments (with 140 pins on each) at the "rack side," as it were, of the avionics mount. This incident prompted an article to be published in the 2003 November-December issue of the Flight Safety Mechanics Bulletin. The report detailed all that transpired during the maintenance and subsequent release of the aircraft.

The risks inherent in digital flight control systems, like the Space Shuttle, are identified. The results of a literature survey examining risk management methods in use throughout the aerospace industry are presented. The applicability of these methods to the Space Shuttle program is discussed. Introduction Since the development of the Space Shuttle, many other aerospace vehicles have incorporated fly-by-wire technologies in their flight control systems in an effort to improve performance, efficiency, and reliability. Because the flight control system is a critical component of any aerospace vehicle, it is especially important that the risks inherent in using fly-by-wire technologies are thoroughly understood and carefully managed.
