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.

  • PROPULSION SYSTEM/FLIGHT CONTROL INTEGRATION for SUPERSONIC AIRCRAFT Paul J
    PROPULSION SYSTEM/FLIGHT CONTROL INTEGRATION FOR SUPERSONIC AIRCRAFT Paul J. Reukauf and Frank W. Burcham , Jr. NASA Dryden Flight Research Center SUMMARY The NASA Dryden Flight Research Center is engaged in several programs to study digital integrated control systems. Such systems allow minimization of undesirable interactions while maximizing performance at all flight conditions. One such program is the YF-12 cooperative control program. In this program, the existing analog air-data computer, autothrottle, autopilot, and inlet control systems are to be converted to digital systems by using a general purpose airborne computer and interface unit. First, the existing control laws are to be programed and tested in flight. Then, integrated control laws, derived using accurate mathematical models of the airplane and propulsion system in conjunction with modern control techniques, are to be tested in flight. Analysis indicates that an integrated autothrottle-autopilot gives good flight path control and that observers can be used to replace failed sensors. INTRODUCTION Supersonic airplanes, such as the XB-70, YF-12, F-111, and F-15 airplanes, exhibit strong interactions between the engine and the inlet or between the propul- sion system and the airframe (refs. 1 and 2) . Taking advantage of possible favor- able interactions and eliminating or minimizing unfavorable interactions is a chal- lenging control problem with the potential for significant improvements in fuel consumption, range, and performance. In the past, engine, inlet, and flight control systems were usually developed separately, with a minimum of integration. It has often been possible to optimize the controls for a single design point, but off-design control performance usually suffered.

  • GENERAL ENGINE BLEED Fokker 50
    Fokker 50 - Bleed Air System GENERAL Bleed-air is used for airconditioning, pressurization, airframe and engine air intake de-icing, and for pressurizing the hydraulic tank. Bleed-air is supplied by the engines. For aircraft equipped with APU On the ground bleed-air can be supplied by the APU for air conditioning. ENGINE BLEED Tappings Bleed-air is obtained via tappings on each engine, referred to as Low-Pressure (LP) bleed and High-Pressure (HP) bleed. LP-bleed is normally in use during flight. HP-bleed will be used at idling and low engine speeds, when LP-bleed is insufficient. The HP-bleed valve will open automatically provided the BLEED push button, located at the AIR CONDITIONING panel, is blank. Bleed-air from the HP-Bleed is prevented from flowing into the LP-bleed by a check valve. Duct leak detection A duct leak between the engine tappings and the firewall, resulting in a significant leakage of bleed-air, is monitored by the engine fire detection and warning system. Distribution Bleed-air from both engines is used to supply the following services: • Airframe, and engine air intake de-icing, see ICE AND RAIN PROTECTION • Hydraulic tank pressurization, see HYDRAULIC SYSTEM. • Airconditioning and pressurization, see below. • If mentioned in aircraft system deviation table: Watertank pressurization, see AIRCRAFT GENERAL. Page 1 Fokker 50 - Bleed Air System BLEED AIR FOR AIRCONDITIONING Supply Controls and indicators are located at the AIRCONDITIONING panel. Bleed-air is available when the engines are running and the BLEED push buttons are blank. When a BLEED push button is depressed to OFF, the Pressure Regulating/Shut-Off valve (PR/SO) and the HP- bleed valve close.

  • 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
