Use of Rudder on Boeing Aircraft
12ADOBL02 December 2011 Use of rudder on Boeing aircraft According to Boeing the Primary uses for rudder input are in crosswind operations, directional control on takeoff or roll out and in the event of engine failure. This Briefing Leaflet was produced in co-operation with Boeing and supersedes the IFALPA document 03SAB001 and applies to all models of the following Boeing aircraft: 707, 717, 727, 737, 747, 757, 767, 777, 787, DC-8, DC-9, DC-10, MD-10, md-11, MD-80, MD-90 Sideslip Angle Fig 1: Rudder induced sideslip Background As part of the investigation of the American Airlines Flt 587 crash on Heading Long Island, USA the United States National Transportation Safety Board (NTSB) issued a safety recommendation letter which called Flight path for pilots to be made aware that the use of “sequential full opposite rudder inputs can potentially lead to structural loads that exceed those addressed by the requirements of certification”. Aircraft are designed and tested based on certain assumptions of how pilots will use the rudder. These assumptions drive the FAA/EASA, and other certifica- tion bodies, requirements. Consequently, this type of structural failure is rare (with only one event over more than 45 years). However, this information about the characteristics of Boeing aircraft performance in usual circumstances may prove useful. Rudder manoeuvring considerations At the outset it is a good idea to review and consider the rudder and it’s aerodynamic effects. Jet transport aircraft, especially those with wing mounted engines, have large and powerful rudders these are neces- sary to provide sufficient directional control of asymmetric thrust after an engine failure on take-off and provide suitable crosswind capability for both take-off and landing. -
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. -

Glider Handbook, Chapter 2: Components and Systems
Chapter 2 Components and Systems Introduction Although gliders come in an array of shapes and sizes, the basic design features of most gliders are fundamentally the same. All gliders conform to the aerodynamic principles that make flight possible. When air flows over the wings of a glider, the wings produce a force called lift that allows the aircraft to stay aloft. Glider wings are designed to produce maximum lift with minimum drag. 2-1 Glider Design With each generation of new materials and development and improvements in aerodynamics, the performance of gliders The earlier gliders were made mainly of wood with metal has increased. One measure of performance is glide ratio. A fastenings, stays, and control cables. Subsequent designs glide ratio of 30:1 means that in smooth air a glider can travel led to a fuselage made of fabric-covered steel tubing forward 30 feet while only losing 1 foot of altitude. Glide glued to wood and fabric wings for lightness and strength. ratio is discussed further in Chapter 5, Glider Performance. New materials, such as carbon fiber, fiberglass, glass reinforced plastic (GRP), and Kevlar® are now being used Due to the critical role that aerodynamic efficiency plays in to developed stronger and lighter gliders. Modern gliders the performance of a glider, gliders often have aerodynamic are usually designed by computer-aided software to increase features seldom found in other aircraft. The wings of a modern performance. The first glider to use fiberglass extensively racing glider have a specially designed low-drag laminar flow was the Akaflieg Stuttgart FS-24 Phönix, which first flew airfoil. -

Efficient Light Aircraft Design – Options from Gliding
Efficient Light Aircraft Design – Options from Gliding Howard Torode Member of General Aviation Group and Chairman BGA Technical Committee Presentation Aims • Recognise the convergence of interest between ultra-lights and sailplanes • Draw on experiences of sailplane designers in pursuit of higher aerodynamic performance. • Review several feature of current sailplanes that might be of wider use. • Review the future for the recreational aeroplane. Lift occurs in localised areas A glider needs efficiency and manoeuvrability Drag contributions for a glider Drag at low speed dominated by Induced drag (due to lift) Drag at high ASW-27 speeds Glider (total) drag polar dominated by profile drag & skin friction So what are the configuration parameters? - Low profile drag: Wing section design is key - Low skin friction: maximise laminar areas - Low induced drag – higher efficiencies demand greater spans, span efficiency and Aspect Ratio - Low parasitic drag – reduce excrescences such as: undercarriage, discontinuities of line and no leaks/gaps. - Low trim drag – small tails with efficient surface coupled with low stability for frequent speed changing. - Wide load carrying capacity in terms of pilot weight and water ballast Progress in aerodynamic efficiency 1933 - 2010 1957: Phoenix (16m) 1971: Nimbus 2 (20.3m) 2003: Eta (30.8m) 2010: Concordia (28m) 1937: Wiehe (18m) Wooden gliders Metal gliders Composite gliders In praise of Aspect Ratio • Basic drag equation in in non-dimensional, coefficient terms: • For an aircraft of a given scale, aspect ratio is the single overall configuration parameter that has direct leverage on performance. Induced drag - the primary contribution to drag at low speed, is inversely proportional to aspect ratio • An efficient wing is a key driver in optimising favourable design trades in other aspects of performance such as wing loading and cruise performance. -

The controller asymptotically tracks a time-parameterized position reference, and depends on an orientation look-up rule to detemine the vehicle orientation from a desired acceleration. A coordinated-flight look-up rule compatible with the controller provides a nominal level of capability for traditional flight trajec- tories. A generalized coordinated look-up rule compatible with the controller provides more advanced capability, including stability for high angle of attack and hovering maneuvers, at the expense of an additional requirement from the reference trajectory. Basic simulation results are used to verify the controller, and a simulation software framework is described which will enable more extensive simulation and provide a platform for the final controller implementation. -

Abstract The effects of wing loading on the design of short takeoff and landing (STOL) transports using (1) mechanical flap systems, and (2) externally blown flap systems are determined. Aircraft incorporating each high-lift method are sized for Federal Aviation Regulation (F.A.R.) field lengths of 2,000 feet, 2,500 feet, and 3,500 feet, and for payloads of 40, 150, and 300 passengers, for a total of 18 point-design aircraft.
