User Manual ATOS C Version: 29.01.2002 English translation: 9 August 2002 by Heiner Biesel Please read before flying! Congratulations on your purchase, and welcome to the ATOS world! Your ATOS C is a high performance glider. To fully exploit its capabilities while remaining well within safe limits, you should become thoroughly familiar with the contents of this manual. If you have any questions or need support, do not hesitate to contact the A.I.R. Team. Your A.I.R. Team Version: 01/02 1 1. Transport • By car The carbon fiber D-tube can be damaged by point loading. For safe transport the glider should always be supported by a large padded area. A ladder with several padded steps is one possibility. If the D- tube is supported at only two places, these supports need to be padded at least 4 inches in length, and wide enough to support the full width of the glider. Anything less is likely to result in transport damage, which can seriously reduce the strength of the main spar and the entire D-tube. Do not tie down the glider too tightly, and use wide tubular of flat webbing to minimize point loading. If the glider is likely to get exposed to rain, and especially to salt water, a watertight cover bag is strongly recommended. If the ATOS C gets wet, dry it as quickly as possible to avoid staining the sail, or causing corrosion of the metal parts. Exposure to salt water should always be followed by a thorough rinse in sweet water. -

Static and Dynamic Performance of a Morphing Trailing Edge Concept with High-Damping Elastomeric Skin

Received: 18 November 2018; Accepted: 14 February 2019; Published: 19 February 2019 Abstract: Nature has many striking examples of adaptive structures: the emulation of birds’ flight is the true challenge of a morphing wing. The integration of increasingly innovative technologies, such as reliable kinematic mechanisms, embedded servo-actuation and smart materials systems, enables us to realize new structural systems fully compatible with the more and more stringent airworthiness requirements. In this paper, the authors describe the characterization of an adaptive structure, representative of a wing trailing edge, consisting of a finger-like rib mechanism with a highly deformable skin, which comprises both soft and stiff parts. The morphing skin is able to follow the trailing edge movement under repeated cycles, while being stiff enough to preserve its shape under aerodynamic loads and adequately pliable to minimize the actuation power required for morphing. -

11ADOBL04 December 2010
11ADOBL04 December 2010 Use of rudder on Airbus A300-600/A310 (extracted from former FCOM Bulletin N°15/1 – Subject N°40) Reason for issue On February 8th, 2002, the National Transportation Safety Board (NTSB), in cooperation with the French Bureau d'Enquêtes et d'Analyses (BEA), issued recommendations that aircraft manufacturers re-emphasize the structural certification requirements for the rudder and vertical stabilizer, showing how some maneuvers can result in exceeding design lim- its and even lead to structural failure. The purpose of this Bulletin is to re-emphasize proper operational use of the rudder, highlight certification requirements and rud- der control design characteristics. Yaw control General In flight, yaw control is provided by the rudder, and directional stability is provided by the vertical stabilizer. The rudder and vertical stabilizer are sized to meet the two following objectives: Provide sufficient lateral control of the aircraft during crosswind takeoffs and landings, within the published crosswind limits (refer to FCOM Operating Limitations chapter). Provide positive aircraft control under conditions of engine failure and maximum asymmetric thrust, at any speed above Vmcg (minimum control speed - on ground). The vertical stabilizer and the rudder must be capable of generating sufficient yawing moments to maintain directional control of the aircraft. The rudder deflection, necessary to achieve these yawing moments, and the resulting sideslip angles place significant aerodynamic loads on the rudder and on the vertical stabilizer. Both are designed to sustain loads as prescribed in the JAR/FAR 25 certification requirements which define several lateral loading conditions (maneuver, gust loads and asymmetric loads due to engine failure) leading to the required level of structural strength. -

09 Stability and Control
Aircraft Design Lecture 9: Stability and Control G. Dimitriadis Introduction to Aircraft Design Stability and Control H Aircraft stability deals with the ability to keep an aircraft in the air in the chosen flight attitude. H Aircraft control deals with the ability to change the flight direction and attitude of an aircraft. H Both these issues must be investigated during the preliminary design process. Introduction to Aircraft Design Design criteria? H Stability and control are not design criteria H In other words, civil aircraft are not designed specifically for stability and control H They are designed for performance. H Once a preliminary design that meets the performance criteria is created, then its stability is assessed and its control is designed. Introduction to Aircraft Design Flight Mechanics H Stability and control are collectively referred to as flight mechanics H The study of the mechanics and dynamics of flight is the means by which : – We can design an airplane to accomplish efficiently a specific task – We can make the task of the pilot easier by ensuring good handling qualities – We can avoid unwanted or unexpected phenomena that can be encountered in flight Introduction to Aircraft Design Aircraft description Flight Control Pilot System Airplane Response Task The pilot has direct control only of the Flight Control System. However, he can tailor his inputs to the FCS by observing the airplane’s response while always keeping an eye on the task at hand.
