As the conditions were conducive to the formation of carburettor icing, with a temperature of +5°C and a dew point of +1.6°C, particular attention was paid to the use of carburettor heat during the run-up and immediately prior to take off. The engine reportedly performed normally and carburettor heat was used during the pre-landing downwind checks and again on base leg, with its selection maintained until after the glide approach and landing, in accordance with the normal operating procedure for this 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. -

Optimal Dynamic Soaring for Full Size Sailplanes
OPTIMAL DYNAMIC SOARING FOR FULL SIZE SAILPLANES THESIS Randel J.

AFIT/GAE/ENY06-S04 GAE 06S OPTIMAL DYNAMIC SOARING FOR FULL SIZE SAILPLANES THESIS Presented to the Faculty Department of Aeronautical and Astronautical Engineering Graduate School of Engineering and Management Air Force Institute of Technology Air University Air Education and Training Command In Partial Fulfillment of the Requirements for the Degree of Master of Science in Aeronautical Engineering Randel J. Gordon, BS Captain, USAF September 2006 APPROVED FOR PUBLIC RELEASE; DISTRIBUTION UNLIMITED. AFIT/GAE/ENY06-S04 GAE 06S Abstract Dynamic soaring is a unique flying technique designed to allow air vehicles to extract energy from horizontal wind shears. Dynamic soaring has been used by seabirds like the Albatross to fly hundreds of kilometers a day across the ocean. Small hobby radio controlled sailplanes have also used this technique to achieve sustained speeds of over 200 miles per hour from just a simple hand toss. Dynamic soaring, however, has never before been studied for use on full size aircraft. The primary goal of this research was to prove or disprove the viability of dynamic soaring for enhancing a full size aircraft’s total energy by using a manned sailplane as a demonstration air vehicle. -
Comparative Acoustical Characterization of Sailplane Interiors
COMPARATIVE ACOUSTICAL CHARACTERIZATION OF SAILPLANE INTERIORS Jurica Ivošević1, Dubravko Miljković2, Tino Bucak1 1University of Zagreb, Faculty of Transport and Traffic Sciences, Department of Aeronautics, Vukelićeva 4, Zagreb, Croatia; 2HEP Zagreb, Croatia [email protected], [email protected], [email protected] Abstract: Aircraft interior noise of small engine powered aircraft and their comparison have been investigated by many researchers. This paper deals with a glider aircraft that, after being launched by towing aircraft, continues an autonomous, non-powered soaring flight. The interior noise is predominantly generated aerodynamically by wind slipstream during progressive flight. A number of interior noise measurements have been undertaken on two different types of glider aircraft, Schleicher K7 Rhönadler and Blanik L-13, at different phases of flight with various speeds and wing control surface configurations and some of the results will be presented and discussed. Key words: sailplane, glider, interior, acoustics, noise 1. INTRODUCTION 1.1. Sources of sailplane noise This paper focuses on the comparative acoustical The noise of small engine powered aircraft usually characterization of the interiors of two different types of consists of two major components: powerplant noise glider aircraft, Schleicher K7 Rhönadler and Blanik (engine, exhaust and propeller noise) and aerodynamic L-13, both being used for flight training and operated by (airframe) noise, [1]. In addition to the airframe noise and Aeroklub Zagreb. This contribution to the overall noise structure borne noise present during autonomous flight, image of sailplanes interior should be known, as those noise in a sailplane during a towing phase originates also findings can be used to control and minimize the noise from the towing aircraft (engine, propeller and exhaust effects on crew. -

Report from World Soaring Championships Trophies Manager to the IGC 2012 Plenary
January 2012 Report from World Soaring Championships Trophies Manager to the IGC 2012 Plenary Author: Marina Vigorito The document has been updated with the names of the 2011 Champions. Unfortunately we ignore the history of the Club Class Trophy. I didn’t find anybody that remembers anything about it. I’m still working on the Team Cup for the Juniors WGC and I am very much confident that the Polish Organisers will meet my expectation. Once again, I’m very much sorry to notify that some trophies were delivered without the names of the winners engraved, despite my recommendations. It’s going to be a very frequent practice, which is far from our traditions and from the spirit of the trophies. We should consider adding in the Annex A a paragraph about this requirement. In order to avoid any misunderstanding and disappointments, I would like to make clear that the 32nd World Championship is one, held in two different locations to accommodate six classes. The World Soaring Cup will be consequently awarded in Argentina, not in Uvalde, taking into account the cumulative scores of the two events. In 2012 we will have the last World Class world championships and after the two years in the hand of the winner, I propose to retain the Trophy in the FAI head office of Lausanne, as enduring remembrance for all the people that devoted so much of their time and effort to this project. In 2014 we will have our first 20m Class world championship. The Finnish NAC has generously offered a trophy for this class, dedicated to Mr. -
