NASA RESEARCH ON FLEXIBLE WINGS By Francis M. Rogallo NASA Langley Research Center SUMMARY Flexible wings are wings made of very loose or slack cloth whose configu- ration in flight is maintained by the combination of the aerodynamic forces and the reactions from the load suspension system. Such wings can be completely flexible_ or they may be stiffened in several ways to meet the requirements of particular applications. Wing planforms and the geometry of the load suspension system are also subject to wide variations. The overall spectrum of flexible wings investigated at the Langley Research Center is presented and the state of the art with regard to maximum lift-drag ratios obtained is defined for a wide range of wing configurations. Maximum lift-drag ratios above 3.0 were obtained on completely flexible wings; and for cylindrical-type flexible wings, values of lift-drag ratios up to 17.0 were obtained when the wing had small, tapered rigid leading edges. The flexible wings of most immediate interest are those with no structural stiffening because they have weight, volume, packing, and deployment character- istics potentially as good as those of conventional parachutes, but provide a stable and controllable glide with performance adequate for aerial delivery of cargo and personnel, for landing space capsules, boosters, or hypersonic air- craft, and as emergency wings for aircraft or aircraft escape systems. -
Module-7 Lecture-29 Flight Experiment
Module-7 Lecture-29 Flight Experiment: Instruments used in flight experiment, pre and post flight measurement of aircraft c.g. Module Agenda • Instruments used in flight experiments. • Pre and post flight measurement of center of gravity. • Experimental procedure for the following experiments. (a) Cruise Performance: Estimation of profile Drag coefficient (CDo ) and Os- walds efficiency (e) of an aircraft from experimental data obtained during steady and level flight. (b) Climb Performance: Estimation of Rate of Climb RC and Absolute and Service Ceiling from experimental data obtained during steady climb flight (c) Estimation of stick free and fixed neutral and maneuvering point using flight data. (d) Static lateral-directional stability tests. (e) Phugoid demonstration (f) Dutch roll demonstration 1 Instruments used for experiments1 1. Airspeed Indicator: The airspeed indicator shows the aircraft's speed (usually in knots ) relative to the surrounding air. It works by measuring the ram-air pressure in the aircraft's Pitot tube. The indicated airspeed must be corrected for air density (which varies with altitude, temperature and humidity) in order to obtain the true airspeed, and for wind conditions in order to obtain the speed over the ground. 2. Attitude Indicator: The attitude indicator (also known as an artificial horizon) shows the aircraft's relation to the horizon. From this the pilot can tell whether the wings are level and if the aircraft nose is pointing above or below the horizon. This is a primary instrument for instrument flight and is also useful in conditions of poor visibility. Pilots are trained to use other instruments in combination should this instrument or its power fail. -
How to Make My Air Glide S Work Properly
How to make my Air Glide S work properly Originally written by Horst Rupp. Many thanks to Richard Frawley who edited and retranslated this article into proper English. 2014/11/21. The basic prerequisite for the Air Glide S, in particular the AHRS part, to work properly so that the extraneous ‘noise’ (gusts, wind shifts, perturbations etc) can be removed is to ensure that it is set up correctly. The instrument is very sensitive and the installation needs to be done in a way that ensures that only the correct inputs are being sensed. Most legacy instrument installations take all pressures from probes at the rudder fin. And most unfortunately, many of them use the total energy (TE) pressure from the fin to feed in parallel a mass-measurement variometer with a capacity flask (in Germany mostly a Winter) and a pressure sensor probe variometer such as the Air Glide S (no capacity flask). There are many publications indicating the deterioration (mostly damping) of the pressure sensor probe measurements by the stream of air mass in and out of the capacity flask. So, it is obviously a somewhat bad idea to do that to your Air Glide S. This interference with a mass measuring instruments is certainly not compliant with the above mentioned basic prerequisite. Fortunately, the Air Glide S can be compensated by total pressure (called electronic compensation as opposed to TE compensation). This is a new feature of the Air Glide S arriving with V 1.1. Total pressure and TE pressure carry more or less (depends on quality of probe) the same information - but for the sign : Total pressure is static pressure PLUS pitot pressure, TE pressure is static pressure MINUS pitot pressure (probe compensation factor (~)-1). -

Study of the Pilot's Attention in the Cabin During the Flight Auxiliary Devices Such As Variometer, Turn Indicator with Crosswise Or Other
Journal of KONES Powertrain and Transport, Vol. 25, No. 3 2018 ISSN: 1231-4005 e-ISSN: 2354-0133 DOI: 10.5604/01.3001.0012.4309 STUDY OF THE PILOT’S ATTENTION IN THE CABIN DURING THE FLIGHT Mirosław Adamski, Mariusz Adamski, Ariel Adamski Polish Air Force Academy, Department of Aviation Dywizjonu 303 Street 35, 08-521 Deblin, Poland tel.: +48 261 517423, fax: +48 261 517421 e-mail: [email protected] [email protected], [email protected] Andrzej Szelmanowski Air Force Institute of Technology Ksiecia Boleslawa Street 6, 01-494 Warsaw, Poland tel.: +48 261 851603, fax: +48 261 851646 e-mail: [email protected] Abstract The pilot, while performing certain tasks or being in the battlefield environment works in a time lag. He is forced to properly interpret the information and quickly and correctly take action. Therefore, the instruments in the cabin should be arranged in such a way that they are legible and the operator have always-easy access to them. Due to the dynamics of the aircraft and the time needed to process the information by the pilot, a reaction delay occurs, resulting in the plane flying in an uncontrolled manner even up to several hundred meters. This article discusses the VFR and IFR flight characteristics, the pilot’s attention during flight, cabin ergonomics, and the placement of on-board instruments having a significant impact on the safety of the task performed in the air. In addition, tests have been carried out to determine exactly what the pilot’s eye is aimed at while completing the aerial task. -
TOTAL ENERGY COMPENSATION in PRACTICE by Rudolph Brozel ILEC Gmbh Bayreuth, Germany, September 1985 Edited by Thomas Knauff, & Dave Nadler April, 2002
TOTAL ENERGY COMPENSATION IN PRACTICE by Rudolph Brozel ILEC GmbH Bayreuth, Germany, September 1985 Edited by Thomas Knauff, & Dave Nadler April, 2002 This article is copyright protected © ILEC GmbH, all rights reserved. Reproduction with the approval of ILEC GmbH only. FORWARD Rudolf Brozel and Juergen Schindler founded ILEC in 1981. Rudolf Brozel was the original designer of ILEC variometer systems and total energy probes. Sadly, Rudolph Brozel passed away in 1998. ILEC instruments and probes are the result of extensive testing over many years. More than 6,000 pilots around the world now use ILEC total energy probes. ILEC variometers are the variometer of choice of many pilots, for both competition and club use. Current ILEC variometers include the SC7 basic variometer, the SB9 backup variometer, and the SN10 flight computer. INTRODUCTION The following article is a summary of conclusions drawn from theoretical work over several years, including wind tunnel experiments and in-flight measurements. This research helps to explain the differences between the real response of a total energy variometer and what a soaring pilot would prefer, or the ideal behaviour. This article will help glider pilots better understand the response of the variometer, and also aid in improving an existing system. You will understand the semi-technical information better after you read the following article the second or third time. THE INFLUENCE OF ACCELERATION ON THE SINK RATE OF A SAILPLANE AND ON THE INDICATION OF THE VARIOMETER. Astute pilots may have noticed when they perform a normal pull-up manoeuvre, as they might to enter a thermal; the TE (total energy) variometer first indicates a down reading, whereas the non-compensated variometer would rapidly go to the positive stop. -

Jet Ski for the Song of the Same Name by Bikini Kill, See Reject All American. Jet Ski Is the Brand Name of a Personal Watercraf
Jet Ski From Wikipedia, the free encyclopedia (Redirected from Jet skiing) For the song of the same name by Bikini Kill, see Reject All American. European Personal Watercraft Championship in Crikvenica Waverunner in Japan Racing scene at the German Championship 2007 Jet Ski is the brand name of a personal watercraft manufactured by Kawasaki Heavy Industries. The name is sometimes mistakenly used by those unfamiliar with the personal watercraft industry to refer to any type of personal watercraft; however, the name is a valid trademark registered with the United States Patent and Trademark Office, and in many other countries.[1] The term "Jet Ski" (or JetSki, often shortened to "Ski"[2]) is often mis-applied to all personal watercraft with pivoting handlepoles manipulated by a standing rider; these are properly known as "stand-up PWCs." The term is often mistakenly used when referring to WaveRunners, but WaveRunner is actually the name of the Yamaha line of sit-down PWCs, whereas "Jet Ski" refers to the Kawasaki line. [3] [4] Recently, a third type has also appeared, where the driver sits in the seiza position. This type has been pioneered by Silveira Customswith their "Samba".
