Barnes Wallis
'An Introduction To The Work of A Genius' by Ian Bayley. Brief biography, with photographs.Category Regional Europe Scientists Wallis, Sir Barnes Neville If his designs for a 'variable geometry' aircraft were continued Britain couldhave led the world in aircraft design but funds were not available.

Extractions: by Ian Bayley Barnes Wallis is one of Britain's great unsung heroes. Should his name be recollected at all it is usually associated with the bouncing bomb of world war two fame and then promptly forgotten. Yet this man whose life spanned from the early days of flight to the advanced jet engine had a gift of inventiveness coupled with design that was nothing short of genius. It is unfortunate that due to political wrangling, economic problems and a little bad luck he never received the recognition he deserved outside of a small group in the aeronautical industry. Born in 1887 of a middle class yet hard-up family, Barnes Neville Wallis was sixteen when the Wright Brothers made their first successful flight on 17th December 1903. This was not something that particularly attracted his attention and he left school in 1904 with little in the way of qualifications and no job. After an apprenticeship at an engineering company followed by work at a shipyard on the Isle of Wight Barnes finally came into contact with airships and on 1st September 1913 attained the post of Chief Assistant in the Vickers Airship Department. Although he was to remain surprisingly loyal to Vickers over the years to come, it was here that he encountered the political wrangling and government interference that was to frequently frustrate him. The R100 Airship - Built using a geodetic design Despite many obstacles, including several periods of unemployment, Barnes brought a fresh and unique approach to airship design. First by creating the R80 and then by producing the R100 which used geodetic principles in its production. These airships were unlike any others created but due to political reasons Barnes was to suffer the disappointment of seeing both of these unique craft scrapped within months of their launch

Extractions: Revision Date: 12/17/1999 Lockheed Martin Tactical Aircraft Systems (LMTAS) has developed a Fuel System Simulator (FSS) as an important tool in conducting aircraft fuel systems testing. Innovative design and fabrication procedures used in the design and building of simulated fuel tanks for the F-22 FSS are helping improve quality and lower program costs. The FSS facilitates comprehensive systems level testing early in a development program and at a lower cost than conducting testing on a ground or flight test aircraft. The test article includes a shipset of actual aircraft plumbing such as pumps, valves, tubing and instrumentation. This plumbing is installed into a set of full-scale, simulated fuel tanks and monitored and controlled with aircraft processors and software. Test equipment is provided at the FSS to simulate aircraft ground and in-flight environments and other parameters that impact the operation of the fuel system. Equipment is also provided to allow in-flight and ground refuel testing and defueling. This FSS test equipment provides test conditions and allows the aircraft hardware and controls to respond to those conditions in a laboratory environment.

Extractions: Sensor Placement Visualization M any modern military aircraft are often fielded with several wide field of view sensors. Most often these sensors are related to the missile warning system for detection of incoming threats. Thus, in order to detect threats from any direction, it is desired to place these sensors in a method that will provide full four Pi steradian coverage. Unfortunately, placement is limited by such considerations as flexure, vibration, airflow, and cable lengths. Also, the view of a particular sensor may be obscured other aircraft parts such as wings, fins, and pylons. These factors reduce an individuals ability to comprehend the coverage of a multi-sensor placement on a complex aircraft. T his project allows the user to interactively place multiple sensors on a three dimensional aircraft model. The software creates images of the aircraft from these sensor locations for viewing obscuration effect. These obscuration maps are also used in the projection of the view frustum onto a sphere. The field of view is also projected onto a Mercator plot for quick view of multiple sensor coverage. Synopsis Sensor Placement Obscuration Mercator Plot ...

Extractions: About the author, Chris Heintz Aeronautical engineer Chris Heintz, the designer of Zenith Aircraft Company's line of kit aircraft, is one of the most qualified and knowledgable light aircraft designers today. With prior experience from Aerospatiale, de Havilland, and Avions Robin (France), Heintz has designed and introduced more than 12 successful kit aircraft designs. Recently, the ZENITH CH 2000 design was put into production as a standard FAA type-certificated production aircraft. Heintz regularly shares his design and construction expertise as a speaker to aviation groups and students of aeronautical engineering, and is a regular speaker at both the EAA Oshkosh and Sun'n Fun fly-in conventions. An aeronautical engineer, Heintz has the unique ability of being able to simplify design concepts and to clearly explain and illustrate light aircraft design and construction. Chris Heintz' articles were published in the Experimental Aircraft Association's (EAA) Light Plane World or Experimenter publications. By Chris Heintz Part 1 We have to keep in mind that the airfoil of our flying surfaces is only one variable of the many components which makes our airplanes fly well - or not so well - in a range of possible configurations. When we do an investigation of any part of our aircraft we must not look at this part as THE solution, rather we must always remember that it is only one part of a whole. Analysis is necessary; but only a synthetic view will give us the whole picture. It is a bit like somebody trying to understand the human body by studying the skeleton only, or the chemicals of the body only, etc.: the failure of modern medicine comes from this fact. Scientists look at the parts of a corpse and decide they know something about a living body!

Extractions: Co-Investigators: Ken Gee (MCAT), Ferhat Hatay(MCAT), Jahed Djomehri(CALSPAN) The objective of this work is to integrate an overset Navier-Stokes flow solver with a modal structural code to computationally determine the effects of aeroelasticity on the aerodynamic characteristics of aircraft using massively parallel computers. A modal structural code was integrated into the OVERFLOW code, which solves the Navier-Stokes flow equations using overset grids to model the geometry. The initial development centered on the PVM version of the parallel OVERFLOW code. With the development of an MPI version of OVERFLOW, an MPI version of the aeroelastic code was developed as well. Arrow-wing-body tip deflection convergence history. A new MPI version of a parallel, overset, aeroelastic code (OVERAERO) was developed based on the OVERFLOW and modal structures codes. The OVERAERO code can compute the aeroelastic deformation of a surface due to the aerodynamic loads generated by the surface. Multiple structural surfaces can be computed for a given geometry, each with its own modal data set. Rigid structures attached to a flexible surface, such as a nacelle attached to a wing, are moved according to the deflection of the attachment region on the flexible surface. Flexible surfaces, for which no modal data are available, such as a slat or flap attached to a wing, can be deflected by assuming the deformation mirrors the wing deformation.

http://wright.nasa.gov/airplane/geom.html

Extractions: This slide gives technical definitions of a wing's geometry, which is one of the chief factors affecting airplane lift and drag. The terminology used here is used throughout the airplane industry today and was mostly known to the Wright brothers in 1900. Actual aircraft wings are complex three-dimensional objects, but we will start with some simple definitions. The figure shows a wing viewed from three directions; the upper left shows the view from the top looking down on the wing, the lower left shows the view from the front looking at the wing leading edge, and the right shows a side view from the left looking in towards the centerline. The side view shows an airfoil shape with the leading edge to the left. This airfoil is a modern, thick airfoil, which is slightly different from the thin airfoils used by the Wrights and shown below. The terminology, however, is the same. Top View The top view shows a simple rectangular wing geometry, like that used by the Wright brothers. The front of the wing (at the bottom) is called the leading edge ; the back of the wing (at the top) is called the trailing edge . The distance from the leading to trailing edges is called the chord . The ends of the wing are called the wing tips , and the distance from one wing tip to the other is called the span . The shape of the wing, when viewed from above looking down onto the wing, is called a

http://www.authrustersupport.aunz.com/records/tosgadvicet300geom.html

Extractions: We had a T300 (a very fast one) in recently which we ultimately found had a major basic aerodynamic problem with it - stemming back to a substantial rebuild occasioned by an equally substantial prang following an engine failure. The research which went into tracking down what proved to be a serious and complex problem took some time, both in the air and on the ground - so is worth giving some space to. The aircraft looked like a million bucks and no expense had been knowingly spared on the re-build and subsequent `smoothing'. The owner had been in repeated contact with me regarding a roll problem - which I understood had been fixed - and ultimately I ended up doing a reasonably long distance ferry flight as part of the connection process between previous and new owners. During the ferry I was not entirely happy with the aircraft. A roll problem still existed now and then but the aircraft would fly very comfortably `hands off' at cruising speed. The aircraft carried a `NavMan' fuel monitoring system and I had difficulty keeping fuel consumption on the 582 below 21 litres per hour and not infrequently saw 24 ltrs/hr on the clock. O.K. we were going fast but the engine certainly appeared to be working harder than the particular configuration of the aircraft would suggest should be the case. This ferry flight was not one of the better ones due to a howling head wind and my unknowingly still having my previous virus problem which came back claws and all in the totally enclosed and consequently very hot cockpit. I had Joe Mikus with me and he ended up doing most of the flying while I steamed in the corner for much of the three and a half hour flight.
3.0 ANALYSIS TOOLS

Extractions: 3.0 ANALYSIS TOOLS 3.0 ANALYSIS TOOLS Sections-4 and 5 of this report employ the everyday tools of mathematics and physics. However, they also apply other methods. These include methods for 1) locating the aircraft, 2) locating the sun, and 3) understanding sun reflections. To understand Sections-4 and 5, it's important to provide a brief discussion of these three areas before proceeding. The section begins by discussing aircraft location. Locating the Aircraft Locating the Sun Similarly, the position of the sun is also known. Computer programs generate the sun's azimuth and elevation angle when supplied with a location, date, and time of day. The program used in this analysis comes from the United States Naval Observatory (USNO) via the Internet. The URL is: http://aa.usno.navy.mil/AA/data/ This address provides access to a page called "Data On-Line" which contains "Positions of the Sun and Moon." The program generates solar azimuth/elevation angle data at one-minute intervals for present, future, and past dates. It contains its own city coordinate file and Waco is the closest stored city location. Mt. Carmel is sufficiently near Waco to cause only small, acceptable errors in solar azimuth and elevation angle values. This was determined through an error analysis of sun position data generated by the program for nearly co-located city pairs in other areas.
