The Altostratus I is a conceptual design for a futuristic world class sailplane, designed by John McMasters.  The Altostratus was piloted by the main character of an article in Soaring Magazine, entitled "Flying the Altostratus I". The article appeared in the February, 1981 issue of Soaring, and was the chronicle of one pilot's experience piloting the Altostratus to victory in the 2001 world soaring championship.  The builders believe their's is the first demonstration that this fiction can indeed be reality in the year 2001. We look forward to updating the website as flight testing proceeds.

This Master's Project is an on-board autopilot program running on a 286 miniboard that will control a dynamic system; an aircraft in flight.  The aircraft is a 16 foot wingspan flying wing modeled on the Northrop N-9M flying wing.  Three aircraft will be built, an 11 foot testbed, a proof of concept half scale 8 foot aircraft, and the full size 16 foot wingspan aircraft with the computer on-board.  In addition to the on-board computer with an autopilot program, a modem attached to a cell phone will be used to downlink real-time telemetry to a ground computer and uplink flight commands from a ground computer.

The Flair 30 was a follow-up Flair design also developed by Günter Rochelt in 1987. The Flair 30 first flew in 1990. The pilot could launch by foot, then lay prone in a special harness, and finally land on a skid.  Presented by Stewart Midwinter.

This is a collection of a few of my favorite paper airplanes.  Much of this was developed during 5 years of sitting through French classes.  Rowin Andruscavage LEFT:  Aaron Hunt's World-Class paper glider, detailed on his web page (accessed through Rowin's).

Kasper theorized that a large vortex system, like that depicted in figure 6, was formed when the angle of attack was greater than 30 degrees.  Actually He originally thought there was only one vortex, shown rotating clockwise, but wind tunnel tests showed a secondary counter-rotating vortex as well.  He apparently thought the secondary vortex was nothing but bad news because much of His effort was directed toward diminishing it's size.  The link is a lead-in to several pages on vortex lift and stepped airfoils done by Norm Masters.

This page started as a result of Andre Petit's  irresistible pictures of Clement  Ader's  Eole.  The cyber collage at the top of  the page is a product of these pix.  The Eole was his first airplane.  He started to build a 2nd plane which he named the Avion, a word he coined as an Acronym for "Appareil Volant Imitant  les Oisaux Naturels" — Flying Machine Imitating Natural Birds. He never finished it.   Then he built a larger machine financed by the  French military , the Avion III.

These airfoils were analyzed at Reynolds numbers of 100k 200k, 400k, 600k and 2000k using XFOIL written by Prof. Mark Drela, MIT. Site by: Kelly O'Brien (kjobrien@uiuc.edu), Department of Aeronautical and Astronautical Engineering, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801

GOLDEN VALLEY, MN; An outfit called EGR Co. has put a new thrust on an old idea; deflecting the airstream from propellers to lift an aircraft vertically off the ground.  The concept dates back to the late 1950s and an experimental aircraft called the Ryan VZ-3RY. In essence, big flaps bend airflow from the propellers  downward, turning thrust into lift. But investigators found that the downward-flowing air ricocheted back into the propellers, sapping their efficiency. The bounceback also played havoc with the aircraft's horizontal tail surfaces.

Flying The Ho-IX In Late 1944. This site has some interesting articles on how the Ho IX might have been taken as a UFO due to its shape and stealth construction.  Of course, this is all speculation and should be taken as such.  The link is included since it reflects a different approach to the work of Horten.

BIRD FLIGHT The analysis of the bird flight has discovered numerous aerodynamic tricks which should be used in aircraft engineering today. These are the Multi-Winglets and the Reflux-Bags for example.  (Multi-link site covering real and model adaptations of bird wings.)

Aircraft Design Page    The Winggrid mimicks the wingtip of many birds, more obviously eagles, and results in a substantially increased lift to drag ratio. The results are so stunning that the topic is highly controversial.

Cool Web sites for Aircraft Designers This is a web site containing an extremely large number of links to other sites in a variety of subject areas, like musems, technical & professional societies, aerospace & CAD companies, government organizations, universities and resources for designers.

Airfoil Coordinates Database Version 1.0.  This is available on the Univ. of Illinois at Urbana-Champaign.  The airfoils included in this database cover a wide range of applications, from low Reynolds number airfoils for UAVs and model aircraft to jet transports. Originally this site included mostly low Reynolds number airfoils (about 160), but in December 1995 the site was greatly expanded when David Lednicer of Analytical Methods, Inc. contributed his airfoil collection. This addition brought the total number of airfoils to over 1000. More airfoils will be added as they become available.  Access at: opus.aae.uiuc.edu/~selig/ads.html

NASA's Dryden Flight Research Center web site contains a large gallery of photos and technical material on most of the aircraft that have passed through that facility over the years.  The X-33 is one of those that is looking to the future.  If you haven't visited this site before, make sure you click here and spend some time browsing around this facinating arena.

Welcome to the home page of the model aeroplane club Concorde 2000 VZW! The club is located in Herselt, Belgium (and for those from far away), Europe. The main purpose of these pages is to exchange information related to R/C Air between clubs and individuals. The Internet made the world rather small, and gives us the opportunity to share all kind of information with people from all around the world.

This is a link to the San Diego Chapter 14 EAA home page.  There are a lot of things on this page, but of particular interest is the Newsletter section and the Computer Corner prepared by Rik Keller.  He takes a simple approach to each of the subject areas so the average builder can use the material without any difficulty.  He also includes some downloadable files of Excel spreadsheets you can use for performing design calculations and performance evaluations.

This is an extensive page titled Secret Weapons of the Luftwaffe sponsored by Djordje Nikolic.  It has extensive links to many other sites and pictures of aircraft associated with the Luftwaffe, including Lippisch.  Only some flying wing material, but worth a look see for all of the other historical aircraft of the German designers.

Air mobility requirements in 2025 will demand a substantial increase from existing airship capabilities. These include a 500-ton useful lift capability, maximum airspeed of 250 knots, maximum range at maximum gross weight of 12,500 miles, and a defensive/stealth capability. Although substantially slower, the airlift capacity of this notional airship would be nearly six times that of our largest airlift platform, the C­5B.  This site also has information on other unusual shaped aircraft for the future.  Source (of drawing): William J. White, Airships for the Future (New York: Sterling Publishing Co., 1978): 127.

Bel Geddes #4 - A Fine Road Not Taken     Norman Bel Geddes was an industrial  designer who flourished between the wars. In 1929 he proposed the Airliner Number 4 as the transatlantic airliner of 1940.  It occupied a chapter of Horizons. Bel Geddes  was much impressed by the Dornier DO-X and was convinced that size was the key to safety and steamshiplike comfort.   He designed it with the help of Doctor O.A. Koller who, I read, "was responsible for  the design of over two hundred different airplanes, including the famous Phalz plane used so extensively by Germany during  WWI.......without exception all his planes have flown successfully ."

VKA-23 1960 design...Credit: © Mark Wade, 1999.     Class: Manned. Type: Spaceplane. Nation: Russia. Manufacturer: Myasishchev. Craft. Crew Size: 1. Total Length: 9.0 m. Maximum Diameter: 2.0m. Total Mass: 3,600 kg. Total Payload: 700 kg. Total Propellants: 600 kg. Total spacecraft delta v: 540 m/s. Electrical System: Batteries.  Following the very critical review of the first M-48 spaceplane design by the expert commission, Myasishchev went back to the drawing board. In March to September 1960 this work resulted in definition of two alternative configurations.  The second Myasishchev VKA-23 design was an elegant-looking, porpoise-fuselaged winged vehicle, similar to Japan's HOPE design of forty years later.
