In the early 1950s, the British Admiralty issued Naval Air Staff Target NAST 39, which laid out the service's requirements for a two-seat, carrier-based attack bomber for service at the end of the decade. Short Brothers and Harland became invoved with M.146T at the instigation of the firm's chief test pilot, Tom Brooke-Smith. Brooke-Smith pointed out that the firm's ongoing research into improving the handling of high-speed wing shapes at low speeds and altitudes might give the firm considerable advantages in the M.146T contest, given the awkward combination of high weights, short take-off and landing distances, and high-speed, low gust-response aerodynamics that the specification demanded. Hill's answer to this problem was twofold: an "aero-isoclinic" wing designed to flex in ways that enhanced stability and controllability and "tip controllers," all-moving wingtips that offered greater control power than conventional ailerons. Hill's ideas seemed to have merit when tested in the Short SB.1 glider and SB.4 Sherpa jet research aircraft. |

The Future Aircraft Technology Enhancements (FATE) Program was sponsored by Wright Laboratory (WL) FI in Dayton, Ohio, and originally led by Captain Mark Cherry, the program manager. Captain Cherry subsequently was replaced by a new program manager Mr. Tom Black, who also serves as chief engineer. Program tasks were authorized and performed under Contract No. F33615-97-C-3804 from June through October 1997. |

A simple means of obtaining a positive value of Cm0 is to choose an airfoil section with negative camber or with reflex. But there is a good reason that most airfoils have negative pitching moments: concentrating most of the lift forward of the airfoil's 1/4 chord point results in long, adverse pressure gradients with correspondingly low CLmax and only short stretches of laminar flow. Some recent progress has been made in the area of low and positive moment airfoil design, but there are fundamental limits as to what may be done in this area. |

Gotha
Go 229 / Horten Ho IX The Go 229 was initially designed by the
brothers Reimar and Walter Horten, pioneers in early flying wing aircraft
designs. The Horten brothers were attempting to figure out ways to eliminate
every sourse of parasitic drag.

The
Armee de l'Air produced some interesting airplanes. I don't know
much about this one except what the 3Vu shows. I remember pictures
of a lightweight French airplane with a similar planform. But I am about
positive this qualifies as a fantasy airplane. Maybe the French released
the plan to give the Germans something to worry about. In any case
you have a genuine period 3vu to show a skeptical CD.
If anyone knows more about this I'd sure like to here from them. Write me at... dannysoar@worldnet.att.net The drawing is from the September '39 Flying Aces. |

FLYING WING PROJECTS OF THE 30S, By Hanspeter Dabrowski
Horten aircraft almost always consist of wings only, i.e. they are planes without fuselage or vertical steering and stabilising elements as opposed to Alexander Lippisch's tailless planes. However, it was the later who inspired the Horten Brothers Reimar (1915-1993) and Walter (1913-1998) to take up their flying wing model experiments at the beginning of the 1930s. The two brothers started to build their first glider, which was large enough to carry a human being, in their parents' flat. The flying wing known as the H I had a wing span of 12.4 meters and was test flown by Walter Horten on the Bonn- Hangelar Airport in July 1933. |

The Facetmobile
is an experimental lifting-body sport airplane. It was built by Barnaby
Wainfan, Rick Dean, and Lynne Wainfan to explore the characteristics and
potential of this type of airplane.
The configuration was developed using a combination of analytical methods, radio-controlled model testing and wind-tunnel testing. In all, 8 radio-controlled models were built and flown. Construction of N117WD took 2 1/2 years. First flight was April 22, 1993. Total flight time to date is approximately 130 hours. No plans or kits are currently being offered. |

William
Horton had a dream, the "wingless
airplane". Instead of a long high aspect ratio wing the fuselage was
to create the lift and tip plates which he called "sealers" were to prevent
the high tip losses that otherwise plague such airfoils.
Horton had designed the airplane in the early 1950s but didn't have the money to develop it. He then was able to get into a partnership with Howard Hughes and Harlow Curtis, since Hughes obviously had the money for producing the plane. The venture failed not because the airplane didn't fly, but because Hughes wanted to take full credit for the patents and production rights, which Horton refused to do. |

Did you know that there are only three of Jack Northrop’s "Flying Wings"
known to be left in the world? The Western
Museum of Flight is extremely fortunate to have one of them, the Northrop
JB-1 "Bat". The other two are the Northrop N-1M at the Smithsonian National
Air and Space Museum, Washington, D.C., and the beautifully restored Northrop
N-9MB at the "Planes of Fame Museum," Chino, California.
During June 1996, the Western Museum of Flight’s JB-1 restoration team consisting of Rick Hilton, Alex Von Tol, and Fred Erb lovingly restored the Northrop JB-1 "Bat." |
