Schempp-Hirth Mini-Moazagotl / Minimoa Goppingen GÖ-3

In 1938 the company moved to Kirchheim/Teck and employed more than 300 people during the war time.
The first serial gliders were the aerobatic single seat trainer GÖ-1 ‘Wolf’ from Wolf Hirth and the renown GÖ-3 ‘Minimoa’ as well as the two seat GÖ-4 from Wolfgang Hütter.
One of Germany’s leading high performance single seaters before the war, this gull-winged glider was designed by two of Germany’s leading sailplane pilots, Martin Schempp and Wolf Hirth. They designed and developed the Minimoa from the 20m span Moazagotl, and the name Minimoa is a contraction of miniature Moazagotl, although the design was also known as the Goppingen 3.

In its original form it had cantilever shoulder-mounted gull wings, and it was built by Wolf Hirth and Dipl-lng Wolfgang Mutter. Of conventional wood and fabric construction, the Minimoa is characterised by swept back wing outer panel leading edges and large ailerons with trailing edges projecting beyond those of the wing itself; air brakes of the same basic Schempp-Hirth type later to be featured on many other sailplanes are fitted. The tailplane is mounted ahead of the fin and is raised above the fuselage top line. The pilot sits under a one-piece hinged cockpit canopy that opens to starboard, and by prewar standards the cockpit was roomy. Landing gear consists of a non-retractable monowheel and a skid under the nose, plus a small tailskid. By 1938 the Minimoa 3B was introduced with the gull wings now in the mid position with a modified aerofoil section, and reduced weight. From July 1935 to 1939 a total of 110 Minimoas were built, of which 13 were sold abroad to Britain, France, the USA, Argentina, South Africa and Japan; a few survived the war and are still flying.

First flown in 1935, the Minimoa made its mark in contest flying, taking third place at the 1937 International Competition at the Wasserkuppe in Germany flown by Wolfgang Spate. Richard du Pont and Chet Decker flew Minimoas to win the U.S. Championships in 1937 and 1939. The Minimoa established a number of records, including the world altitude record in 1938 (using lift in cumulo nimbus cloud) of 6,687 m/ 21,939 ft. The name was an abbreviation of its original nickname, Mini- Moazagotl, as it was a smaller successor of Hirth’s earlier 20 m. Moazagotl.
Distinctive in many respects, the Minimoa was stable, but with poor roll control by later standards. It was the first sailplane to carry water ballast, in a tank behind the cockpit. Structure: wood/ fabric wings and tail, wood fuselage

Goppingen GÖ-1 Wolf 1

The Wolf was named after Wolf Hirth, partner with Martin Schempp in the then new firm of Sportflugzeugbau Goppingen (now Schempp-Hirth). It was produced in 1935 as a rival to the Schneider Grunau Baby as a utility (rather than a high performance) sailplane. It lacks any approach control devices but has a built-in wheel, an unusual feature for the time. It was used widely for aerobatic displays, for which it could be fitted with an extra strut (making a V- strut) to permit inverted maneuvers.

It had poor spinning characteristics, and in 1938 all those flying in Germany were grounded until modifications were incorporated in the wingtip and ailerons.

Schempp-Hirth Flugzeugbau Gmbh

Martin Schempp and Wolf Hirth first met in 1928 and beginning in 1935, the team developed the Minimoa, the first high performance glider to sell more than 100 models. The production of Schempp-Hirth gliders began in the municipal building yard in Göppingen, near Stuttgart, where Martin Schempp founded the Sportflugzeugbau Göppingen (Sport Aircraft Göppingen) company in 1935.
In 1938 the company moved to Kirchheim/Teck and employed more than 300 people during the war time.
The first serial gliders were the aerobatic single seat trainer GÖ-1 ‘Wolf’ from Wolf Hirth and the renown GÖ-3 ‘Minimoa’ as well as the two seat GÖ-4 from Wolfgang Hütter. Occasionally there are single examples which are preserved and maintained as oldtimers which can still be found at airshows.
During the war, the production was forcefully expanded to build parts for, amongst other things, the ME-109, the “Giant” and for the Bachem “Natter”. Alongside the GÖ-4 there were also complete aircraft which were built, like the GÖ-8 and the 13,6m-“Habicht”.
The period after the war till 1955 was bridged with the production of plywood suitcases, leg prosthesis, furniture, weaving looms etc, yet also with fighter jet dummies (F-86) and sound studios for television stations.
The connection to the aviation industry was implemented early on with the production of the Matteson M-1 glider, the production of the powered aircraft GS-6a “Milan” and with works on engine pod and tail section of the “Trumpf” airship D-LEDA.
Licenced production such as “Emeraude” and “Smaragd”, subcontracting for “Kl-107” “, “Do-27”, “Do-28” and subsequently the production of the Standard Austria glider in several versions, ensured the employment of the about 50 employees till 1965.
In 1960s company renamed and built the Milan 656 light tourer, also French Piel Emeraude under licence. During early 1960s production of powered aircraft ceased, licence rights for Emeraude being transferred to Binder Aviatik KG.
Regaining a foothold in the world market was achieved with an own design, the SHK, by Rolf Kunz which was flown into third place in its first attempt at the 1965 World Championships in South Cerny/England.
After that the technology revolution from wood to fiberglass was completed in quick steps – at Schempp-Hirth under the directorship of Klaus Holighaus, who, with the maiden flight of his Cirrus in January 1967, was able to celebrate a successful debut.
Two years later, again in January, he already flew his first “Super Orchid”, the Nimbus-1. With this glider George Moffat won the 1970 World Championships in Marfa/Texas, USA.
With more than 700 produced examples, (of which 200 were produced by Grob), the Standard Cirrus was Schempp-Hirth’s second most successful aircraft in produced units. Further successes followed in 1972 and 1974 when Göran Ax in Yugoslavia and George Moffat in Australia became World Champions in the Open Class flying the Nimbus-2 (the production version of the Nimbus-1).
1974 also marked the maiden flight of the Janus, being the worlds first two seat glider in fiberglass construction. Constantly refined (e.g. 20 m CFK wings) it was only retired from production in 1996 after over 20 years. The last variants were the janus-Ce and janus-CT.
Also in 1974, there was the maiden flight of the single seat motorglider Nimbus-2M. Not only were the first experiences with retractable engines achieved, but also numerous world records were set, from the limited series production.
For the FAI introduced “15 m Racing Class”, Schempp-Hirth delivered the Mini-Nimbus, which came on to the market in many versions and was superseded in 1980 by the Ventus.
A new material had found its way, however, into the Kirchheimer production halls: the carbon fiber. What was included into the Nimbus-2C in a rather inconspicuous manner, proved itself to be the start of, at that time not appreciative of how large, an effective future in the production of high performance gliders. The thin wing profiles of the succeeding developments would not have been possible without the higher strength and stiffness of the carbon fiber.
The lengthening of the lifespan for fiberglass constructed gliders from 3000 to 6000 hours was for example, proven with a Nimbus-2 inner wing.
Serial introduction of carbon fiber was first included on the Nimbus-2C, Mini-Nimbus-C, Janus-C and Janus-CM. the optimal qualities of this new material were only utilized fully later on in the Ventus and Nimbus-3, in the production of the long and thin wings of these models.
Just a few months after its maiden flight, the Nimbus-3 won the 1981 World Championships in Paderborn.
Then the Ventus and Nimbus-3 won the 1983 World Championships in Hobbs/USA and subsequently the Nimbus-3 was also at the front in Rieti in 1985. Together with this, a string of national championships titles for both models and a number of world records for the Nimbus-3 were achieved.
Whilst the production of the single seat Nimbus-3 had to be discontinued after a fire in one of the production halls, this enabled the production of the Racing Class glider Ventus to be increased, allowing the increase in demand for its motorized variant Ventus-bT to be satisfied.
Constant refinement was also the key for the success of the Racing Class glider Ventus which debuted in spring 1986 as the model Ventus-c (on request with wing tip extensions for 17,6 m wingspan). Production of this model was ceased in 1994 after over 600 examples were produced (including self launchers and turbos).
January 1998 saw the delivery of the 4000th built Schempp-Hirth aircraft since the start of the company (including aircraft built under licence).
Today thousands of their gliders are flying around the world. Schempp-Hirth sailplanes include the Ventus A, an advanced 15-meter-class plane with carbon-fiber technology, thin wings, and a low-profile fuselage. The Ventus B is a 15-meter-class craft with a larger cockpit for tall pilots. The Nimbus 2C (open class) has a 20.3- meter wingspan with either carbon or carbon/fiberglass construction. The Janus B has an 18.2-meter wingspan for high-performance tandem two-place flying. The Janus C has a 20-meter span with carbon wings, seating for two, and competition-type performance. The Janus CM, with a 20-meter span, is a two-place motorglider with carbon wings and fully retractable engine. Schempp-Hirth’s newest sailplanes include the Discus, Duo Discus, Ventus and Nimbus, available in a variety of variations, including pure gliders and powered sailplanes.

Schapel SA-882 Flying Wing

The SA-882 is a flying wing which was designed and built to research the overall aerodynamics, control and flying characteristics of a tailless airplane configuration.
The Schapel Wing is powered by a turbo-charged Mazda, 2 chamber, rotary engine. The 3-bladed propeller is ground adjustable and is driven by a 40-inch long drive shaft. Propeller 2:1 speed reduction is accomplished by a helical gear speed reducer. The engine gave them some problems during the dyno testing phase, but a successful combination was finally developed.
The aircraft was built in female molds using an epoxy system, vaccumed, and cured at 240 degrees F. in an oven. The upper and lower surfaces are a foam sandwich with a three spar system out to the landing gear position and then two spars out to the tip. The wing has five ribs per side and uses a non-laminar flow airfoil of his own design with a very low pitching moment. The wing has a lot of twist between the root and tip, with about 9 degrees negative by the time you reach the tip. This was designed to achieve a zero pitching moment, which has since been confirmed through the flight testing. Max CL came out to about .85, and was driven by all the actuation mechanisms had to be enclosed.

The actual construction involved using unidirectional material, laid up at different angles as required by the results of a computer analysis. They built a male plug, a set of one piece female molds for everything and, then the PVC sandwiched skins constructed. This type of construction gave it about a 1300 lb. empty weight, with a fuel capacity of 57 gallons right at the CG. The spars were made up separately, then added to the laminated lower skins along with the ribs and then bonded all together. The upper skins, in their molds, were then bolted on-top of the low portion so a spar cap could be cast to measure the thickness between the spar and upper skin. Once the skin was constructed, the whole thing was bolted together and put in the oven for curing.

It should have had a steerable nose gear, which it did not. Low speed controllability during the initial phases of takeoff required using a lot of brakes, since the drag rudders were ineffective. This was due to them being at the MAC rather than the wingtips so the pitching moments wouldn’t be changed during flight.

A single-place monoplane, powered by a 180hp turbo Mazda rotary pusher, one was built to full scale circa 1985 and registered N882SA. The SA-882 was flight-tested in 1984 and is now preserved by the Planes of Fame Museum, Chino, Nevada.

Several things the builder said he would change if he did it again were: put the drag rudders out at the wingtips; instead of having separate elevator and ailerons he would combine the two, and; he felt it would be much simpler to put a jet engine (about 400 lbs thrust) in it versus the rotary.
