The HP-18 is a Richard Schreder-designed metal Racing Class sailplane that was offered as a kit for homebuilding during the 1970s and 1980s. [2]
The HP-18 is a flapped (15-meter) sailplane featuring a V-tail and 90-degree flaps for glidepath control. The fuselage is composed of a prefabricated composite forward fuselage and a semi-monocoque aft fuselage, and features steeply reclined seating and a side-stick controller [2] although modifications using a conventional stick have been made.
Major features:
As most homebuilts, the HP-18 has been constructed with many variations in detail. Perhaps the most significant version is the Super HP-18 developed by Canadians Ed Hollestelle and Udo Rumpf, which features a modified wing airfoil, winglets, a front-hinged canopy, conventional control stick and higher ballast capacity.
General characteristics
Performance
The Glaser-Dirks DG-300 is a Standard Class single-seat high-performance glider built from glass-reinforced plastic. The DG-300 was designed by Wilhelm Dirks and manufactured by Glaser-Dirks Flugzeugbau's Slovenian partner company Elan (company). A total of 511 of all versions were built since production started in 1983. Representative contemporary types from competing manufacturers are the Rolladen-Schneider LS4 and the Schempp-Hirth Discus.
HpH 304 is a family of sailplanes ranging from a single-seat composite 15 metre Class to a two-place 20 metre Open Class manufactured by the Czech company HpH Ltd. The sailplane was derived from a glider made by Glasflügel between 1980 and 1982 that was put back in production by HpH and who have modified it substantially and developed new models since.
The RS-15 is a Richard Schreder-designed metal Racing Class sailplane that was offered as a kit for homebuilding during the 1970s and 1980s.
Richard E. Schreder was an American naval aviator and sailplane developer, responsible for design and development of the HP/RS-series kit sailplanes marketed from 1962 until about 1982. Schreder also founded and ran Airmate, a successful drafting supplies company.
The Briegleb BG-12 is a single-seat sailplane of wooden construction developed in the United States in the 1950s. It was marketed for homebuilding in plans or kit form, with over 350 sets of plans selling by 1978. The BG-12 is a conventional sailplane design, with a high cantilever wing and a conventional empennage. Later models featured a highly revised fuselage, a swept-forward tail fin, and an all flying tailplane with balance tabs.
The HP-14 is a Richard Schreder-designed all-metal glider aircraft that was offered as a kit for homebuilding during the 1960s and 1970s. It was originally developed by retrofitting improved wings to the fuselage and tail of the HP-13, and first flew in 1966. Schreder won the 1966 US national soaring championship in the prototype HP-14.
The Rutan Model 77 Solitaire is an American, single seat, canard, mid-wing motor glider that was developed by Burt Rutan in response to the 1982 Sailplane Homebuilders Association Design Contest for a homebuilt glider. It first flew in 1982. The Solitaire was declared the winner of the contest and its unusual layout attracted a great deal of attention. For a time in the 1980s the aircraft was available as plans and as a kit.
The Schreder Airmate HP-9 is an American high wing, single seat glider that was designed by Richard Schreder and intended to be flown by the designer in the 1960 World Gliding Championships.
The Schreder Airmate HP-10 is an American, high wing, single seat, FAI Standard Class glider that was designed by Richard Schreder. Airmate was the name of Schreder's design company.
The Schreder Airmate HP-11 is an American mid-wing, V-tailed, single seat glider designed by Richard Schreder. Airmate was the name of Schreder's design company.
The Schreder HP-16 is an American mid-wing, single seat, V tailed, FAI Standard Class glider that was designed by Richard Schreder.
The Schreder HP-17 was an American mid-wing, V tailed, single seat, experimental glider designed by Richard Schreder to test a new airfoil section.
The Schreder HP-19 is an American, high-wing, T-tail, single seat glider designed by Richard Schreder.
The Schreder HP-20 is an American, high-wing, T-tail, single seat glider designed by Richard Schreder.
The Schreder HP-21 was an American high-wing, variable geometry, V tailed, single seat motor glider project that was designed by Richard Schreder. None was ever completed or flown.
The Schreder HP-22 was an American mid-wing, amphibious flying boat, cruciform tailed, two seat motor glider project that was designed by Richard Schreder. None were ever completed or flown.
The Bowlus BZ-1 is an American single seat FAI 15 Meter Class, V-tailed glider that was designed and built by Michael Bowlus.
The Chase-Sisley C100-S is an American mid-wing, single seat FAI Open Class glider that was designed in the 1960s by Dr. Robert Chase.
