Schreder Airmate HP-9 explained

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.^{[1] [2]}

Airmate was the name of Schreder's design company.

Design and development

The HP-9, the HP indicating high performance, was Schreder's FAI Standard Class follow-on design to the FAI Open Class HP-8 and was built to compete in the 1960 Worlds in the newly established Standard Class, but was not completed in time. The HP-9 was sold unfinished to Bob Litle, Jr who had Javelin Aircraft complete the glider.

The HP-9 is constructed entirely of aluminium and has an all-flying stabilator tail. The aircraft also features dive brakes and a retractable monowheel undercarriage. The wing has Fowler flaps which increase the wing area from 127.4to and lower the minimum sink speed to 2.11 feet per second (0.64 m/s) at 470NaN0 from 2.26 ft/s (0.69 m/s) at 600NaN0.

Only one HP-9 was built.

Operational history

The sole HP-9 was still in existence in April 2011 and was listed by the Federal Aviation Administration as having been sold to the Centre County, Pennsylvania Visitor Bureau.^[3]
