The Schreder HP-16 is an American mid-wing, single seat, V tailed, FAI Standard Class glider that was designed by Richard Schreder.[1][2]

Design and development

After the failure of the HP-15 to perform well in the 1969 US Nationals Schreder started the HP-16 with a new design philosophy. Avoiding the extremely high aspect ratio that the 15 had, he opted for a more modest 21.5:1 aspect ratio and larger wing area to improve performance in weak conditions. The HP-16's wing has 50% more wing area than the HP-15 and uses a Wortmann 67-150 airfoil.[1][2]

Like other Schreder designs the HP-16 is of all-metal construction, but with the wing skins bonded to foam ribs rather than using rivets to provide a smoother surface. The bonded construction also cut building time. The wing features the signature Schreder 90° flaps that allow steep descents and the use of small fields for landing.[1][2]

The HP-16s were all amateur-built aircraft and about 20 were completed and flown.[1][2]

Operational history

In April 2011 there were still eleven HP-16s registered with the US Federal Aviation Administration and two registered with Transport Canada.[3][4]
