Schreder HP-18 - Design and Development

Design and Development

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 although modifications using a conventional stick have been made.

Major features:

  • Very low cockpit with reclining seating position
  • Sidestick (changed to conventional stick by some homebuilders)
  • Two-piece canopy (changed to single piece forward opening by some homebuilders)
  • V-tail that folds upwards for easy storage
  • Wing structure composed of spars with caps pre-machined from solid aluminium plate and aluminium wing skins bonded to closely spaced foam ribs
  • Fiberglass fuselage pod, wing tip skids and tail fairings
  • Aluminium tail cone
  • Winglets added by some homebuilders
  • Water ballast carried inside the hollow aluminium wing spars
  • Typical Schreder trailing edge flaps/airbrakes partially interconnected with the ailerons

Famous quotes containing the words design and/or development:

    “Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
    —François, Duc De La Rochefoucauld (1613–1680)

    “I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
    —Benjamin Harrison (1833–1901)
