HIGH PERFORMANCE SINGLE SEATER
The all-new HPH 304S is a high-performance single-seated, flapped racing class sailplane. It is offered in a convertible wing configuration with long and short wingtip extensions allowing both 15- and 18-meter wingspans.
Not simply a face lift of an existing technology, but the very latest in a long study of what was, until now, the “State-of-the-Art”. The new HPH 304S prototype was flown on November 23rd 2006. Test pilot Ludek Kluger was surprised with the excellent characteristic of the new glider. He reported excellent flying quality from the first moment. Testing and development continued intensively. Today, we have a technically mature product that fits any pilot need.
AERODYNAMICS WITH A WIZ
The airfoil, only 13.2% thick, was designed mainly in order to reduce the influence of insect contamination on the flight performance. Towards the wing root the thickness increases to 16.4%, with special care to the wing root transition. The wing ends with an elliptically-formed leading edge and 3D curved wingtips are specially shaped to minimize the induced drag. Three-part flaperons through the whole wing span are set in the wing trailing edge. This provides the pilot with good handling and improved flight performance.
