In the spn Grob has incorporated much of its experience with high-performance sailplanes to produce an aircraft with exceptionally smooth surfaces, free from drag-inducing blemishes.
Over 2,000 FJ44 series engines are now in use and have demonstrated a high reliability rate, with hot and cold section inspection intervals set at 2,000 and 4,000 hours respectively.
For flight test measurements a long pitot static probe was fitted to the aircraft. This will be removed for production aircraft. The first prototype, seen here, is being used for performance and flight dynamics testing.
Flight trials were carried out to demonstrate the spn’s ability to operate from grass airfields.
Grob has engaged the Porsche Design Studio to carry out the detailed work on the cabin seating and layout, bringing the clean lines of Porsche cars to the spn’s interior with state-of-the-art ergonomics, luxury materials and a fresh, contemporary feel to the cabin.
Although the spn is approved for single pilot operation, the cockpit installation is configured for an optional second pilot and will allow either to fly the aircraft. The primary flight displays ahead of the control yokes and centrally-located multi-function displays of the Primus Apex all-glass cockpit are clearly visible in this photograph.
