Subsonex JSX-1

Sonex Aircraft, LLC, Oshkosh, WI

 

The SubSonex Personal Jet concept was first unveiled at EAA AirVenture Oshkosh 2009. After successful pairing with the PBS TJ-100 engine (the same Czech-built engine that powers Carlton's Super Salto and BonusJet jet-powered gliders), the SubSonex jet aircraft prototype, JSX-1, made its first flight on August 10, 2011  at Wittman Airport in Oshkosh, Wisconsin. Piloted by Bob Carlton. The flight lasted approximately 14 minutes and focused on low-end speed, including stalls and low approaches in the landing configuration. The JSX-1 completed a successful flight test program in 2012.

Previous configuration


Due to the increased power offered by the new PBS TJ-100 engine selected for the SubSonex, it was determined that a tricycle gear configuration would be needed to increase yaw stability on the ground in the transition phase approaching takeoff speeds.

During Air Venture 2010, it was presented with the new  fixed tricycle landing gear and the PBS TJ-100 turboJet engine.
