The US PATENT NUMBER 4,447,024 is designated for the Williams X-Jet. Technical information and drawings are available at the United States Patent and Trademark Office. The WASP II uses a slightly modified and derated version of the WR-19-A7D which yields 600 lbs thrust from its micro turbofan engine and is designated WR19-7 ― rated at 570 lbs thrust, after minor modifications and said derating. Modifications to the WR-19-A7D included accessories (replacement of pyro starter with electric/air start) and exhaust system modifications. No internal modifications to the counter-rotating micro turbofans were performed. The first manned, untethered flight was conducted in April 1980. Ray Le Grande is one of the WASP II operators trained by Williams International to fly the X-Jet.
