From a technical perspective Service in the Swedish Airforce 1943-1952 |
Fighter comparison, 1000-1150hp Fighter comparison, mid to late 1943 |
I have prepared this web page in order to shed some light on a unique, little well known and obscure fighter aircraft developed in Sweden as a stop-gap measure during WW II. The J22 would become the "fastest aircraft in the world in reference to engine power", and I have tried to show all the unique features, details and performance in this web page. This web page is dedicated to all the people who flew this aircraft, the people who helped me gather information, the Engineers who designed and developed the J22, the people who assembled and manufactured the J22 and finally the people who are eager to preserve the few remaining aircraft. It has been difficult to do the research, as very little in-depth technical information is available. The best source has been Bo Widfeldt's book: "F.F.V.S J22", which covers a lot of the total history and development. The information that I have not yet been able to find are the flight test reports, center of gravity locations, wind tunnel test data and actual performance graphs. Any help in this area would be greatly appreciated. My interest has been the technical and engineering details since this is what I do for a living as an aerospace engineer. I am also an instrument rated private pilot. I hope this information will show what unique aircraft it was and also how it compared with other aircraft of that era.
