Hi All!
I got this very good book.
I want to say a few comments in the book are not written:
1) USN has announced a competition to design high-speed fighter escort with long-range flight. McDonnell, do in his time first place in competition at the USN jet interceptor, is involved in the new competition.
This information from: Aviation Week,1949, Vol.50, No.4, 24/I, page ?.
This competition is a OS-112.
Nothing to say on the participation of McDonnell in this competition.
2) " There was only one award for the interceptor competition and it is not known for certain who the other competitors had been, although Bell, Boeing, and possibly Lockheed are thought to have participated. A paper by Bell Aircraft personnel in the time period was published in the Journal of the Aeronautical Sciences, comparing propeller and reaction propulsion performance. Two of the fighter examples included a "weaponized" version of the X-1 and a ram jet propelled aircraft, both fitting the requirements of the competition. Both of these examples utilized straight wings. Internal CVAC status reports confirm that Bell was a competitor but had proposed a rocket-powered design with a 45-degree delta wing. boeing was known to have also conducted design studies in the same time period also loo-
king at a ramjet and a rocket powered interceptor. Their Model 257 Interceptor fighter was powered by two wing tip ram jets and had a gross weight of 8500 lbs. It had a wing sweep of 45 degrees and used a bicycle arranged landing gear. Apparently no information survives on their rocket-powered interceptor, thought to be Model 258."
source: The Birth of the Delta Wing: Robert E. Bradley;
AAHS Journal, Winter 2003, Vol.48, No.4.
Certainly a typo: Model 257--to beat Model 457
Model 258--to beat Model 458
The book said about Model 457, but nothing on Model 458.
(This source is written in the book)
That can be said about the information?
P.S. ...still it is a very good book!!!
