Gentlemen:

  This Command wishes to thank you for your letter of 17 January 1947 and inclosure thereto in which you described three airplane designs, a Jet Fighter, an Attack Airplane, and a High Speed Utility Twin Jet Airplane. It was indicated in your letter that a review of these preliminary design studies was desired.

  Your designs have been carefully studied insofar as possible consistent with the data furnished. It appears that the designs are all based on the Burnelli "lifting fuselage" which has been previously submitted and evaluated by this Command. It further appears that the new features of this design consist principally of adapting jet type engines to the lifting type fuselage. While many advantages may be claimed for this combination of lifting fuselage with jet engines, the principle benefits claimed with lifting type fuselage design have been achieved on AAF aircraft by use of stream- lined bodies upon which low drag rather than high lift has been emphasized. It is to be further pointed out that the lifting type fuselage has a relatively low critical speed which definitely limits the future development of this type airplane. Such limitation is not desirable in view o the AAF requirements for extremely high speed aircraft.

  In view of recent severe cuts in AAF appropriations and after due consideration, it have been determined the sub- mitted designs do not establish sufficient basis for re- commending contractual action to further exploit your designs.

  Your continued interest in AAF matters is appreciated.

 

Very Truly Yours

 

S.R. BRENTNALL,
Colonel, Air Corps,
Chief, Engineering Operations
Engineering Division.
