| Abstract | This report outlines the current status of the CF-105 project as determined during a period of liaison with Avro Aircraft Ltd. in May and June, 1955.
Attention is called particularly to aircraft performance, stability and control characteristics upon which the success of the project is critically dependent.
It is noted that the weight of the aircraft has increased substantially since the publication of the most recent brochure. At the same time estimates of thrust and drag are in process of revision. It is believed that in consequence of these changes the performance to be expected is now below that specified. To definitely establish the present relationship between expected and specified performance a new and thorough analysis supported by an independent check is urgently required.
As soon as reliable figures are available it is recommended that the extent of expected performance deficiencies be communicated to the R.C.A.F.
It is anticipated that means of significantly reducing all component weights will be required. It is therefore suggested that early consideration be given by the R.C.A.F. to an extreme program of armament and equipment weight reduction. In the present concept of the CF-105, a system for artificially augmenting the stability is essential to the safety of the aircraft at some combinations of Mach number, altitude and load factor. It is proposed to achieve adequate reliability by providing also an emergency augmentation system.
The task undertaken is considerably more complex than that of merely supplementing the natural damping of the aircraft, a course of action which has been followed on many contemporary types in countering the loss of damping resulting from increasing altitude.
At least as a precaution against unexpected obstacles in the development of the proposed system, a further effort by means of wind tunnel and simulator studies specifically aimed at improving the natural stability and control characteristics of the aircraft appears to be warranted at this time and is recommended.
Some less extensive problems of design and operation requiring investigation and offering scope for further contributions to the project are also noted in this report. |
