Dear Don:

In response to your request for SAB comments on the Avro
"Saucer" project, the SAB has taken the following action:

The Aircratt and Fropulsion Panels were briefed on September
28 by representatives of Hg. ARDC, at the time of the Fall meeting
of the Board in Omaba. The tentative conclusions of both panels
immediately after this briefing were to the effect that this pro-
ject warranted no more than limited support. However, to assure
thorough consideration of this project, I requested representatives
of these two ls to supplement the briefings given to them at
Omaha by a visit to A. V. Roe Canade Lid., Malton, Ontario.

With the advice of Clark Millikan and Dean Soterberg, a select

mage was chosen to conelude this study. It was composed of
an Soderberg, Chairman of the Propulsion Panel and senior menber

oe the group; Professor Ma: ; of the Aircraft wl: and Mr.

Donovan, who has been serving poth as a menber of the Aireri
and as liaison member with the Propuleaion Panel.

Pane 1.

The attached report of thia group is forward
representing the results of the SAB’s completed, study.

y approval,

Sincerely,

Scieatifie Advisory Board

cally appraised, it is now locked upon as en alternative form of

equal promise.

It ig evident thet the invention involves a whole array of for-

midable problems of research and development. Even in the smailest

versions the outer diameter of the redial flow turbine is about

twenty feet. The entire rotor must be supported on air bearings in

the radial as well as the axial direction, and it is evident…
