the pa C D r t fiv years. In addition, all automotive trade journals and publications

will be scrutinized for pertinent articles written within the last five years.

A search will also be made in the Central Engineering library to unearth—

any elated work.

An evaluation of the information developed during this search will

then be made to insure emphasis is placed on the proper parameters during

testing. This information should also reveal the latest testing techniques and

imulation parameters (i, e. , advantages of moving ground plane over

ound board, if any; effects of spinning wheels, vibration effects, etc. ).

Second, an economic and feasibility study will < D o onducted to determine

Consideration will be given to test article cost, test complexity, tunnel

cost, tunnel availability, and scaling effects. Included in this study will C T D C

an investigation of the proper modeling parameters for engine cooling

Third, it is proposed that a survey of low sp ed wind tunnels be mad 0

to develop candidate facilities. Cost is always a significant parameter in

any program, so all available tunnels will be investigated to insure that

maximum benefits are derived from dollars expended. Availability, particu-

larly with government owned facilities, is often a critical factor. This

will be cleared early in the program. Tunnel operating parameters

(temperature, dynamic pressure, velocity, ) will be listed for each
