H. Po Bruns - 2 - January 13, 1970

transmission was installed Saturday night for endurance testing of brakes Sunday. The
driver failed to show up Sunday so the test was scrubbed and the vehicle returned to
Huntsville.

Rework of the test vehicle began during the holidays in preparation for Talladega
tests 5 January 1970o A new engine (D-4 heads) was installed, suspension system
changed, rear brake cooling ducts removed, and general changes made for oval track
testing.

a. Test Support

The Daytona test vehicle was instrumented for measuring the
following parameters:

Engine Speed
Front Wheel Speed
Manifold Vacuum
Acceleration Longitudinal
Acceleration Lateral
Acceleration Vertical
Steering Wheel Position
Yaw or Slip Angle
Left Front Wheel Position
Right Front Wheel Position
Left Rear Wheel Position
Right Rear Wheel Position
Engine Oil Pressure
Brake Line Pressure
Brake Lining Temperatures (4 Wheels)
Engine Water Temperature

The system was checked out upon arrival at Riverside and problems
arose with the Lockheed tape recorder which would not lock in speed synchronization. A
Lockheed serviceman made temporary repairs to the recorder Sunday prior to tests and
ordered replacement parts from the factory in New Jersey. The unit functioned mar­
ginally throughout early testing and Thursday while the transmission was being installed
the recorder was taken to the service representative in San Francisco for replacement
of the defective part (a tachometer speed sensor) . No further problems arose.

Test data was reduced and analyzed by engineering. Records were
made of performance braking and handling for base line runs as well as comparative
system performance for brakes, transmissions, engines, exhaust systems, drivers,
etc.
