96 CHAPTER 5 Controversy, 1975–1991<br />

AIRCRAFT<br />

During the period 1975–1991, NASA research aircraft appeared with a variety of<br />

insignia and, for the first time, an increased number of logos that identified partners<br />

and sponsors for research projects. Many of the paint schemes were chosen to<br />

enhance the visibility of the vehicle as well as airflow over and around its surfaces.<br />

FIGURE 5-8.<br />

The NASA F-18 High Alpha Research Vehicle (HARV)<br />

had a special black finish to enhance visual analysis of<br />

flow characteristics over the airplane at high angles of<br />

attack. The NASA logotype insignia and the aircraft’s<br />

NASA identification number were therefore painted in a<br />

nonstandard white color. (NASA EC92-10231-2)<br />

FIGURE 5-9.<br />

The NASA logotype insignia was displayed on the vertical<br />

tail of the X-29 research aircraft in 1990. The vehicle<br />

also displayed the names of NASA’s partners including<br />

Grumman, the Defense Advanced Research Projects<br />

Agency (DARPA), and the U.S. Air Force.<br />
