"What Is It?" Contest Previous Quiz Answer:
Northrop
Model: Gamma 2F
Type: A-17A
Aircraft: 35-122
Modified by Douglas for the NACA. This machine was used to test the maximum wing chord that could maintain
laminar flow, the results of which were employed in the C-74. The propellers are to simulate propwash. The wing
form achieved a fair amount of success (30% top- 60% bottom), but as in all similar designs before the "clean"
wing form was not operationally viable.
