A 53-010001 wheel bump fairing test panel was subjected to a hot air blast which produced temperatures of 275 to 305F at the surface, and dynamic pressures of 15 psig. An air blast was directed to the EC 1675 and fiberglass fairing juncture, and to the aluminum-filled fairing compound and the skin juncture. Each juncture was subjected to 25 cycles of combined heating and air blast and cooled to 100F between cycles. No significant damage occurred in either of the areas. Author
