    In , something wholly unexpected happened at what was then the NASA Lewis (now Glenn) Research Center—a “new” aircraft icing program was started. The story goes something like this: Milt Beheim, chief of the Wind Tunnel and Flight Division, was put in charge of the nearly defunct Icing Research Tunnel (IRT). The Online Books Page.

    Technical Short Courses. A Technical Short Course is a discussion or lecture on a thermal, aerothermal, or fluids topic with a duration of one to three hours. Technical material should be applicable to NASA/aerospace missions. A technical panel of experts with group discussion can also be proposed. According to studies, the icing problem on an airfoil reduces lift by 30% while increasing drag by 40% or even more (Bragg et al., , Czernkovich, ). In particular, the changed stall characteristics impose a serious safety threat. That is the reason why icing research started soon after the invention of aircrafts in the early 20th by:

    III. EXPERIMENTAL STUDIES A. The main diffuser in the model water tunnel was made in three sec­ tions. The upstream section was an aluminum oasting bored to provide a tran­ sition between the rical test section and the conioal diffuser. The two downstream sections of the diffuser were fabricated from J/n. thick.   The bell mouth starts very large so the air is slow, and guides the air to the shape of the test section as the bell mouth narrows and the air speed increases. Tada, much smoother air flow. In addition to being a guide, it is also a nozzle, which research has found kills turbulence (any extra whirly twirly in the flow).Author: Ben Washington.

Flow quality in the NASA Lewis Research Center Icing Research Tunnel (IRT). These studies mapped the flow qual­ ity in the test section and through the tunnel loop.

The goal of • Since these flow quality studies were completed, the facility drive fan was modified such that the maximum empty test section speed is about mph.

Brook Park, Ohio Summary As part of an ongoing eftort to improve the aerodynamic flow characteristics of the Icing Research Tunnel (IRT), a modular scale model of the facility was fabricated.

NASA’s icing research involves the development of tools and methods for evaluating and simulating the growth of ice on current and future aircraft surfaces or inside the engines and the effects that ice may have on the behavior of aircraft in flight.

The tests were conducted in the Lewis Research Center Second Zero-Gravity Facility. The photographic results indicated that a sudden decrease in gravity level from 1 to 0 effected an immediate reduction in the length of the flame.The blockage indicates how much area was available for radial flow.

At the largest blockage (~=), the separation region blocked 38 ~o of the passage area. Flow visualization in a laboratory vaned diffuser: R. B. Brownell et al.
