Abstract:
The objective of this program was to determine design criteria by dynamo-meter tests of single cup-brush wheels. Paired cup-brush wheels are promising as tire-wheel-brake subsystems for landing gear on re-entry vehicles. Two-row, three-row, and four-row, 6 in. diameter brushes were tested, also four-row, eight-in. diameter brushes. Test speeds were up to 200 mihr. Loads ranged up to 2000 lb per brush. Carbon steel, stainless steel, and nickel alloy steel bristles were evaluated. Parameters were camber angle, diameter, number of rows, materials, wire diameter, knot length, load, and speed. Constructions, test results, and analysis of results appear in the report. General results were 1 the larger the diameter, the greater the load capacity 2 the greater the quantity of rows, the greater the load capacity 3 stainless is more durable than carbon steel and Rene 41 nickel alloy steel is greatly superior to either stainless or carbon steel in wear characteristics 4 at a given load, drag increases with decreasing speed or camber angle and 5 load capacity varies slightly with wire size.
