Figure 11, Flow-distribution device incorporating an egg-crate' type of flow straightener. Figure 12. Flow splitter in propellant feed system of LEM descent engine. Figure 12. Flow splitter in propellant feed system of LEM descent engine. One problem associated with flow straighteners or splitters, or any other structure that rigidly spans the diameter of a duct, is structural loading by differential thermal expansion or contraction. In a duct, the vane usually heats or cools during thermal...

Filter Element

Mechanical filter elements remove contamination from a fluid system by physically trapping the particles as they pass through the filter material. The filter element can be either a surface or a depth type, A surface filter performs Its function by trapping particulate contamination on the upstream side of the filter surface at the inlets of the filter material capillaries. A depth filter performs its function by trapping particulate contamination within the intricate capillary system of the...

b End construction for smal 1-diameter braided metal hose temperatures above 400 F c End construction for braided metal hose 3-tn. 10 and over temperatures from cryogenic to 1 00 F Figure 44, Braided-hose end construction for specific applications. A common problem, especially with small ii-in. diam. hoses, is the overangulation and subsequent braid bulging at the ends of the hose. A solution widely used with commercial clastomeric hoses is the placing of external coil springs over the braid...

The cross-sectional area of the manifold decreases as it wraps around the chamber, so that a constant gas velocity is maintained as the gases are bled off through openings in the thrust-chamber wall. The junction of the manifold and thrust-chamber...

Test Instrumentation

Typical parameters measured on lines, bellows, and flexible hoses during development and qualification testing include static and total pressure, temperature, flowrate, strain, and vibration response. Pressure and temperature measurements are obtained with standard low-frequency pressure transducers and thermocouples. Orifice meters, venturi meters, and turbine flowmeters are utilized for flow rate measurements. Turbine meters must be used with caution in cryogenic service where overspeeding...
