Subject field(s)
  • Mechanical Components
CONT

Piston accumulators consist of a cylindrical body, sealed by a gas cap and charging valve at the gas end, and a hydraulic cap at the hydraulic end. A lightweight piston separates the gas side of the accumulator from the hydraulic side. This design offers high efficiency and flexibility in most applications due to a very wide range of sizes.

CONT

The accumulator is intended for heating fuel components in the rocket and space engines and can be used in space engineering, aircraft and other branches of industry. The task of increasing gas heating efficiency, reducing mass of the construction, diminution of dimensions and lowering thermal and hydraulic losses of heated gas is solved by making a heat accumulating element as a mono-unit in the form of cylinder. The covers with branch pipes are recessed in the ends of the mono-unit. The covers are butt joined to mono-unit on conical surfaces through pressurizing end seals at forming the collectors for gas feed and discharge. Plate electric heater and channels or annular slot for flowing gas are located along the longitudinal axis. The axis of channels or annular slot location divides the mass of heat accumulating element into two equal parts. In so doing, porous insert or a set of badly stream-lined bodies is in the channels or annular slot. All units of heat accumulator are coated with gas-dense material.

... another possible way of creating permeability in hot dry rocks is «impact fracturing». This method... [may be described in its principle. ] A bore, cased except near the lower extremity, is surmounted by a hydraulic accumulator, filled with water and pressurized by means of a pump until the accumulator weight is lifted. The lifting pressure should be perhaps about 90% of the estimated hydro-fracturing pressure. A dynamic blow would then be struck upon the top of the water column by means of some device resembling a pile-driver, so that shock waves would travel to the base of the bore and be reflected up and down at attenuating intensity. Very high instantaneous pressures would be generated which would fracture the rock, and it is expected that the steepness of the pressure rise would be such as to resemble explosive action, so that the «star» formation... would be produced.
