Abstract

The invention discloses a long-distance liquid oxygen supply system. The system comprises a liquid oxygen container, a liquid oxygen collector as well as a filling unit, a delivery unit, an emptying unit and a pressurizing unit which are connected with the liquid oxygen container; the pressurizing unit is used for pressurizing the liquid oxygen container and comprises a pressurizing pipeline as well as a first manual pressurizing isolating valve, a throttle orifice plate group, a pressurizing solenoid valve group and a second manual pressurizing isolating valve which are sequentially arranged on the pressurizing pipeline; the delivery unit comprises a main delivery pipeline with the length larger than 30 m; and a main isolating valve, a main pipeline filter, a first turbine flowmeter, a second turbine flowmeter, an inlet filter, a main pipeline throttle orifice plate and a pneumatic valve are sequentially arranged on the main delivery pipeline in the delivery direction of liquid oxygen. The system solves the problem that existing liquid oxygen supply systems cannot meet the requirement for long-distance delivery of the liquid oxygen; and on the basis of the system, the invention discloses a corresponding precooling method which has the advantages of high precooling speed and uniform cooling.

Description

technical field [0001] The invention belongs to the field of ramjet direct connection tests, in particular to a liquid oxygen supply system and a precooling method used in ramjet high-altitude simulation tests. The long-distance liquid oxygen supply system in the present invention refers to a supply system in which the main liquid oxygen transport pipeline is longer than 30m. Background technique [0002] In the ramjet high-altitude simulation test, the liquid oxygen supply system mainly provides liquid oxygen with a certain flow rate and pressure for the air inflow heating device as the oxidant for combustion. The existing liquid oxygen supply system can only supply liquid oxygen over a short distance (generally 10-20 meters), which cannot meet the high-altitude simulation test requirements of new ramjet engines. [0003] Before conducting the high-altitude simulated incoming flow test, the liquid oxygen pipeline of the liquid oxygen supply system needs to be pre-cooled to...
