Abstract

The invention relates to a low-pollution electric arc heater, which comprises a negative pole, a positive pole, an electric arc, an insulating block, a mixing chamber and a nozzle. The chamber is fixedly connected to the outlet of the positive electrode, and the nozzle is fixedly connected to the outlet of the mixing chamber. Nitrogen is passed through the negative electrode, air is passed through the connection between the negative electrode and the positive electrode, nitrogen is passed through the positive electrode, and oxygen is passed through the mixing chamber. The present invention has The advantages of reducing the copper pollution caused by the burning of the arc heater electrode and reducing the content of nitrogen oxides.

Description

Technical field[0001]The invention relates to the technical field of hypersonic aircraft test equipment, in particular to a low-pollution arc heater.Background technique[0002]The arc heater is an important ground facility for the thermal environment simulation test of hypersonic aircraft. The arc heater uses arc discharge to heat the air to form a high temperature and high speed flow field for testing. When heating the air, the nitrogen and oxygen in the air are dissociated to form nitrogen oxide compounds. The presence of nitrogen oxide compounds causes the test medium to deviate from the real air composition during simulated flight. For gas medium, strict engine combustion and thrust characteristic tests are required Bring a certain impact. Some researches believe that the presence of nitrogen oxide compounds reduces the oxygen content in the test medium, thereby reducing the heat release of the combustion reaction. In addition, the electrode of the arc heater is made of copper, a...
