产品描述

A hypersonic wind tunnel means that the Mach number in the experimental section ranges from about 5 to 14, and the airflow temperature is high enough to prevent liquefaction in the experimental section when the airflow isentropically expanded to the above Mach number, but there is no wind high enough to produce real gas effects. Hole.

There are two types of hypersonic wind tunnels: continuous and intermittent. Air heaters are installed in the hypersonic wind tunnel. The total temperature of the airflow in the hypersonic wind tunnel is high, which will overheat the throat of the nozzle, and cooling measures must be taken; The shape of the curved wall of the hypersonic nozzle changes drastically, the throat is narrow, and it is volatile at high temperature, so an axisymmetric nozzle is usually used. Most hypersonic wind tunnels are intermittent, and the blow-suction type is more common. If the heater is a resistance heater, the total temperature of the airflow can be heated to about 1500K. This temperature can prevent the gas flow from liquefying in the range of Mach number below about 14, but can only simulate the enthalpy of Mach number below 6, and cannot simulate the enthalpy of the higher Mach number in the hypersonic range.

Hypersonic wind tunnels are mainly used for model experiments of missiles, satellites, and space shuttles. Experimental items usually include aerodynamic force, pressure, heat transfer measurement and flow field display, as well as dynamic stability, low melting point model ablation, mass ejection and particle erosion measurement. Hypersonic wind tunnels mainly include conventional hypersonic wind tunnels, low-density wind tunnels, shock wind tunnels, and thermal shock wind tunnels.

The JF12 hypersonic wind tunnel is known internationally as "Hyper Dragon". It is the world's largest shock wind tunnel and the world's first hypersonic wind tunnel that can reproduce flight conditions. It has achieved my country's independent research on advanced air A precedent for kinetic test rigs. Reproducible wind tunnel theory and technology have solved the world problems that have plagued hypersonic ground tests for 60 years, realized the leap from flow "simulation" to "recurrence" of wind tunnel test status, and led the development of international advanced wind tunnel experimental technology. .

We provide hypersonic wind tunnel test services.
