According to China Aviation Industry Group news, recently, the group pneumatic courtyard1 m hypersonic aerodynamic wind tunnel & LDQUO; FL-64” The main Mach number flow field calibration was successfully completed, flow field uniformity index and force measurement accuracy index of standard mold met relevant requirements, and the first-stage debugging was successfully completed, formally forming the model test capability.

The FL-64 wind tunnel took only two years to build and set a speed record for a hypersonic wind tunnel of its type.

Wind tunnel is the basic aerodynamics test facility for the development of aerospace aircraft, aircraft, missile, spacecraft and rocket design are inseparable from it.

The aviation Industry Pneumatic Institute is the earliest aerodynamic research institution in China, and the first high speed wind tunnel FL-1 was born here in 1959.At present, low-speed wind tunnel groups represented by FL-8, FL-9, FL-10 and FL-51 have been built, and high-speed wind tunnel groups represented by FL-2, FL-3, FL-60 and FL-62 have been built.


At the end of 2013, the first hypersonic wind tunnel of the Aviation Industry Pneumatic Institute was approved for constructionCombined pulsed high enthalpy wind tunnel with 0.3-0.5m diameter & LDQUO; FL-63”, operating Mach numbers 3.0-10.0, aero-thermal prediction for low and medium Mach numbers and related basic problems research, has been built and put into use.



1 m hypersonic aerodynamic wind tunnel & LDQUO; FL-64” The construction will be officially started at the end of 2019, and the wind-tunnel main body construction and main Mach number commissioning will be completed in September 2021.

Fl-64 wind tunnel is a 1m scale hypersonic aerodynamic wind tunnel newly constructed in China. It has a design Mach number range of 4.0-8.0, a maximum simulated total temperature of 900K, and a maximum simulated altitude of 48km. It has two operating modes of blowing and suction, and an effective operating time of no less than 30 seconds.

The FL-64 wind tunnel can meet the test requirements of hypersonic vehicles such as conventional force/pressure measurement, inlet, dynamic simulation, weapon separation and delivery, aerodynamic heat, and flow display.

The wind tunnel hasSimulation ability to reproduce Mach number 4.0 total enthalpy, take advantage of high temperature clean air heating capacity, innovation in development of the Mach number 4.0 the combination of the dynamic performance test, thermal coupling within the aircraft flight integration force test, pneumatic heat load test, the heat dynamic characteristics of elastic coupling of several test test technology, can be developed for M4.0 level of hypersonic flight vehicle to provide reliable, comprehensive data support and validation.

Fl-64 wind tunnel is a large-scale ground wind tunnel test facility for hypersonic vehicle aerodynamic/thermal and related problems research and technical verification, based on the service of the national space and space strategy, to solve the model aerodynamic problems urgently needed.

When it's up and running,For China's hypersonic weapons and equipment development and support to add weightIt plays an irreplaceable role in hypersonic aerodynamic basic technology research, aerodynamic layout selection and verification and key engineering problems.
