studied spiked blunt body drag in a hypersonic shock tunnel
and showed that drag reduction significantly decreased as attack angle increased.
Sergio Aguero forced to step in as furious Lionel Messi involved in shock tunnel
But, the frequency of vibrations in a metallic diaphragm-explosion-driven test facility, such as a shock tunnel
, is generally very high and a measurement technique deployed can work successfully if the sensors have a moderate operating frequency In other words, a mismatch must exist between the natural frequency of the model and the operating frequency of the sensors to carry out measurements in hypersonic impulse facilities .
A football star who fractured an opponents jaw in a shock tunnel
bust-up has escaped jail.
Other researchers also have noticed that coaxial thermocouples are more robust and durable as compared to thin-film sensors when it comes to the application of measuring the heat flux in the harsh environment [9, 10] Moreover, thermal sensors are routinely used in shock tunnels
, expansion tubes, free-piston shock tunnel
, and gun tunnels .
The simplest Reflected Hypersonic Shock Tunnel
is a shock tube equipped with a convergent-divergent nozzle to produce high Mach number and high enthalpy flows in the test section close to those encountered during the atmospheric flight of the 14-X B at hypervelocity.
. All tests were conducted in the reflected shock tunnel
of Nagoya University.
