摘要： A system for measuring a multiplicity of pressures as those experienced by a model in a wind tunnel is depicted. The system includes individual sensor devices which are connected to an Acquisition and Compensation electronics module. The individual sensor or transducer devices are semiconductor piezoresistive devices and are connected to the Acquisition and Compensation electronics module by means of a cable in a first embodiment. In an alternate embodiment the system uses connectors which connect each of the individual sensor devices to the Acquisition and Compensation electronics module via a mating connector located therein. The connectors may also include a memory which stores compensation coefficients associated with each of the various sensor devices. In this manner as described, the transducers which are small devices are connected via electrical lines or cables to the central Acquisition and Compensation electronics modules. This module houses electronics which digitally converts the data from the sensors and then compensates the data for temperature effects. The advantage of the system is that each individual sensor does not have any compensation and it can be made very small to operate at very high temperatures without any loss of accuracy. Thus, a large number of sensors can be utilized in a very small volume, even under extreme environmental conditions. It is noted that the Acquisition and Compensation electronics module can be located remotely in a safe environment outside of the wind tunnel and therefore respond extremely accurately to the pressure and temperatures subjected by the model in the wind tunnel.

摘要： The invention relates to closed-circuit tunnels used for aerodynamic researches, sportsmen-parachutists training and other purposes. The inventive closed-circuit tunnel comprises a confuser, a working area, a diffuser, one or several return channels, a blower unit and turning bends having different flow deflection angle, wherein the bend having the smaller flow deflection angle is placed in a high-speed flow cross-section, whereas the bend having the greater flow deflection angle is arranged in a low flow speed cross-section. In a preferred embodiment, the tunnel comprises a first turning bend containing one turning gut for turning the airflow at 60 degrees, a second turning bend containing two turning guts for turning the airflow at 120 degrees, and a third turning bend containing three turning guts for turning the airflow at 180 degrees. The invention makes it possible to reduce air pressure losses, the drive power and a specific amount of metal per structure.

摘要： The development of a nearly-omni-directional pressure probe for three-velocity-component and pressure measurements is described, with particular focus on the techniques and technology employed in probe construction, calibration, electronic interfacing and frequency-response study. The device eliminates the velocity directionality limitations of current multi-hole probes and makes a valuable, rugged tool for use in complex 3-D flow mapping and aerodynamic design and evaluation, in basic research as well as industrial development settings. The probe performance is demonstrated in a flowfield with flow reversal downstream of a backward-facing step. The probe provides low-frequency response capabilities. The probe's main element is a multi-pressure port spherical head, which may include eighteen ports. Fiber optic interferometry techniques may be incorporated to significantly increase frequency response.
