Development Aerodynamics

In recent years, different systems — like the FKFS swing system — were introduced in wind tunnels to generate a transient flow field. With this development, the measurement of transient pressure data also becomes increasingly important. Pressure strips, presented by FKFS and based on the Micro-Electro-Mechanical Systems (MEMS) technology, allow the reasonable measurement of surface pressures with up to 200 Hz.

Concept

The 4Jtech 200-Hz pressure strip system consists of miniature MEMS pressure sensors installed on a flexible strip, which is both part of the mechanical structure of the device and also a Printed Circuit Board (PCB) connecting all electrical signals. Low overall dimensions are achieved with a maximum height of 1.25 mm, so that the pressure strips can be installed directly on the vehicle’s surface by using adhesive tape. This allows a higher frequency range compared to the traditional approach using long tubes, which reduce signal propagation at higher frequencies....
