Forces

DNW regularly performs force measurements for customers that need to predict aerodynamic behavior, often dictated by the objective of reducing fuel consumption. In the aviation industry, force measurements are also used for:

Pressures

Pressure measurements play an important role in the development of aircraft, both civil and military. For example, pressure measurements can provide valuable information on the pressure distribution on either the entire fuselage or locally on a particular section of a wing. Measurements are performed at varying speeds in order to obtain a complete set of information for different circumstances.

Aeroacoustics

Environment perceived measured noise 
Noise pollution has become an item of frequent and sometimes intense political, social and economic debate, in particular in densely populated areas around airports. Aircraft noise is created by propulsion units as well as by airframe components such as undercarriages, slats and flaps. 

Flow field measurements

Intrusive measurements ─ instruments are located in the air flow and affect the flow;
Non-intrusive measurements ─ instruments are located outside the air flow and do not affect the flow.
Some projects make use of one of these two measurement types, whereas other projects require both techniques. For instance, measurements of wake vortex often consist of an initial scan with a probe (intrusive) to obtain a general impression, followed by Particle Image Velocimetry (non-intrusive) for more precise and detailed measurements.
