ABSTRACT
This paper presents an open system architecture with wireless network centric telemetry and data acquisition over UDP/IP. This networked solution was designed and developed for iron bird and helicopter rotor applications which present a significant challenge for data acquisition and telemetry. Traditionally slip rings were used for data transfer however these result in issues with low bandwidth, electrical noise, installation complexity, and high maintenance costs. This paper describes a networked system using standardized technologies and protocols that was used for data acquisition and recording of parameters such as vibration, strain, and video on DAQ installed on the rotating part. The acquired data was transmitted in real-time via the network-centric wireless telemetry link which was synchronized with a ground-based DAQ used for real time processing of the rotor data.

INTRODUCTION
The wireless network centric data acquisition and telemetry solution described in this paper was designed and developed for iron bird and helicopter rotor application in order to collect and record parameters coming from rotating and static part sensors with GPS data time stamp.
This system comprises three subsystems; a static DAQ sub-system, a mobile DAQ sub- system and the wireless network-centric telemetry interface. The static DAQ sub-system monitors and records static parameters such as the engine, transmission etc. The mobile DAQ sub-system can be used either as a standalone device or integrated with the static sub-system.
As a standalone device, it supports a battery and solid state recorder. As an integrated sub- system it can interface with the static sub-system via wireless network centric telemetry in order to measure and transmit parameters from the rotating components such as the hub, swash plate and blades. This sub-system is reconfigurable and extendible to support additional channel inputs, or additional data types. In fact, since the solution is realized entirely using

The IADS software from Symvionics, shown in Figure 7, was used for monitoring and analysis of data in real-time. This software afforded significant time-saving and effort during the test. The test bench can be also stopped automatically in a real time using this software in case of any threshold and overload situation of sensors defined in the test configuration.
CONCLUSION
This paper presented the design, development and real application of a UDP based wireless network centric data acquisition system for rotary application. This solution was been successfully deployed many times during the test campaign. Not only has this been successful in terms of the reliability, real-timeliness and fidelity of the acquired data but also it has demonstrated the significant advantages of open standards based architectures in terms of installation, flexibility, cost-saving and maintenance.
