Air Data Boom
The air data system combines a Kiel-type pitot static port, vanes for angle-of-attack and angle-of-sideslip measurement and a battery-powered air data computer in a lightweight probe. It is designed for quick and easy temporary attachment to any airframe in fast-paced flight test applications. It provides the following parameters:
- Pitot Pressure
- Static Pressure
Test flight data can be viewed in real-time on a PC resp. tablet or downloaded and analyzed post-flight. Due to the non intrusive nature of its wifi modem no harnessing of the test aircraft is required.
The wifi system has a range of approximately 150 m. Data analysis can be performed by a flight test engineer on-board or in a chase aircraft.
GPS / INS / Data Acquisition Unit – BoxDAQ
The BoxDAQ combines a commercial-grade GPS/INS, a wifi receiver and a custom datalogger into a rugged box. This integrated solution provides the following parameters:
- Roll rate/pitch rate/yaw rate
- 3-axis velocity (North-East-Down)
- 3-axis acceleration (XYZ)
In addition to the parameters above, the BoxDAQ receives data from wifi-compatible sensors within range. This feature enables EURO FLIGHT TEST to log air data from the air data boom and control surface positions alongside INS data in a single data acquisition unit. Thus the BoxDAQ represents the core of a full instrumentation solution for common flight test tasks.
The Inertial BoxDAQ integrates an advanced GPS/INS with Kalman filtering to combine data from a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer and a GPS receiver. A low-pass filter is applied to the 800 Hz raw data to minimize the effects of airframe vibrations. Finally, the data is downsampled to a clean 50 Hz signal.
