2.4 Connecting the Calibration Fixture to the FTK100

This section describes how to connect the calibration fixture to the FTK100 control module.

The FTK100 supports calibration fixtures designed to test pressures on standard pitot-static probes and five-hole probes. A calibration fixture designed to test the five-hole probe integrated into the ARIM320 is shown in Figure 4. For testing the more common pitot-static probes, tubing is only required to be connected between the pitot tubing connector on the forward face of the calibration fixture, and the static tubing connector furthest aft on the side of the calibration fixture. If a five-hole probe is being tested, as shown in Figure 4, tubing must also be connected to the angleof-attack (alpha) connectors in the vertical plane and sideslip connectors in the horizontal plane. Please note that the calibration five-hole probe calibration fixtures are typically designed so that the static connector is on the same side as the Alpha+ connector. This allows the user to orient the calibration fixture correctly when installing it on the probe.

Both the FTK100 control module and Aventech Research Inc. calibration fixtures utilize 1/8” OD quick connect / disconnect fittings to interface to the interconnecting pressure tubing. To install the tubing simply insert it as far as possible into the fitting and it will lock in place. To disconnect, push down on the orange collar on the fitting and pull the tubing out.

Six lengths of 1/8” OD tubing will have been provided with your field test kit which

should be installed between the pressure connections show on the calibration fixture in Figure 4 and the labeled input ports on the FTK100 shown in Figure 2.

2.5 Installing the Calibration Fixture

For pitot-static probes, orientation of the calibration fixture is not important however, for five-hole probes it is critical. As described in Section 2.5, the static pressure fitting is typically located on the same side as the alpha+ pressure fitting.

Install the calibration fitting onto the measurement boom by sliding it over the boom while insuring the static pressure fitting is pointing straight up. This will insure that the remaining pressure fittings are oriented correctly relative to the pressure ports on the measurement boom. Slide the fixture as far as it will go onto the boom and then apply a small amount of longitudinal force to the fixture to compress the Orings against the nose of the boom and seal off the pressure ports to the calibration fixture. While applying this force, rotate the collar located at the rear of the calibration fixture clockwise, when looking at the front of the fixture, gently to lock the fixture onto the probe boom.

3.1.1 IBIT

The FTK100 will send an IBIT request to the DUT and the 32-bit status word sent in reply from the DUT will be displayed in hexadecimal format. To assist interpretation, the output includes text descriptions of each non-zero bit occurring in the status word, each representing a particular error condition.

3.1.2 CBIT

CBIT data is continuously generated by the DUT under normal operation. The FTK100 sends a request at 1Hz to continuously receive and monitor the latest CBIT values being generated by the system. Two different CBIT values will be output along with text-based descriptions of all non-zero bits denoting various error conditions.

3.1.3 Pressure Test

This feature will perform a pressure test of all five pressure ports on the tip of the air-data probe and the ring of static-pressure ports around its circumference. This test can be performed only if the appropriate probe adapter is firmly secured to the DUT and is connected to the FTK using the supplied tubing.

Immediately after the Pressure Test is selected, the internal pump will begin to pressurize the system to approximately 3000Pa. If any leaks are present, as would occur if the probe adapter is not properly in place, the pump will continue to run until a timeout error is generated if the target pressure is not reached within 6 seconds. If the no leaks occur, the pump will bring the system up to test pressure in approximately 1 second. The following window will then be displayed:

Figure 11: Pressure Test Layout

After a 5 second settling period, valves will be activated to introduce the test pressure to the AOA+ (ALPHA+) pressure port. The FTK100 will read the pressure data sensed by the DUT across the CAN AERO connection and record data from its own internal reference pressure sensor for a period of five seconds. After this sampling period, the valves are switched to disconnect the AOA+ port and return it to ambient atmospheric pressure, and simultaneously connect the internal pressure plenum to the AOA- (ALPHA-) port. During the following 5 second settling period, the pump is given ability to re-engage and recharge the plenum if necessary. If this occurs, a further 5s settling period is introduced before data is collected from both the DUT and reference pressure sensor. This process continues through all pressure ports in the following order: AOA+, AOA-, AOS+ (BETA+), AOS- (BETA-), Pitot-Static. After data has been collected for the pitot-static test, the valves switch to change the direction of air-flo w between the pump and internal plenum so as to generate a vacuum. The pump runs and takes the plenum pressure down to approximately 90kPa. The static pressure

port is then activated and now the internal reference barometric sensor is sampled concurrently with data from the DUT access across the CAN AERO network connection.

The status bar will display status information as the test progresses through all stages.

Once the test is complete, mean values are computed from the approximately 150 data points sampled during each stage of the test. Mean values from the reference sensors, the DUT and the differences between them are displayed in a tabular format:

If there is any leakage inside the calibration fixture, time-out error will be displayed during the pressure test as the device can’t obtain the pressure results within the time limit. Gently push the calibration fixture further until all the O-rings in the fixture are fully engaged with the boom.
