New Axon Modules Are First to Allow Actual-time FFT Processing of Excessive-Velocity Accelerometers and TEDS Onboard the Plane for Flight Take a look at Packages

European Take a look at & Telemetry Convention (ETTC) Toulouse, France (Sales space #20/21) – June 13, 2023 – Curtiss-Wright’s Defense Options division, at the moment introduced that it has expanded the capabilities of its Axon product household with the introduction of the brand new Axon ICP information acquisition module vary. The 2 Axon ICP modules, AXN/ICP/401/B/10V and AXN/ICP/402 (ADAU variations are additionally obtainable) assist scale back the time required to finish a flight check marketing campaign by enabling the in-module evaluation of excessive pattern price accelerometer measurements (that are essential for understanding and quantifying the vibration frequencies skilled by the airframe). Unprocessed uncooked accelerometer information requires giant quantities of restricted PCM bandwidth and limits the amount of vibration parameters, or different information, that may be telemetered. In distinction, the information evaluation outcomes, sometimes derived from FFT processing, use considerably much less of the obtainable PCM bandwidth.

By performing the evaluation of accelerometer information onboard the plane and sending solely the FFT outcomes over the PCM stream, flight check engineers can velocity up post-test information evaluation on the bottom whereas releasing further PCM bandwidth to telemeter extra vibration channels and different helpful information. For example, 12 ICP channels sampled at 8,192 Hz inside a 100-word broad minor body with 256 minor frames per 16 Hz main body would require 24%% of an obtainable PCM body. As compared, the highest 32 FFT frequencies and respective powers per channel will solely require 3% of the obtainable PCM house.

The AXN/ICP/401/B/10V module (ADAU model: AICP-412A-1) helps 12 channels with a sampling velocity of 25 ksps. The AXN/ICP/402 (ADAU model: AICP-404A-1) helps 4 channels at 100 ksps. These modules can carry out an FFT on all of their channels, with the ensuing information, together with the unique sampled information, obtainable as output parameters.

The Axon ICP modules and their ADAU equivalents additionally present assist for TEDS (transducer digital datasheet). TEDS permits a small quantity of knowledge to be saved on the sensor, which in flip could be learn by configuration software program and allow the automated entry of configuration information, which saves time and reduces human error. TEDS additionally permits calibration information to be saved, which, for instance, may function a superb fast pre-flight verify to substantiate that each one sensors are linked appropriately.

The Axon product household is probably the most superior airborne information acquisition system obtainable at the moment, providing low SWaP with the perfect function set, information acquisition, and thermal efficiency available on the market. The Axon product household builds on Curtiss-Wright’s heritage because the main provider of rugged dependable information acquisition for aerospace purposes.

Axon’s future-proof design, utilizing a high-speed serial backplane (1 Gbps devoted hyperlink per module) ensures future excessive information charges are supported. Its low SWaP design means it may be situated in tight areas and operates reliably with out requiring cumbersome heatsinks. This design additionally permits any of the Axon household consumer modules to be positioned in ultra-miniature “Axonite” housings and situated remotely, separated from the chassis by as much as 10 meters. Finding information acquisition nearer to the sensors can considerably lower the set up time and value of the instrumentation whereas concurrently decreasing wiring weight. Axonites may provide important system value saving in bigger installations by decreasing the variety of DAUs required in distant areas and thus slicing down on further chassis, controller, and energy provide prices.

Axon AXN household modules are optimized to be used with Curtiss-Wright’s Acra KAM-500 network-based DAUs and DAS Studio software program, whereas Axon ADAU modules are optimized to be used with Curtiss-Wright’s TTC networked-based DAUs and TTCWare Software program.
