DESCRIPTION OF REQUIREMENTS:

Tire Pressure Mapping Sensor Pad

1. Description of Requirements:

The tire pressure mapping sensor pad is required to measure tire pressure for one-side of the main landing multi-wheel gear for the C-17, F-15, KC-46, and B-21 military aircraft. Specifically, the sensor pad measure tire pressure that have: (a) tire width up to 24-in, (b) minimum tire pressure 750-psi, (c) weights up to 75-kips, and (d) and data collection rate minimum 25-kHz.

The tire pressure mapping sensor pad must also meet the following requirements:

a. Sensor Thickness Range, (in.): [0.004 - 0.008]

b. Data Sampling Rate: Minimum 20,000 frames per second (880,000 points per second per sensor, with simultaneously 16 sensor sampling capabilities).

c. Operating Temperature Range, (°F): minimum [ -40-140] and capable of [-40-392°F]

d. Sensor Border Width: Borderless multi-sensor arrays configuration for capturing main landing multi-wheel gear tire pressures as noted for aircraft above.

e. Direct Measure (non-extrapolated) Sensor Pressure Range, (psi): [1,500 - 25,000]

f. Sensor Plastic Deformation Minimum Limit, (psi): 10,000

g. Sensing Area Range, (sq. ft.): minimum 19-ft with expansion capabilities 28.5-ft

h. Software:

i. View pressure distribution dynamically in real time

ii. Record dynamic pressure

iii. ASCII data export capability for importing data into 3rd-party programs such as Python, Excel, JMP, and/or MATLAB.

iv. Image export capability for importing data into 3rd-party programs such as png, jpeg and/or tiff, etc.

v. Single point calibration (pressures and forces displayed in engineering units)

vi. Multi-point calibration (pressures and forces displayed in engineering units)

vii. Multi-point equilibration (normalize sensor output over a wide range of pressures)

viii. Pre-Post loading reconciliation using digital Zero Taring Function

ix. 2-D and 3-D pressure mapping viewer with statistical distribution determination for effective multi-wheel gear tire stress bulb analysis.
