Description

This is a modification to the synopsis entitled Angle of Attack for Wind Tunnel Models 3-170583 which was posted on February 27, 2001. You are notified that the following changes are made: This corrects typographical errors concerning the technical measurements found in the original solicitation. Replace specification A. 7-9, A. 12-14, and B.1 with the following specifications: A) AOA Sensor Package 7) A 10% variation in either or both supply voltages shall shift the bias less than 30 microG and shall shift the scale factor less than .01%. 8) Unfiltered output noise shall not exceed 8 microG RMS below 10 Hz and 80 microG RMS between 10 Hz. and 500 Hz. 9) Nonlinearity and hysteresis shall not exceed 35 microG over a range of 1 1 G. 12) Stability: at a constant temperature of 71 C, no reading with package level shall differ from any other reading with package level by more than 80 microG for four hours (after a 30 minute warm-up). Sensitivity shall not shift more than .03% during the same four hour period. 13) Rectification: 4G RMS random vibration (constant energy per hertz of bandwidth) in any axis shall cause an output shift of 100 microG or less in the 50-5000 Hz band. Sinusoidal acceleration of 3 G in any axis shall cause: a. an output shift of 90 microG or less in the 50-1000 Hz band. b. an output shift of 500 microG or less in the 1000-2000 Hz band. c. an output shift of 1000 microG or less in the 2000-5000 Hz band. 14) Permanent bias shift caused by any environment in these specifications shall be 180 microG or less. B) Signal Conditioner 1) Shall have an internal DC power supply capable of providing both +15 Vdc and -15 Vdc relative to power and AOA signal common and both supplies shall provide sufficient current to power an AOA requiring a maximum current of 20 mA from each supply. The accuracy of both supply voltages shall be 11%. The due date for receipt of quotes is not extended.
