1.0 Introduction

1.1 Background

The Air Vehicle/Stores Compatibility (AVSC) sub-Division of the Manned and Unmanned Air Vehicle Evaluation Division (AIR-5.1.6) is responsible for evaluating compatibility between USN/USMC aircraft and the stores they employ for tactical aircraft missions. Conducting weapon separation flight tests is a critical component of that evaluation. One of the primary methods used to evaluate weapon separation characteristics is to gather data with inertial measurement units (IMU) installed in the weapons/stores that are released.

1.2 Scope

The AVSC sub-division has a requirement for a contract vehicle with provisions to purchase and re-calibrate 6DoF IMUs and purchase associated hardware. Recalibrations are to be conducted in accordance with OPNAV INST 3960.16A.

2.0 Applicable Documents

4.0 Acceptance Criteria

4.1 General Acceptance Criteria

All hardware, software, documentation shall be inspected by the Government at destination. All hard ware components shall be designed to prevent FOD once installed in weapon, store, or aircraft. Up to one year shelf life is expected on all hardware prior to first use with the units functional for a minimum of ten years after date of delivery. The calibration of all hardware shall be valid at least one year and shall be recertified via the recalibration line items.

4.2 Certification of items for flight

The current testing completed for both to obtain US Navy flight certification and for data accuracy comparison to Photogrammetrics will be taken into account for in evaluation of proposals. For items where additional testing is required the cost for NAWCAD Patuxent River to perform the required testing will be added to the proposal price. Testing performed to date with proper documentation to obtain a US Navy flight clearance can be used to justify additional testing is not required.

4.3 IMU Calibration

The Calibration Record for each unit re-calibrated will be reviewed for quality assurance. The government will use the Calibration Record to determine how well the calibration matches the specification for new calibrations and how the new calibration matched the original for recalibrations. Any discrepancies will be reported to the contractor Program Manager immediately for resolution. If the problem cannot be resolved, the unit will be sent back to the contractor for rework.

5.0 Transition Period

5.1 Qualification Period

A 90 day qualification period prior to contract period will be available for certification of items for flight (Section 4.2). All items contained in proposal shall be available for testing at the start of the 90 day period. The qualification period does not include time for rework of items to meet flight worthiness standards and all question for certification of items should be addressed prior to start of the 90 day period.
