About this file
This is a Statement of Work for the fabrication of rotor blades for performance testing at NASA Ames' Planetary Aeolian Laboratory. The contractor is required to manufacture three sets of five ROAMX blades (15 blades total) using existing molds and ply layup instructions previously generated by Sensenich. The first blade set will feature outboard ply orientation changed to 45 degrees, while the subsequent two sets will have TBD (to be determined) structural adjustments based on test results from the initial set and collaborative discussions with the awarded contractor.
The contractor must meet strict tolerance requirements, including maintaining outboard thickness to 0.005" or better, preserving a minimum outboard thickness of 0.009" while maintaining fibers (not only resin), and holding root thickness to +/- 0.005" tolerance without machining. The work will be performed at the contractor's facility. The first blade set shall be delivered within 15 weeks after contract award, with subsequent blade sets to be discussed and all deliverables completed within 8 months after contract award. The government will provide CAD files and manufacturing instructions upon request.

STATEMENT OF WORK
1. Introduction/Background: Three sets of rotor blades with varying structural properties require fabrication for performance testing on the ROAMX Hover Test Stand (RHTS)
2. Scope of Work: The purchase request (PR) will cover the manufacture of three sets of five ROAMX blades. The first set will have a layup that is a slight deviation from the original ROAMX layup, and the subsequent sets of blades will vary depending on test results from the first set and discussion with contractor.
3. Objectives: The provision of rotor blades for testing with the RHTS in the NASA Ames Planetary Aeolian Laboratory.
4. Description of the Work/Contractor Tasks:
The three blade sets will be manufactured using existing ROAMX molds and ply layup instructions, which Sensenich generated and used to manufacture the original ROAMX blades. The three sets of blades may have slightly different structural and layup properties, which will be evaluated between manufacturing of blade sets and will be an iterative process discussing with the awarded company.
Tolerances:
1. Hold thickness outboard to tolerance of 0.005” or better.
2. Maintain thickness outboard of 0.009” (thinnest ply) – maintain the fibers (not only the resin).
3. Maintain root thickness to +/- 0.005” tolerance (do NOT machine).
4. See below for aluminum root tolerances.
5. Deliverables: The following items will be delivered:
• ROAMX blade set with outboard ply orientation changed to 45 degrees (qty 5)
• ROAMX blade set with TBD structural adjustments to be made (qty 5)
• ROAMX blade set with TBD structural adjustments to be made (qty 5)
• (Total of 15 blades)
6. Government Provided Information: CAD files and manufacturing instructions provided on request (previously provided).
7. Place of Performance Contractor facility
8. Period of Performance The first set of blades shall be delivered within 15 weeks after contract award date.
Subsequent blade sets shall be discussed and all blade sets shall be delivered within 8 months after contract award.
