STATEMENT OF WORK FOR MACH BURST DIAPHRAGM

I. PURPOSE

The purpose of the effort is to fabricate hardware for the Arnold Engineering Development Complex (AEDC) Tunnel 9 Diaphragm Area in order to provide replacements for used hardware.

II. SCOPE

The scope of this effort is to fabricate Tunnel 9 Diaphragm Area Hardware to meet the operational needs of the Tunnel 9 facility. The fabricator shall manufacture the items listed in Table 1 according to their corresponding drawings. The fabricator shall supply a written material certification for the material used to fabricate the burst diaphragms which shall include chemical composition, yield strength, tensile strength, modulus of elasticity, and percent elongation. Prior to machining grooves shown in Drawing 77-1088-12, the fabricator shall provide the material certification to AEDC to allow AEDC to modify the remainder under the groove dimension to ensure proper diaphragm operation in the AEDC facility. The fabricator shall supply a copy of the required reports specified in each drawing. The fabricator shall supply a 100% inspection report for each part. The fabricator shall supply a certificate of compliance for each part. The fabricator shall mark each part with layout dye the part number, thickness, remainder from the corresponding drawing as well as an identification number in the range shown for each item in Table 1. Upon completion, all parts will be shipped to the Tunnel 9 facility, Arnold Engineering Development Complex-White Oak, 10905 New Hampshire Ave, Silver Spring, MD 20903-1050. Drawings and parts subject to distribution statement as contained in the drawings.
