South Apron Blast Shields

FNWZ 25-0166

4.1.1 Blast Deflectors shall be installed on existing concrete. Existing concrete has a minimum thickness of 16”. Lynnco "Epoxy-Locked" anchors, with Lynnco No. 22 Epoxy Resin were used to lock in place the existing blast deflectors.

5.1 BLAST DEFLECTOR ASSEMBLY:

5.1.1 All components will be assembled by bolting together with flat washers, under heads and nuts. Welding, brazing or burning of holes is not permitted. All nuts and bolts will be tightened to torques specified by manufacturer.

6.1 BLAST DEFLECTOR FINISH:

6.1.1 All bolts, nuts and washers will be cadmium or zinc plated. All struc­tural members, parts, and corrugated metal will be hot dip galvanized with a minimum coating of 2.0 oz. zinc per square foot of surface. Painting of gal­vanized surfaces is not required, but any galvanized surface badly scratched or marred, will be re-galvanized or otherwise repaired to the satisfaction of the Contracting Officer. 6.1.2 Contractor shall paint the corresponding aircraft parking position number on the front of the blast deflectors. The Contactor shall provide a 2’x2’ number sign mounted 15’ above the concrete at the midpoint on the backside of the blast deflector. Markings/sign shall follow details 2 and 8 on sheet C2 of the attached drawings.

7.1 BLAST DEFLECTOR ALTERNATIVES:

7.1.1 At the option of the Contracting Officer, and as specified in Paragraph 2, the Contractor may substitute an alternate type of blast deflector, providing that the following information and data is submitted, prior to the time of bid opening and approved in writing.
7.1.2 Contractor will submit for approval a tabulation of results of full-scale instrumented field tests witnessed and certified by an accredited testing laboratory, in which proposed alternate is subject to the intermediate throttle power of similar engines totaling # 30,000 afterburner thrust @ approx. 90 feet distance from the leading edge of the deflector measured along centerline of bast impingement. Tabulation must show the maximum pressure in psi, temperature in degrees F., vibration frequency in CPS, and vibration amplitude in inches, taken at the centerline of blast impingement on deflector. The results of all such readings may not be greater than the readings submitted for the specified deflector, for each corresponding item.
7.1.3 Contractor must submit results of smoke-pot tests behind similar deflectors, demonstrating that smoke and
