1 INTRODUCTION

1.1 Scope. This statement of work (SOW) defines the Contractor’s efforts required to conduct non-destructive and destructive/functional testing of twelve (12) Government-Furnished Tomahawk Block IV F415 Engine Igniters (Pacific Scientific P/N 15936-05)).

1.2 Order of Precedence. In the event of inconsistency among requirements, the following descending order of precedence shall apply:

a. The Delivery Order including Statement of Work

b. Item Specifications

1.3 Background. FY23 will be the third Service Life Assessment Program (SLAP) testing of the Tomahawk Block IV F415 Engine Igniter. Testing shall be conducted with the process, procedures, and equipment consistent with those used in the latest revision of TP-15936. The Naval Surface Warfare Center, Indian Head Division (NSWC IHD), Code E14 manages the engine igniter program and will furnish the fleet-returned units.

The main objectives of the Engine Igniter Service Life Assessment Program (SLAP) include but are not limited to:

• Monitor any changes occurring with age in the physical condition and functional performance of the engine igniter after exposure to various deployment environments.

• Evaluate the effects of changes discovered on the engine igniter performance and predict a safe service life.

• Evaluate the feasibility of service life extensions.

1.4 Item Description. The Tomahawk Block IV F415 Engine Igniter, shown in Figure 1, is used to start the turbofan engine after rocket motor burnout at the start of the mission cruise phase. The pyrotechnic igniter consists of a one-shot, expendable design with an integral single bridgewire electric initiator and shielded leads. It contains ignition booster components and a main pyrotechnic charge. The Initiator, when electrically signaled, fires and ignites the ignition components which in turn ignite the main ignition charge. The burning products are discharged through an exhaust nozzle. The energy released ignites the fuel in the engine combustion chamber, aiding in engine start. This sealed device contains a mixture of zirconium, potassium perchlorate, boron, potassium nitrate, calcium chromate, and tellurium dioxide, and a sealed output load of zirconium, potassium perchlorate, magnesium, Teflon and Viton B.
