Hood Deployment Controls
The hood deployment controls are pyrotechnic devices installed on the body mounted part of the hood hinge assembly. When the hood deployment controls are deployed, interface plates on the actuators contact reinforced areas on the hood hinges, and raise the rear of the hood.
The hood hinges incorporate a number of leaves. This includes a leaf attached to the body, an intermediate leaf and a leaf attached to the hood. During normal operation the hinge opens and closes using the hood and intermediate leaves. These are attached together by a shear pin. When the actuators are fired the shear pins fail. This allows the hood and intermediate leaves to separate and deploy the hood upwards.
The hinges deform during the deployment process and will need to be replaced.
