Pacific Scientific Energetic Materials Co. established an IR&D program to develop a method of severing polycarbonate as it is being proposed for use in high performance aircraft canopy transparencies.

We have performed nearly 300 tests and have demonstrated reliable methods of severing thickness from .25 to .75 inch with pyrotechnic charges secured to the inner surface of the canopy transparency.

Successful testing has been performed throughout the temperature range of -65° to +200° F. The size, form, installation and materials used all have an effect on the performance of the severance system.  PSEMC testing has demonstrated repeatable performance on the various configurations tested.  Canopy severance testing has been successfully performed and noise level data has been collected.

Based on our studies,   we believe this product is ready for introduction to high performance aircraft to ensure immediate reliable egress of aircrew members from a disabled aircraft.
