ABSTRACT:
A dome for protecting energy responsive instrumentation in a missile is disclosed which utilizes a plurality of wedge shaped transparent elements mounted in a polymer matrix. The transparent elements are arranged so that aerodynamic pressure acting on the dome compresses each transparent element and prevents dome implosion. Individual elements may crack under excessive aerodynamic load, but are held in place by adjacent elements and by aerodynamic pressure, and retain their optical transmissivity during final trajectory to the target.
