AERODYNAMIC FAIRING

摘要

An aerodynamic fairing (16) which is mountable on a strap on solid rocket motor (SRM) is configured such that in flight aero-acoustic effects are significantly reduced with regared to the launch vehicle (10) which the SRM is mounted and other external apparatus. The aerodynamic fairing (16) is configured to include a leading edge which is substantially flat and provides the forward intersection between the inboard and outboard sides of the fairing. On mounting the fairing and SRM to a launch vehicle (10), the inboard surface is closest to the launch vehicle (10) while the outboard surface is further away. With regard to the aerodynamic fairing (16), the transition rearward from the leading edge to a base end, the inboard surface is initially flat and transitions to the cylindrical shape of the SRM. The outboard surface of the fairing is configured such that it has a profile of a canted ogive which extends from the leading edge and smoothly transitions to the cylindrical shape of the SRM at the base end.
