Abstract:
An assessment methodology has been developed for - use during the
conceptual/preliminary design phase to quantify the effectiveness of newly designed
aircraft. The effectiveness is measured by a squadron Sortie Generation Rate (SGR). Key
elements of this methodology were the establishment of link parameters between
design synthesis and the main effectiveness disciplines. These were Reliability and
Maintainability (R&M), Survivability / Vulnerability and Acquisition Cost. A
programmable solid modeller was used to create a solid CAD assembly of the aircraft
critical components. A ray tracing technique has been used to develop an interactive
vulnerability assessment tool. A Mission Simulation Model (MSM) has been developed
which typically simulates the operation of a squadron of aircraft and gives the operational
activities such as flying sorties and maintenance actions. The methodology has been
validated based on real data from recent conflicts. The application aspects of the
methodology have been demonstrated by quantifying the effectiveness of two recent
combat aircraft.
