A SEQUENCE DIAGRAM ANALYSIS OF THE VANGUARD SATELLITE LAUNCHING VEHICLE

Abstract

The Vanguard Sequence Diagram method, introduced in AD-203 077, is applied to depict the operating sequence of the Vanguard Satellite Launching Vehicle. It relates vehicle systems oper-ATION DURING FINAL COUNTDOWN PREPARATIONS THROUGH LIFT-OFF, AND INCLUDES THE ENTIRE FLIGHT PROGRAM TO SATELLITE SEPARATION IN ORBIT. On the basis of information from the diagram, a brief system analysis of the vehicle is performed. The results are presented graphically and include: Vehicle state, state-transition breakdown; Vehicle component makeup; Launch program events; Flight profile of cumulative events and vehicle components remaining; Condensed sequence diagram; and Vehicle in-flight sequencing; flight-test results. A narrative description of the vehicle launch program is included by way of a verbal interpretation of the master sequence diagram. (Author)
