Simplified Input for Certain Aerodynamic Nose Configurations to the Grumman Quick-Geometry System (A KWIKNOSE User's Manual).

摘要

This report is a user's manual for a Fortran computer program KWIKNOSE which, for certain axisymmetric and nonaxisymmetric nose configurations, provides simplified geometric input to the Grumman QUICK-geometry system, which in turn provides geometric information to various numerical flow codes. For a wide variety in choice of input parameters, KWIKNOSE sets up the QUICK input for an arbitrary sequence of conical and ogival sections. In this process, KWIKNOSE performs the tedious computations necessary to locate the intersection points of successive arcs and to insert optional fillets or rounds over nontangent intersections. In addition, the code is capable of inserting arbitrary multiple slicing planes into the top, bottom, and side of the vehicle. Slicing plane intersections may be filleted or rounded. Thus, for a minimum of input and manual calculation by the user, KWIKNOSE is tailored to modeling the geometry of a sliced multiconic vehicle capped with an asymmetrically ablated nose. This manual provides check cases for the various geometry options, a description of input and output, and a listing of the source deck. (Author)
