Descriptions of files in the CYBERROC directory: MOTORMOD.ZIP Title : ROCKET MOTOR DATA GENERATOR FOR FLIGHT SIMS V2.00 MOTORMOD.ZIP contains the program MOTORMOD and its documentation, data, and example files. MOTORMOD is a utility for the creation, viewing, and editing of motor data files for iterative-type altitude simulations. Version 2 adds the ability to exchange data files between ALT4, RSIM, and RASP formats; and data can be graphically viewed and compaired on-screen. MOTORMOD editing features allow the creation of complex clustered motor combinations and other data manipulation methods. Requires IBM/VGA. MOTORSIM.ZIP Title : ROCKET MOTOR INTERNAL BALLISTICS SIMULATION V0.40 MOTORSIM.ZIP contains the files MOTORSIM.EXE, MOTORSIM.DOC, and a data file PROPELL.DAT. MOTORSIM is a simple rocket motor internal ballistics simulator. Given propellant characteristics, grain, core, and nozzle dimensions, MOTORSIM will produce an on-screen thrust-time curve. A unique feature allows the affect of varying motor dimensions to be viewed on multiple overlaid plots. Requires IBM/VGA. Highly preliminary version. MOTORTUT.ZIP Title : MOTORTUT: Rocket Motor Animated Tutorial V1.10 MOTORTUT is a rocket motor tutorial program that presents a series of animated screens dealing with model and high-power rocket motors. It details the internal dynamics of several motor types, plus ignition systems, motor nomenclature and classifications, and thrust-time curves. MOTORTUT requires IBM/VGA. NTSHAPE.ZIP Title : NOSECONE/TRANSITION SECTION SHAPE GENERATOR V1.10 NTSHAPE.ZIP contains the program NTSHAPE.EXE and its doc file NTSHAPE.DOC. NTSHAPE is a utility for viewing nosecone and transition section shapes, including some shape types that are not often seen on model or HP rockets due to their complexity. NTSHAPE will also generate a listing file of station diameters for any displayed shape that can be used for turning a nose cone or machining a mold. STAGEA4.ZIP Title : DATA FILE MERGER FOR ALT4 STAGING V1.20 STGA4.ZIP contains the program STAGEA4.EXE plus .DOC and example data files. STAGEA4 is the utility RAS forgot... an add-on for the Rogers Aeroscience ALT4 program, that allows merging of separate booster and sustainer simulations, allowing viewing of a single graph covering the entire flight. VCP151.ZIP Title : VCP Version 1.51 Barrowman CP/CG Calculator VCP is a Windows Visual Basic program that implements the Barrowman center-of-pressure equations in a specialized spreadsheet form. It draws the entered rocket on screen as you work to verify data entry. File save & load. Prints graphic stability report. Includes example library files of many current kits. GEODESIC.ZIP Title : Geodesic Tracking Equations - General Form GEODESIC.ZIP contains a PASCAL source file and sample .EXE of the general form of the Geodesic tracking equations. This form properly accounts for differences in tracker altitudes by not making the assumptions in the derivations that restrict the commonly used geodesic equations to a level tracking geometry. GEODESIC.C C source code equivalent of pascal program GEODESIC, provided by Warren Massey.
