# PROGRAM NAME: 1/ACCS
|
|
|
|
|
# PROGRAM WRITTEN BY: BOB COVELLI AND MIKE HOUSTON
|
|
|
|
|
# LAST MODIFICATION: FEB. 14, 1969 BY G. KALAN
|
|
|
|
|
#
|
|
|
|
|
# PROGRAM DESCRIPTION:
|
|
|
|
|
# 1/ACCS PROVIDES THE INTERFACE BETWEEN THE GUIDANCE PROGRAMS AND THE DIGITAL AUTOPILOT. WHENEVER THERE IS A
|
|
|
|
|
# CHANGE IN THE MASS OF THE VEHICLE, IN THE DEADBAND SELECTED, IN THE VEHICLE CONFIGURATION (ASCENT-DESCENT-
|
|
|
|
|
# DOCKED), AND DURING A FRESH START OR A RESTART, 1/ACCS IS CALLED TO COMMUNICATE THE DATA CHANGES TO THE DAP.
|
|
|
|
|
#
|
|
|
|
|
# THE INPUTS TO 1/ACCS ARE MASS, ACCELERATION (ABDELV), DEADBAND (DB), OFFSET ACCELERATIONS (AOSQ AND AOSR),
|
|
|
|
|
# STAGE VERIFY BIT (CHAN30, BIT2), DOCKED BIT (DAPBOOLS, BIT13), DRIFT BIT (DAPBOOLS, BIT8), USEQRJTS (DAPBOOLS,
|
|
|
|
|
# BIT14), AND SURFACE FLAG (FLAGWRDB, BIT8), AND CH5MASK.
|
|
|
|
|
#
|
|
|
|
|
# 1/ACCS COMPUTES THE JET ACCELERATIONS (1JACC, 1JACCQ, 1JACCR) AS FUNCTIONS OF MASS. 1JACCU AND 1JACCV ARE
|
|
|
|
|
# FORMED BY RESOLVING 1JACCQ AND 1JACCR. IN THE DESCENT CASE, THE DESCENT ENGINE MOMENT ARM (L, PVT-CG) IS ALSO
|
|
|
|
|
# COMPUTED AS A FUNCTION OF MASS. THE RATE OF CHANGE OF ACCELERATION DUE TO ROTATION OF THE GIMBAL (ACCDOTQ,
|
|
|
|
|
# ACCDOTR) IS ALSO COMPUTED IN THE DESCENT CASE.
|
|
|
|
|
#
|
|
|
|
|
# AFTER THE ABOVE COMPUTATIONS, THE PROGRAM 1/ACCONT COMPUTES THE RECIPROCAL NET ACCELERATIONS ABOUT THE P, U,
|
|
|
|
|
# AND V AXES (2 JETS FOR P-AXIS, BOTH 1 AND 2 JETS FOR U AND V AXES), AND THE RECIPROCAL COAST ACCELERATIONS ABOUT
|
|
|
|
|
# THE P, U, AND V AXES. THE ACCELERATION FUNCTIONS (ACCFCTZ1 AND ACCFCTZ5) ARE ALSO COMPUTED FOR THESE AXES. THE
|
|
|
|
|
# FIRE AND COAST DEADBANDS AND AXISDIST ARE COMPUTED FOR EACH AXIS. FLAT AND ZONE3LIM, THE WIDTH AND HEIGHT OF THE
|
|
|
|
|
# MINIMUM IMPULSE ZONE, ARE COMPUTED. 1/ACCONT ALSO SETS ACCSWU AND ACCSWV, WHICH INDICATE WHEN 1 JET ACCELERATION
|
|
|
|
|
# IS NOT SUFFICIENT TO PRODUCE MINIMUM ACCELERATION. AT THE COMPLETION OF 1/ACCS, THE ACCSOKAY BIT IS SET.

|
|
|
|
|
# PURPOSE: THIS SUBROUTINE PROVIDES A SINGLE-PRECISION MACHINE LANGUAGE DIVISION OPERATION WHICH RETURNS
|
|
|
|
|
# (1) THE QUOTIENT, IF THE DIVISION WAS NORMAL.
|
|
|
|
|
# (2) NEGMAX, IF THE QUOTIENT WAS IMPROPER AND NEGATIVE.
|
|
|
|
|
# (3) POSMAX, IF THE QUOTIENT WAS IMPROPER AND POSITIVE OR IF THERE WAS A ZERO DIVISOR.
|
|
|
|
|
# THE CALLING PROGRAM IS PRESUMED TO BE A JOB IN THE F BANK WHICH CONTAINS DVOVSUB. E BANK MUST BE 6.
|
|
|
|
|
# THE DIVISOR FOR THIS ROUTINE MAY BE IN EITHER FIXED OR ERASABLE STORAGE. SIGN AGREEMENT IS
|
|
