"A 'Zero Stage' for the Saturn IB Launch Vehicle."
To meet the demands of increasing payload size and weight, and to fill the large payload gap between the Saturn IB and Saturn V, a number of methods of uprating the Saturn IB have been studied by NASA and Chrysler Corp. of providing increased payload capability is discussed in this paper. Four 120 in. United Technology Center UA-1205 solid propellant motors, originally developed for the Air Force Titan III program, are clustered around the S-IB first stage of the Saturn IB launch vehicle. These four solid propellant motors provide the total thrust for liftoff of the vehicle, with S-IB stage ignition occurring just prior to burn-out and separation of the solid propellant motors. The term "Zero Stage" is applied to this added stage. -
"A Comparison of an MIT Explicit Guidance Principle with MSFC Iterative Guidance."
From the summary: "Both [guidance] schemes steer toward a specified end point. The MIT scheme uses thrust to cancel out the effective gravity, a nonlinear term, which may be inefficient in certain cases. The MSFC scheme is more closely connected with calculus of variations and optimization theory in a reasonable degree of approximation." -

"A Hybrid Simulation for Dynamic Verification of Saturn Guidance and Control Subsystems."
This paper presents a discussion of a hybrid simulation used to dynamically verify the Saturn Guidance and Control subsystems. First, the Saturn vehicle is briefly described to provide background information.

After a brief description of the actual G and FC System operation, simulation models of the G and FC components are considered in detail. This is followed by a discussion of the model assignment to a particular computer (digital or analog) and justification for making that assignment. Finally, results of the AS-204/LM1 hybrid simulation studies are briefly considered with mention of the actual flight data. -
"A new telemetry technique."
A technique new to telemetry is discussed which promises to alleviate an enigma facing the telemetry engineer : How to adequately transmit the avalanche of vibration and other wideband data desired in the development phase of large missiles and launch vehicles. The data channels are stacked in the frequency spectrum as single sideband subcarriers which frequency modulate the RF carrier. The system design utilizes to advantage the statistical properties of vibration data to achieve maximum data transmission efficiency from the available RF carrier deviation. However, in contrast to proposed statistical predigestion techniques, the data is transmitted in raw form. -

The principal concern of this study has been the identification of further research origins of LANCE and the 46 documented events are its major product. A further concern and obligation of this study has been to provide HINDSIGHT with some additional data on the research phenomenon including some further observations on the nature and route of research utilization.; FOREWORD: The purpose of this report is to present a survey of fundamental research contributing to the successful development of the LANCE weapon system. Included in this report are discussions of research inputs to a number of LANCE systems and technology areas. The circumstances of these research contributions to LANCE are discussed. The implications of these examples of research utilization are analyzed and some general observations and conclusions on the research payoff phenomena are given.

The introduction notes, "The Saturn V launch vehicle is being developed by the National Aeronautics and Space Administration's George C. Marshall Space Flight Center for Project Apollo; Saturn I and Saturn IB vehicles are providing the early testing and support for Project Apollo. The nerve center of the Saturn is its guidance and control system. An airborne digital computer provides the link which closes both the guidance and control loops,making verification of the flight computer program of vital importance. During a powered flight this onboard digital computer program can be divided into four major parts:a) guidance, including navigation, b) control, c) vehicle sequencing, and d) computer telemetry." -
