:'lii:ilì -jr'ìr,l LTV Astronautics has been participating in 'it I production and launching of ü:l the development, the Scout solid propellant vehicle for over , t:i four years. During this time, Scout vehicles have been utilized in probe, re-entry and ì ,ti orbital missions including the launching of Explorer IX, the first satellite put in orbit Er¡Ë by a solid propellant booster vehicle.

.J h, This is the second revision of a report which :il was prepared to familiarize users and po- -:x performance r.1., tential users of the Scout and its þ-:l capabilities, It hâs been "up-dated" to reflect :l the improved performance ofthe Scoutvehicle of a new fourth stage motor' il through the use -T the ABL X-258.

t-2 g MISSIOI\TS

The purpose cf Scout vehicles is to boost payloads for orbital, probe and re-entry missions at a lower vehicle cost than is possible by any other means.

This goal has been met through the use of proven and tested concepts, components, and procedures. Design simplicity keyed around the solid propellant motors and a modular concept result in short, simple count- downs and lends flexibility to launch operations.

Complete suþporting systems ernbodying the same principles are avail- able with the vehicles. Launch sites at Wallops Island and the Pacific Missile Range are now available. I:

The control forces for these two stages are provided by hydrogen t* peroxide reaction jet motors which are operated as an "on-off" system.The s motors are so placed that moments are set up âbout each of the three axes: i pitch, yaw, and roII. The motors are mono-propellant and utilize 90 percent hydrogen peroxide (H2O2). Propellant pressurization is provided by com- ..$ pressed nitrogen (N2) gas.

POWER AND IGNITION SYSTEM LI To achieve high reliability, dualized ignition systems have been em- ployed. Safety features have been designed into the systems to prevent l accidental or premature firing of the rocket motors. Dual squibs are used in all ignitors, dualized. Eachoneofthe dual squibs is in a separate circuit and is connected to a separate battery so that an electrical com- fl t_ ponent failure wiII affect only one circuit. Ignition of the first stage motor is accomplished by a direct electrical signal provided by launch block- F house command. Second, third, and fourth stage ignitions are coptrolled [, by the gtidance program timer. The system provides for the foliowing firing sequence: first stage ignition from blockhouse command, 2nd T stage ignition, 3rd stage ignition and 4th stage heat shield ejection, and 4th stage ignition and spin motors. The same primary power source is utilized by the ignition and destruct systems. tt

The Destruct System provides capabilities for positive thrust termination of the first three stages to avoid a live uncontrolled vehicle impacting on or near the ground launch facilities or in populated areas. The system provides two methods of destruct, the command method operated by RF link and the auto- matÍc method utilizing lanyard and pressure actuated switches. The system is dualized, using two parallel linear charges per motor which can be detonated by either of two separate dual safe-arm units. The system may be armed or safed remotely frorri the blockhouse, Electrical safing is provided for ground operation. Destruct of the vehicle may be accomplished by RF link at the dis- cretion of the range safety officer or by automatic link if the second stage separates prematurely during first stage burning. Destruct capabilities for the payload can be incorporated if desir-ed. A simplified diagram of the system is depicted below.

The pertinent details ofthis payload compartment are shown on the adjacent page. When Payload and 4th stage separation is not re- : quired, additional payload volume is available. The heat shield !!r which dictates the compartment is of fiberglas honeycomb sandwich construction with a stainless steel nose cap. It is designed to carry fourth stage vehicle Ioads and to keep compartment temperatures within specified limits. Abumper between the heat shield and motor - keeps the payload from hitting the heat shield under high load con- i ditions and transfers lateral inertial loads fromthe motor case to - the heat shield.

The heat shield is fabricated in two half shells with a stainless a ¡ steel nose cap attached to the tower side of the shell and with Í steel half-rings at the base to accept ajoining clamp. Shell restraint iÌ is provided through a series of over center 'latches along the

separation plane and a joining clamp at the base. The latches {. and clamp are triggered and released by drawbars attached to ¡Ì bellcranks and a ballistic actuator near the forward end of the heat shield. Upon release of the latches and clamp, Iatch contained springs force the heat shield apart. The separation plane lies along the pitch axis.

SPIN ENVIRONMENT The spin environment for various sPIN RATE VS 4TH STAGE MOMENT OF INERTIA VÀCUUM fourth stage total moments of inertia is shown in the adjacent graph for vehicles incorporating the cold (spring e jection) separation system. For total roll moment of inertia, add payload roll inertia to results inthe Roll Inertia Table below. The effect of spin rate on final stage ftightpath deviation indicates a desired mini- mum of 140 RpM. The spin rates shown in the adjacent graph are those which wiII occur at fourth stage ignition. As a result of the internal gas dynamics, the spin rate at fourth stage burnout wiII be approximately lLls greater than those at ignition. The table shows typical Scout roll moments of inertia for a fourth stage.

UMBILICAL PROVISIONS

Although payload umbilical doors may be positioned within a horizontal angular location +15'of the yaw axis centerline on the tower side, PaY- loads are requested to use toP centerline Yaw axis Positive for a more reliable umbilical operation. Vertical Positioning is normallY within the area tretween sta. 51.0 and sta, 22.0 as shown in the adjacent illustration. The doors ånd related hardware protrude inside the con- tour 1,12 inches. Standard door di- mensions are 5 x 5 inches.

The umbilical electrical connectors feature Bendix "twist/pull" quick disconnect plugs with modifications to provide reliable lanyard uncouple. Shock pull-off is set at 45 +5 pounds'

Heating or cooling facilities can be incorporated for temperature con- trol of the paYload, usable uP to launch. Entrance of conditioning air supplied from the launch comPlex unit enters at the same angular Iocation as the umtrilical, with dis- connect either prior to or simultane - ous with the umbilical connector re - traction. The cooling sYstem will provide humidity controlled air at selected temPerature between am- bient and 40'F.

The heat shield and stainless steel nose cap protects the payload from aerodynamic heating during ascent and carries fourth stage vehicle loads for all launch angles from a minimum of 78" to nearly vertical. Added protection is afforded by a gold coated radiation shield located on a station-plane at the aft end of the nose cap.

Nose cap and heat shield temperature vs. time are shown on the following page. Heat shield temperature gradient vs. time forboth cylindrical and ãonicat sections are depicted on page 4-11 and 4-12. The trajectory below is used for each of the Plots.

These basic requirements are considered to be a mini- mum for the demonstration of the structural, mechanical, and electronic integrity of the spacecraft during flight ascent. I i DYNAMIC BALANCE

The sinusoidal vibration test shall be conducted by sweeping at a logarithmic rate from the lowest to the highest frequency once for each range specified. The random vibration test shall be of random peak accelerations over the frequency ranges specified.

Significant orbital, probe, and re-entry performance im_ provements are achieved with theuseof improved motors which are under development or being planned for de_ velopment,

This program currently has under development an im_ proved second stage motor which is a *oãifi"d version of the Castor motor presently being used. Improvements to the other motor stages have alreadybeen inãorporated. The ABL X-258 recenfly replaced the X_24g as the standard fourth stage motor. Other changes have been the incorporation of a new first stage motor, the Algol IIA, which was a development of the Algol ID originally used, and the X-259 which was a development of the X_Zb4 originally used as the Scout third stage motor.

Prior to detail planning to take advantage ofthe increased performance and payload capability resulting from the use of improved motors, inquiries should be made to determine the time phasing of these developments into the standard Scout vehicle
