TI. TOPICAL sumaRy
A. FLIGHT TEST PROGRAM .

1. Progress on the SENTRY flight test program during the
quarterly period 1 July through 30 September included determination of
flight test objectives for all SENTRY/THOR flights.

2. A detailed test Plan for the first SENTRY flight was
prepared. Minor rescheduling has changed the launch date to 6 December,
two weeks later than originally planned. ‘The overall SENTRY program will
not be affected,

3. Modification and checkout operations on the first THOR-
boosted flight test vehicles were completed at Lockheed Missile Systems
Division during September. The vehicle was shipped from the Lockheed
Plant at Palo Alto to the Hazard test base at Sante Cruz where it will
undergo two hot firing tests prior to October shipment to the launch site
at Vandenberg Air Force Base.

4. Installation of launch and blockhouse equipment began the
week of 18 August in accordance with the schedule established for equip-
went installation and operations at the SENTRY/THOR launch complex at ‘
Vandenberg. A facility-checkout vehicle is being used for installation
checkout pending the arrival of the first SENTRY flight vehicle.

B. SATELLITE AIRFRAME SUBSYSTEM
SATELLITE AIRFRAME SUBSYSTEM

1. Final design of the first two SENTRY/THOR flight vehicles
was completed, and equipment installation design was underway on the re-
maining vehicles. SENTRY/THORs #1 and #2 underwent modification and check-
out at the Lockheed Missile Systems Division, where the spin aluminum tanks
were replaced in SENTRY/THOR #1. The installation included a fix on the

. ORidizer feed line to correct failure of a vibration absorbing bellows
under extended vibration tests, The aluminum bellows was replaced with a
steel bellows possessing better vibration characteristics. SENTRY/THOR #1
completed modification and checkout operations in September; SENTRY/TROR $2
checkout is still underway. (Figures 2, 3, and 4)

MEMORANDUM FOR THE RECORD
Aerio SUBJECT: Operational Planning for WS-117L

ner In a meeting attended by General Schriever,. General Ritland,
s$ Colonel Terhune, Colonel Sheppard, Colonel Evans, Celenel Oder,
4J T°” and Lt Golenel Boatman, 1000 hours, 2 July 1958, the folowing actions
were directed: .

ry) a. A letter will be sent to AFCGM which will furnish an AFBMD
draft of the ARS Preliminary Operational Concept, This will be the same
as that published by Hq USAF except that it will generalize on the defi-
ition of the hardware involved in lieu of the specific definitions in the
né Hq USAF version. The letter will advise that AFBMD is developing
jo a Data Utilisation Plan (DUP) for the R&D flights of WS-117L which will
Aud be submitted no later than the next revision of the WS-117L Development
Plan,

pun?

b. Ateam under WDT will be formed without delay to evolve the
DUP. The DUP will be responsive to the AFBMD POC, particularly

2 AN Pp r hb TB i,
Ea agrap!

wy ( c. The DUP will be submitted as the Operational Annex to the
0 next WS-117L Development Plan Submission.
d. SAC will be held responsible for submitting and supporting
their hardware and facilities requirements for operational use of WS-117L
and coordinating these requirements with AFBMD, The problem of es-
tablishing a schedule for such operations will be between CINCSAC and
Hq USAF, The manner by which SAC's requirements will be programmed
(AFBMD Development Plan vs normal SAC channels) will be determined
after these requirements have been reviewed,

e. The team referred to under paragraph b, above, will also :
; velop a National Operational Concept for WS-117L, Thia Concept will
nif

be more broad and inclusive than
fact it is under preparation will be ¢ ly held within AFBMD.

capsule is permitted to right itself eétcdyoamically. The retro-rocket
and spin rockets are jettisoned simultaneously efter burnout. During
reentry into the atmosphere, the biomedical capsule is protected by
ablative material. At approximately 50,000 feet a radar reflective
Parachute is opened. The remainder of the ablative material is jettisoned
and chaff is released. A radio beacon of greater than 50-mile range and
@ flashing light, visible for 10 miles during the day and 50 miles ‘at
night, is turned on. Lockheed RC-121 (Constellation) rader aircraft track
the descending Package and guide Fairchild C-119 aircraft to the recovery
Point. Recovery is wade'by the C-119 at or below approximately 10,000
feet by means of a cable loop with ‘hooks which nag the parachute canopy,
after which a winch will draw the collapsed parachute and capsule into

the aircraft. In the event that air recovery is not successful, surface
vessels will provide backup for water recovery.

2. An over-all recovery program test plan has been prepared.
Tests will be performed with weights simulating the recovery capsule.
Radar reflective parachutes and cheff will be tracked by the radar of the
RC-121 aircraft. Poll scale air and water recovery tests will be conducted
with the simulated capsule carrying flashing lights and radio beacons.
Biomedical experiments have been established for THOR/SEMTRY flights #3,

i. BRIEF OF PROGRESS

Flight test objectives have been determined for each of the ten
and biomedical test vehicles which comprise Program IIA. There
are presently nine different programs planned in the SENTRY development,
The ten SENTRY vehicles of Program IIA will have orbits between 160 and 2h0
statute miles.

The first THOR-boosted SENTRY test vehicle was moved from manufacturing
to checkout and modification at Lockheed Missile Systems Division. It is to
be moved to the Santa Crus, California test site on 27 August on schedule.

Development of all subsystems is proceeding on schedule.

Construction is proceeding as planned on the tracking and telemetry
stations at Cooke Air Force Base, California; Kaena Point, Oahu, Hawaii;
and nette Island, Alaska. ‘Initial occupancy at these sites is scheduled
for August. :

+
Fort Stevens, Tongue Point, Oregon, has been approved as the Northwest
tracking site. Recommendations have been made to use a bombing range near
Grenier Air Force Base, New Hampshire, for the Northeast site and the
deactivated Naval Air Station at Ottumwa, Iowa, for the Central site.

Cooke) Air Force Base are underway, with launch scheduled for 6 December.
The first flight test vehicle has been delivered by Lockheed to the Santa
Cruz test base where it will undergo hot firings in October before its
shipment to Vandenberg.

SENTRY/ATLAS design criteria has been altered to increase total veh-
icle weight and on-orbit weight. A change in the type fuel to be used in
SENTRY/ATLAS has resulted in performance increase allowing a gross weight
increase from 9,300 to 11,600 pounds and an on-orbit weight increase from %
approximately 3,500 to approximately 5,000 pounds.

411 SENTRY/THOR XLR61-Be-3 engines have been completed, acceptance
tested, and delivered to the Lockheed Missile Systems Division by Bell *
Aircraft Corporation. Propulsion systems scheduled for the first two
SENTRY/THOR flight test vehicles underwent hot firings at Lockheed, and
engine serial #4 was subjected to ten hot firings at the Santa Cruz test
base (Figure 1). Cold flow testing of this engine configuration is nearing
completion.

A prototype unsymmetrical di-mwethyl hydrazine (UDMA) engine under-
went two full firings with performance within specifications, resulting
in final assembly and delivery of the first UDMA engine to “Lockheed,

All subsystem development proceeded as scheduled. All components
of the auxiliary power subsystem for SENTRY/THOR #1 were received and
acceptance tested by Lockheed. Some Problems have been experienced in
the 2000 cycle and 400 cycle static inverters. A 400-cycle rotary inverter
will be used in SENTRY/THOR #1. Lockheed also received and tested 11
components of the guidance and control sybsystem for SENTRY/THOR #1 and a
number of components of this subsystem for SENTRY/THOR #2. Equipment develop-
went for the biomedical Program is on schedule. The Air Force School of
Aviation Medicine is acting as consultant to Lockheed on biomedical aspects
of capsule design and will supply and train test animals for this progran,
Detailed plans were established for reentry from orbit and recovery of the
biomedical package; an air recovery test program is underway,

RCS AF-XDD-A2

1. susuany
The first flight test of the Air Force Air Reconnaissance System (ARS)

vehicle will be conducted from Cooke Air Force Base, California in late 1958
with a THOR-boosted ARS vehicle.

The first flight test of an ATLAS-boosted ARS vehicle is scheduled for
mid-1959 from the Air Force Missile Test Center (AFNIC), Florida. ‘The first
ATLAS-boosted flight from Cooke Air Force Base is tentatively scheduled for
March 1960,

A captive test ARS vehicle, for use in the ATLAS-booster test program,
is scheduled for completion in February 1959. It will undergo testing at
the Lockheed Missile Systems Division test base at Santa Crus, California.
The test facility was completed during April.

A functional mockup of the airframe of the ARS vehicle is nearing
completion at Lockheed Aircraft Corporation.

The Eagle Picher Company has been awarded a contract for. supplying
non-chargeable storage batteries for use with ARS THOR-boosted guided
flights.

The Hoffman Company has been awarded e contract for development,
fabrication, and testing of prototype photovoltaic solar arrays. The arrays
will use solar energy to charge the storage batteries of the vehicle.

A light-weight, all-inertial guidance subsystem is being developed by
the Massachusetts Institute of Technology. Present plans call for the first
flight of the subsystem in early 1961. ‘

Successful measurements of infrared radiation from an intercontinental
ballistic missile were made during the flight of ATLAS missile 15A. The
measurements were taken to determine how an ICBM appears to a satellite-
borne infrared scanner during the power and altitude stages of the missile
trajectory.

‘

Five tracking and acquisition stations for data collection from ARS
launchings will be required. These stations probably will be located in the
vicinities of Cooke Air Force Base; Oxnard, California; Kaena Point, Hawaii;
Anchorage, Alaska; and Sitka, Alaska.

Design modifications to launch complex 75-3 at Cooke Air Force Base
are completed. This complex will be used for launching THOR-boogted vehicles.
Siting and design of a launch complex for ARS ATLAS-boosted vehicles at AFMTC
are in progress. Design criteria have been established for modifications of
the ATLAS launch complex #14 service tower.

1. All aspects of the guidance and control subsystem for the
THOR-boosted SENTRY Program are on schedule. Figure 5 depicts a typical
launch-to-orbit of the SENTRY vehicle. Figure 6 outlines the typical
Stound trace of the satellite when launched on an 183 degree orbit. e

2. All components of the guidance and flight control sub-
system for SENTRY/THOR #1, and a number of components for SENTRY/THOR #2,
were received by Lockheed and ‘subjected to acceptance and checkout testing.
An attitude desping unit for controlling the satellite in orbit will be
used for the first time on SENTRY/THOR #2.

' Deliveries of major items of equipment for the communications
subsystem are on schedule. Equipment is being delivered to telemetry sites
and tracking and acquisition stations. Shakedown teste of the downrange
telemetry ship to be used in the launch program at Vandenberg Air Force
Base are scheduled for October, A 60-word-per-minute teletype communica-
tions check of the ground Communications system is also scheduled for
October.

1. All components of the guidance and flight control subsystem
for SENTRY flight vehicle #1 heve been received by Lockheed and are under-
going acceptance and checkout tests. No major discrepancies have been found.

2. A number of components for SENTRY flight vehicle #2 have
also been received and are undergoing tests. Among these is an attitude
damping unit which will be used to Control the satellite attitude in orbit.
Attitude damping will not be used on flight vehicle #1.

developer solution on the web material. The web is brought into contact

with the exposed film and Processing takes place while the two are in contact.
The processor. does not require solution Storage tanks, valves, or Plumbing
and gives promise of being a highly reliable item. During the 24-day
unattended test, photographic quality was maintained at an acceptable level.

2. The first model of the high-speed 35 om processor for the
ground station has been delivered and is being readied for testing.
A development model of the film readout equipment built by the Columbia
Broadcasting System for Eastman Kodak is undergoing tests at the Rastman
Kodak Company. Initial tests of these equipments have deen successful;
however, considerable equipment “deb: "is necessary. A simulated
air photo mosaic of the SENTRY visual reconnaissance system using a six-
inch focal length lens is shown in Figure 10.

F, BIOMEDICAL SUBSYSTEM

1. Detailed plans have been established for recovery of the (eee
biomedical capsule. The recovery phase will operate in the fol:

manner. On the seventeenth Pass over Alaska, a ground signal to the
satellite programmer will command the satellite (orbiting in a horizontal
nose-first attitude) to pitch dow on the eighteenth pass. The biomedical
recovery capsule is then separated from the SEWTRY satellite. A set: of

two spin rockets is fired and the biomedical recovery Package is spun at
approximately 60 rpm for stabilization. The retro-rocket is then fired.
After the retro-rocket is fired, a set of two additional spin rockets is
