1.0 INTRODUCTION

1.1 Background

Since 1979 Essex has been Involved in the development of the Hubble

Space Telescope (HST) mockup and the performance of underwater

simulations to evaluate proposed on-orbit servicing tasks. These tasks

involve the planned changeout of scientific instruments and the

unscheduled changeout of other orbital replacement units (ORUs) such as

batteries and computers. The HST components and subsystems that

originally were designated ORUs were the items that were mission

critical and were designed for easy changeout. Other items located in

the Optical Telescope Assembly Equipment Section (OTA/ES) and the

Support Systems Module Equipment Section (SSM/ES) were later considered

for on-orbit changeout since the items were accessible to the

Extravehicular Activity (EVA) crew members and many items had EVAcompatible electrical connectors and mechanical fasteners.

In meetings held in October and November, 1984 between MSFC and

Essex personnel, the initial test objectives and mockup design

requirements were established in preliminary form. At these meetings

the following ground rules were established:

1. The primary objective of the test would be to evaluate crew

access to the potential ORUs and their electrical connectors and

mechanical fasteners.

2. ORUs would be mounted to a bolt plate that would be mounted to

the equipment section structure. This would allow removal of an ORU for

modification or repair without removal of the entire equipment section.

3. Substitution of "like items" would be acceptable for long lead

time components such as electrical connectors.

4. Pins would not be supplied for the electrical connectors.

5. Lockheed would supply any OTA/ES and SSM/ES drawings and

photographs needed to develop the mockup.

In December, 1984, Essex was awarded a contract to design and

fabricate mockups of 14 non-ORU items for the purpose of evaluating the

EVA changeout tasks in the MSFC Neutral Buoyancy Simulator (NBS). The

contract was later modified to include three additional non-ORUs.
1.2 Scope

High fidelity mockups of HST hardware not previously designated as

ORUs were necessary for changeout studies conducted in the MSFC NBS.

These mockups were developed by Essex and were identical to the flight

hardware in terms of location and method of attachment to the

spacecraft. The mockups had cable connectors identical to the flight

hardware where possible. The mockups provided by Essex include:

o Data Management Unit (DMU)

o Multiple Access Transponder (MAT) (2 required)

o Solar Array Drive Electronics (SADE) (2 required)

o Tape Recorder (3 required)

o Data Interface Unit (DIU) (2 required)

o Power Distribution Unit (PDU) (2 required)

o Deployment Control Electronics (DCE)

o Electrical Power/Thermal Conditioning Electronics (EP/TCE)

o Optical Control Electronics (OCE)

o Single Access Transmitter (SAT)

o Mechanism Control Unit (MCU).

The objectives of this design/fabrication/test activity were to

design and fabricate the potential ORUs so they contained realistic

interfaces and were compatible with the NBS environment. The attachment

of the mockup hardware to the spacecraft mockup was similar to the

flight version. Also, the hardware connectors were flight-like. The

cabling from the spacecraft bays to the hardware was developed to

closely simulate the flight hardware. The hardware produced includes:

o DMU - This unit is located on the Bay 1 door and is attached by

22 fasteners. It has 38 connectors with accompanying cabling.

o MAT - This unit is located on the Bay 5 door and is attached by

18 fasteners. It has 15 cables and interfacing connectors.

Two MAT mockups were provided.

o SADE - These two units are attached to the Bay 7 door by a total

of 12 fasteners. There are 10 connectors and cables per unit.

o Tape Recorder - There are two tape recorders mounted in the back

of Bay 5. The tape recorders are held in place by four fasteners

(eight total). The tape recorders have three connectors and

cables each. A third tape recorder was built for changeout

purposes.

o DIU - The DIU is installed with six fasteners in the back of

Bay 7. The DIU has 20 connectors and cables interfacing with it.

Two DIUs were provided.

o PDU - There are four PDUs. Two are high-fidelity and two

are low-fidelity. The PDUs are held in place by 10 fasteners

each and have 14 connectors and cables connected to each of them.
o DCE - The DCE is located on the door of Bay 7. It is held in

place by six fasteners. It has 14 cables and connectors attached

to it.

o EP/TCE - The EP/TCE is located in the rear of Bay H in the OTA

Equipment Section. It contains four fastening screws and 28

connectors/cables.

o OCE - The OCE is located on the Bay C door and is attached with

four bolts. The OCE has 13 connectors and cables.

o SAT - The SAT is located on the Bay 5 door and has five

connectors and eight bolts.

o MCU - The MCU is located inside Bay 7 above the DIU, and is

attached with four bolts. It has six connectors and cables.

2.0 TECHNICAL APPROACH

The following paragraphs describe the tasks performed for the

design and fabrication of the non-ORUs and the test support activity.

2.1 Task 1 - Review Space Telescope Drawings

Essex reviewed the NASA-provided drawings of the non-ORUs and their

mountings. Flight-type fidelity was provided in areas of critical crew

interface such as ORU connectors, spacecraft mountings, and module

attach point interfaces. All electrical connectors were identified and

ordered. Where the desired connector could not be obtained, connectors

were used that most closely approximated the correct external

dimensions. The connectors were pinless to reduce costs.

2.2 Task 2 - Prepare Mockup Drawings

Based on the information obtained in Task 1, engineering drawings

were prepared or in some cases, flight drawings were redlined. The

drawings incorporated high-fidelity areas of crew interface and

low-fidelity design in other areas. Upon completion, these drawings

were reviewed with the COR for approval.

2.3 Task 3 - Fabricate Hardware

Fabrication began immediately after COR approval of the drawings.

As the items were completed, the finished products were checked by the

project manager to verify proper dimensions and configuration.

2.4 Task 4 - Delivery and Installation and Support Tests

Essex then installed the non-ORUs into the Equipment Sections and

delivered the completed mockup to the NBS. Essex divers assisted the

NBS personnel in hardware installation and hardware support during the

test activity.
3.0 HARDWARE DESCRIPTION

The non-ORU mockups were all constructed with 6061-T6 aluminum and

stainless steel fasteners per redlined flight drawings or mockup

drawings prepared by Essex. Crew-operated mechanical fasteners were

identical to the flight configuration and fabricated with 300 series

corrosion resistant steel. Electrical connectors were purchased with

the same clocking and keying characteristics as the flight connectors,

and cables were similar to the flight cables in number of wires and size

of wire bundle. Descriptions of the individual non-ORUs are included in

Paragraph 1.2. Appendix A lists the connectors used on each non-ORU.

Appendix B includes photographs of the mockup hardware. Appendix C

lists sources of information for each non-ORU.

4.0 PROBLEM AREAS

Two problems occurred during the performance of the design/

fabrication tasks that were unforeseen at the beginning of the project

and affected the delivery schedule. These problems are briefly

described below.

4.1 Drawing Accuracy and Availability

In November 1984, Essex requested drawings and photographs from

Lockheed for each non-ORU since the drawings were not available at MSFC.

When received, some ORU drawings were not detailed enough to start

mockup fabrication. Key dimensions were missing and the drawings and

photographs did not always agree. Additional drawings were requested on

two later dates. When the drawing and photograph files were complete,

it was noted that the Lockheed and vendor drawings did not agree in all

areas. In the case of the Multiple Access Transponder (MAT), the

dimensional differences between Lockheed and Motorola drawings were

minor (< .2 in.) but were significant enough to cause fastener access

problems and tool/fastener misalignment (Reference Lockheed drawing

4171844 and Motorola drawing 70-P07705L, Appendix D). If an "as built"

drawing file is prepared to support maintenance and repair of the HST,

care should be taken to acquire not only Lockheed's drawings but the

drawings of the subcontractors and vendors as well.

No inconsistencies or other problems were encountered with the

Perkin-Elmer drawings used.

4.2 Mockup Fidelity

The non-ORU mockups were originally to be used to evaluate crew

access. After the contract was underway, it was determined that the

tests would include evaluations of connector tools and would require

high fidelity connectors and cable bundles. Although this did not

impact cost, the lead time for information and supplier delivery for

some of the connectors delayed hardware delivery in some cases.
Essex is not confident that the MAT, SAT, and DCE mockups reflect

the as-built configuration due to accuracy of information supplied to

Essex designers and potential modifications to the flight units that may

have occurred after the drawings were prepared. Also, Essex is unsure

of the fidelity of the coax connectors on the DMU. In these cases, the

mockups were fabricated to meet NBS test schedules and Essex had to rely

on the drawings that were available at the time.
