VI. CONCLUSIONS

I. EXECUTIVE SUMMARY

The Age Sensitivity Item Analysis (ASIA) on the Guided Missile Flight Controller (GMFC) has concluded that the component is age sensitive and that it should be included in the ALCM A&S program. This report documents the analytical approach, laboratory findings, and rationale leading to the recommendation for proceeding with the development of an Environmental Test Plan (ETP) and Test Requirements Document (TRD).

Aside from various manufacturing defects and process optimization issues discovered during laboratory analysis, many components used in the GMFC have aging effects and conditions that alone, or in combination, could eventually cause the unit to fail. The aging effects include:

Metal migration leading to high leakage currents, increased equivalent series resistance, and/or open/short circuits in wet tantalum capacitors, polycarbonate capacitors, ceramic capacitors, RF filter capacitors, EMI filter capacitors, Zener diodes, and ICs.

Corrosion due to contamination, Fractured seals in wet tantalum capacitors, paper/plastic capacitors, RF filter capacitors, diodes, ICs, discrete wires, and connectors.

Thermal decomposition, stress, and/or fatigue leading to loss of continuity or leakage, open circuits, or change in characteristic values in wet and solid tantalum capacitors, ceramic capacitors, RF filter capacitors, transistors, inductors, transformers, relays and ICs.

Moisture ingress due to voids or delaminations in conformal coating or damaged interface seals at electrical connectors could lead to long term performance issues.

Embrittlement and cracking of the EMI seal could limit weapon system effectiveness under specified environmental conditions.

The GMFC is expected to provide functional capabilities for the ALCM thru FY30. Having become operational in 1982, the component has delivered over 30 years of useful service and exceeded the weapon system component design goals of 10 to 15 years. It is obvious that the workmanship, materials selected, and production technologies utilized resulted in delivery of hardware of sufficient quality to meet the original design life. Continued assessment of the parameters defined will allow for service life extensions with confidence while providing the means of detecting unacceptable levels of degradation.

II. PHYSICAL DESCRIPTION

The Guided Missile Flight Controller (GMFC) is defined on drawing 232-11270-

21. The source for all GMFCs was The Boeing Company, CAGE 81205, more commonly referred to as Boeing.

1. The GMFC weighs 17.3 pounds and has physical dimensions that encompass approximately 8.7 inches in depth, 12.0 inches in width and 7.9 inches in height.

2. Power requirements for the device include +28 Vdc and 115 Vac, 400 Hz input power. The GMFC provides +/- 15 Vdc output control power to both the Flight Data Transmitter and Elevon Actuator Controller. The GMFC transforms the 115 Vac, 400 Hz input signal to a 10 Vrms, 400 Hz signal for output to the Inertial Navigation System and 8 Vrms, at both 400 Hz and 3908 Hz for output to the Flight Data Transmitter.

3. The GMFC includes eight electronic assemblies which are mounted in the cast aluminum housing. Connections within the flight controller are made by means of a wiring harness and circuit-card connectors. Top and bottom screw-mounted covers provide internal access to the unit. Electrical interface with other units of the air vehicle is provided by two multiple-pin connectors.

A third multiple-pin connector provides test interface capability.

Electromagnetic shielding is provided by EMI gaskets on top and bottom covers and all connector mounting cutouts. The eight electronic assemblies within the GMFC are identified in Table1.

Power distribution within the GMFC is a function of the EMI Filter. All input power and return lines are routed to J1 of the GMFC which is an integral component of the EMI Filter. Figure 3 shows a top level depiction of the power distribution for the GMFC.

Figure 3: GMFC Power Distribution

The GMFC internal wiring consists of a single bundle that includes all signal lines to all interface connectors, both internal (P1 to the EMI Filter and the 10 interface connectors for the A1-A9 CCA modules) and external (J2 and J3), as well as to chassis ground where necessary. All signal paths within the GMFC are point to point. That is, each pin from Jacks J2 and J3 has an individual multi-strand conductor to the destination point.

Further, each pin from the EMI Filter connector J2 and all internal CCA mating connectors on the card cage have single multi-strand conductors to their destination points. There are 3 separate junctions, E1, E2, and E3, in the wiring harness where the 28 VDC Switched, 28 VDC Un-switched, and 28 VDC Return lines from the EMI Filter have been spliced to accommodate multiple signal paths. A top level depiction of the GMFC internal electrical interface is shown in Figure 4.

subsequently provides analog outputs to the engine throttle control and elevon actuator controller. In this manner, the GMFC controls both the speed of the missile and the pitch and roll, or flight attitude. Two power supply assemblies in the GMFC provide self serving operating voltages as well as operating voltages to both the flight data transmitter and the elevon actuator controller. In addition to the flight control circuitry, the GMFC contains circuits that provide built-in–test equipment (BITE) capabilities for the missile. This BITE test capability augments ground test operations as well as pre-launch testing to check and verify operation of the flight control functions.

IV. AGING STUDY

4-1 Description of Components

The GMFC includes a top and a bottom cover that allow access to the internal assemblies for overhaul and maintenance activities. Figure 3 shows the overall assembly, while Figure 4 shows assembly views with the covers removed from the housing.

Figure 3 GMFC Assembly

Figure 4 GMFC Views with Top and Bottom Covers Removed

The bottom cover provides access for installation and removal actions for the Circuit Card Assemblies (CCAs A2 thru A9), as well as the EMI Filter (A1) while the top cover provides access to the wiring harness and harness interface connectors that provide signal paths from the individual CCAs to other CCAs, the Filter Assembly and the external output connectors of the GMFC.

4.1.1 EMI Filter Assembly (A1, 232-11678-4)

The EMI Filter houses GMFC assembly interface connector J1 which is a 7-pin Military Standard (MS27508) surface mount connector. Four pins in the connector are used to provide 115 VAC, 400 Hz and 28 VDC input power and return lines. Internal EMI Filter circuitry provides power signal routing, conditioning, filtering and control to distribute power to the Circuit Card Assemblies (CCAs) within the GMFC. Power distributed to the GMFC internal circuitry is provided through Relay Assembly connector J2 (P/N M24308/2-1 per MIL-DTL-24308/2T), which is a miniature rectangular connector with crimp style socket contacts. The EMI Filter is a 2 stage device, in that the input power through J1 is conditioned via 2 independent inductors in a physically isolated chamber and then fed to secondary chamber via two feed thru capacitors for the 115VAC power and two filters for the 28VDC power. The secondary chamber contains all additional signal conditioning and control functions. A single layer circuit board in the secondary chamber contains 9 capacitors, 2 inductors, a resistor, a diode and a relay which are configured for all necessary conditioning and control functions for the EMI Filter. Figure 5 includes photos of an EMI Filter with the rear cover removed.

Figure 5 EMI Filter (A1) with Rear Cover Removed

4.1.2 DC Power Supply (A2, 232-11677-5)

The DC Power Supply includes 2 circuit card assemblies (CCAs) that are mounted together in a clam shell configuration using 5 stand-offs and mounting screws. The 2 CCAs are electronically linked via an interface jumper that consists of a set of 10 wires. The engineering data refers to the larger circuit board as A2A1 and the smaller circuit board as A2A2. Circuit Card A2A1 contains the interface connector that mates the DC Power Supply to the GMFC interface harness. In addition, CCA A2A1 houses 6 inductors, 2 transformers, 9 diodes, 17 capacitors, and 11 resistors on its printed wiring board. Circuit Card A2A2 contains 6 inductors, 2 transformers, 10 diodes, 13 transistors, 20 capacitors, 43 resistors, and 4 ICs on its printed wiring board.

In general, CCA A2A1 provides the signal paths, transformers and rectifier circuits necessary to convert the un-switched 28 Volt input signal to the conditioned +5, +15 and -15 VDC power and return paths for CCAs A3 thru A9.

Similarly, CCA A2A2 provides control and monitor functions for the output signals.

Figure 6 shows the DC Power Supply in a partially disassembled state with all mounted components showing.

4.1.3 BITE Circuit Card Assembly (A4, 232-11668-4)

The BITE CCA, A4, provides a built-in-test equipment feature to augment ground test operations as well as pre-launch testing to check and verify operation of the flight control functions. The CCAs circuit board houses 16 ICs, 5 diodes, 30 capacitors, 5 transistors, 72 resistors and 2 up-screened 2-pole double-throw relays.

Figure 7 shows the top surface of the BITE CCA with all mounted component parts showing.

Figure 7 BITE CCA (A4) Top View

4.1.4 Roll Circuit Card Assembly (A5, 232-11670-5)

The Roll CCA, A5, provides control circuitry to take inputs from the Inertial Navigation Element and other GMFC resources to provide roll control functions for the missile. The Roll CCA circuit board houses 11 ICs, 40 capacitors, 1 transistor, 60 resistors, 3 diodes, and 1 up-screened 2-pole double-throw relay.

One subset of the CCA ICs, include 4 unique ICs that are hybrid microcircuits composed of 6 individual chips and 22 transistors.

Figure 8 shows the top surface of the Roll CCA with all mounted component parts showing.

Figure 8 Roll CCA (A5) Top View

4.1.5 Pitch Circuit Card Assembly (A6, 232-11671-5)

The Pitch CCA, A6, provides control circuitry to take inputs from the Inertial Navigation Element and other GMFC resources to establish pitch control functions for the missile. The Pitch CCA circuit board houses 10 ICs, 49 capacitors, 2 transistors, 54 resistors, 4 diodes, and 1 up-screened 2-pole double-throw relay. One subset of the CCA ICs, include 2 unique ICs that are hybrid microcircuits composed of 6 individual chips and 22 transistors.

Figure 9 shows the top surface of the Pitch CCA with all mounted component

Figure 9 Pitch CCA (A6) Top View

4.1.6 Command Circuit Card Assembly (A7, 232-11669-7)

The Command CCA, A7, provides command and control for various mission functions to include throttle control and directional control inputs. The Command CCA circuit board houses 19 ICs, 28 capacitors, 6 transistors, 44 resistors, 14 diodes, and 2 up-screened 2-pole double-throw relays. One subset of the CCA ICs, include 2 unique ICs that are hybrid microcircuits composed of 6 individual chips and 22 transistors. (Note: During disassembly of GMFC S/N 945, the A7 capacitor C271 was not populated. The A7 CCA showed it was a 232-11669-5 while the CCA from 1292 is a -6 and it is populated. Multiple CCA versions may require future statistical analysis efforts to consider multiple lots in the regression analysis.)

Figure 10 shows the top surface of the Command CCA with all mounted component parts showing.

Figure 10 Command CCA (A7) Top View

4.1.7 Gyro Interface Circuit Card Assembly (A8, 232-11667-4)

The Gyro Interface CCA, A8, provides error corrections for the pitch rate, roll rate and yaw rate based on gyro outputs. The Gyro Interface CCA circuit board houses 31 ICs, 34 capacitors, 6 transistors, 76 resistors, 1 diode, and 1 4-pole double-throw relay.

Figure 11 shows the top surface of the Gyro CCA with all mounted component

Figure 11 Gyro CCA (A8) Top View

4.1.8 AC Power Supply (A9, 232-11676-5)

The AC Power Supply CCA, A9, includes 2 circuit card assemblies (CCAs) that are mounted together in a clam shell configuration using 6 stand-offs and mounting screws. The 2 CCAs are electronically linked via an interface jumper that consists of a set of 12 wires. The engineering data refers to the power supply as a device that includes the 2 circuit boards, 5 transistors, a transformer and the interface jumper. The larger circuit board contains the interface connector that mates the AC Power Supply to the GMFC interface harness. In addition, the larger board houses 1 inductor, 3 transformers, 1 IC, 10 diodes, 46 capacitors, 9 transistors, and 53 resistors on its printed wiring board. The smaller circuit board contains 12 ICs, 3 diodes, 2 transistors, 48 capacitors, and 48 resistors on its printed wiring board.

In general, the smaller circuit board provides gain control and low pass filtering functions for the larger board. The larger circuit board provides the power for the pitch, roll and yaw ground layer wavefront sensors (GWS) as well as the sensor pickoff and resolver excitation loads.

Figure 12 shows the AC Power Supply in a partially disassembled state with all mounted components showing.

4-2 Analysis Approach

The analysis approach used for the GMFC is illustrated in the following block diagram. Each step of the aging analysis is described in section 4.3.

4-3 Aging Analysis

This section describes the technical approach used to identify possible aging mechanisms for the GMFC.

4.3.1 Documentation Review

The effort began by gathering and reviewing the available manufacturing documentation for the GMFC. This consisted of the following items where available:

Production assembly and sub-assembly drawings Production piece-part fabrication drawings Military specifications referenced on the drawings Level III Test Requirements Documents ALCM Configuration Status Accounting System (ACSAS) database print-out of GMFC production and disposition information, by serial number * Reliability and Maintainability Information System (REMIS) print-out of

* Note: As of the time of this writing, current information from the REMIS and ACSAS data bases had not been received for review. That information will be used to update this document if it should become available and deemed sufficient to require an update.

In addition, the “Stockpile to Target Sequence” document for the ALCM was reviewed in order to gather data regarding the design environments to which the ALCM would be exposed after manufacture. The following table notes general information of interest for the purpose of the GMFC ASIA, which is a small portion of the data available in the document. This is not the exposure environment for the GMFC, since it is protected inside the ALCM, but it is a reference for worst-case conditions. Further, the GMFC is mounted among the other electronic assemblies of the weapon system in a compartment that is sealed and has desiccant to control humidity.

(Note: This document review was completed circa 1998 and the data should be verified based on any updates to the document that may have occurred in the interim. Should any variances exist between the data presented here and the latest documentation, an update to this report can be issued.)

The environmental information was augmented by discussions with field personnel at a main operating base, which was pursued in order to gain further insight into how the ALCMs are handled, how often they are handled, how often they are powered, etc. Following is a summary of the more relevant information:

ALCMs are handled a minimum of 2 times per year. Typical reasons for handling the ALCM’s include the following:

Practice loading ALCMs and pylons on an aircraft (no flight time, 1-2 times per year) Scheduled maintenance and test Upgrades and modifications

During any of the above, an electrical problem may be detected, or there may be body repairs required (the shop chief estimated about 30% of each group that was handled). This may require that the ALCM go through various shop repair procedures, which may include a Level I test

Each ALCM has seen electrical power (Level I testing) many times during their current life and for various reasons:

Initial acceptance Re-basing, with testing after ground shipment Test after engine change Test after electrical failure during interface checks Scheduled Analytical Condition Inspection/Service STAR testing at the depot (12 ALCMs per year) ALCMs are moved between the igloos, planes, and shops regardless of the weather (with the exception of lighting threats). This means that the ALCMs will see temperatures during the winter of –30 to –40 degrees Fahrenheit, with the absolute lowest temperature ever at the site being –68 degrees Fahrenheit.

Each ALCM has seen many cycles of rapid temperature change due to handling, as well as the normal seasonal temperature changes.

The ALCMs will get wet due to rain (outside exposure) and surface condensation (in the igloos). The interior of the ALCMs (in the electronics areas) are protected with desiccants; therefore, it can be assumed that humidity is generally not an environmental factor inside the ALCM.

However, it was noted that ALCMs may be stored in an unheated building, without the warhead, with the access cover removed.

The information gathered from the initial review of the documents was used in planning procedures for disassembly of GMFC samples, and for “brainstorming” of possible aging mechanisms.
