1 T-38 Fuselage FEM – Phase X

1 DESCRIPTION OF SERVICES

The following Performance Work Statement (PWS) provides a description of the required contractor services in support of the T-38 Aircraft Structural Integrity Program (ASIP), T-38 System Program Office (SPO), Air Education and Training Command (AETC), and other commands.

This contractual effort is limited to Phase X of the Finite Element Model (FEM) program and the required engineering efforts are binding towards meeting the Phase X requirements. Additional follow-on efforts are merely mentioned to depict the SPO’s overall program scheme and to ensure current efforts are considered by the contractor to facilitate integration towards required follow-on efforts and options.

Phase X, in and of itself, is of value to the T-38 ASIP’s FEM program for the purpose of continual improvement of the overall T-38 sustainment efforts, regardless whatever future efforts are accomplished.

1.1 Scope

This PWS specifies the Phase X tasks towards sustaining and improving the T-38C (PMP-equipped) fuselage FEM (as developed in Phases I through IX of this program), and final presentation of the updated model to the Government. This tasking includes the associated program management, engineering, and technical support required for this program. It should be noted that the complete FEM program will use a multi-phased approach as follows: Phase I -preliminary FEM development (complete); Phase II - idealized FEM development (complete);

Phase III - FEM validation and final reporting; and Phases IV through IX – FEM sustainment and improvement. Additional phases (e.g., Phase XI) will be considered by the Government on a yearly basis, and will be discussed with the contractor before the conclusion of Phase X.

2 SERVICE SUMMARY

Table 1 describes the Service Summary (SS) for the tasks as outlined in this PWS. Most of the efforts as described in this PWS will be engineering services and program management related.

4 GENERAL INFORMATION

4.1 General Requirements

General requirements for the Aircraft Structural Integrity Program (ASIP) are given in Air Force Instruction 63-1001 and Air Force Policy Directive 63-10 (see Ref. 1 and 2, Attachment One).

In addition, ASIP is detailed in Mil-STD-1530C (see Ref. 5, Attachment One).

4.2 Technical Objectives and Goals

The T-38 fuselage has undergone significant structural modifications over the last 20 years to extend its life to 2020 and beyond. Some of these modifications include the steel dorsal

4 T-38 Fuselage FEM – Phase X longeron replacement, new bulkheads, and the inclusion of auxiliary air intakes. These modifications change the internal loads, mass distribution, and stresses in the T-38 fuselage, thereby raising concern as to the applicability of earlier stress analyses for use on the current configuration T-38. Further, these modifications have not been integrated into a unified analysis model to determine their effects on the overall strength and internal loads of the fuselage. To address these issues, an updated, comprehensive FEM is needed for maintaining the long-term health and reparability of the aircraft.

The purpose of Phase X of this program is to sustain and improve upon the FEM of the T-38 fuselage, empennage, and wing developed during Phases I through IX, then to make a final report of the work performed to the Government. The updated and integrated Phase X FEM will continue to improve the accuracy of the loads and stress analysis of the aircraft, also allowing for more accurate damage tolerance analyses (DTAs). Further, the FEM information can be used to evaluate the legacy T-38 stress reports, currently used for structural analyses.

4.3 Specific Requirements

4.3.1 Contractor Services

The contractor shall provide the appropriate engineering, program management, and technical services as required for this PWS. Limited travel will be required to meet the goals of this effort.

4.3.1.1 T-38 FEM Program - Phase X: As part of Phases I-IX, a number of contractor reports were written to define the Government plans and contractor’s progress for the various FEM efforts (see Ref. 24-33, Attachment One). Reports for Phase IX are in progress, and shall be completed by September 2013. As a logical follow-on of the efforts of the first eight phases, Phase X will follow the most updated T- 38 FEM program plan. Improvement and sustainment modeling activities will be accomplished, with the T-38 fuselage finite element and validation models refined to reflect the T-38C, PMP-equipped configuration aircraft. Areas of model improvement shall be as specified in Table 2.

In addition to validation against the full scale fuselage test, the model will be improved by validating against current FLDR data. All final deliverables are due 12 months ARO contract award (CDRLs A040, A039, A045, and A090, Attachment Two).

4.3.1.1.1 Data Compatibility: All contractor FEM/FEA work shall be fully compatible with

MSC PATRAN 2010, NASTRAN 2010, and a MSFT Windows based operating system (CDRL A090, Attachment Two).
