PbKFORMANCE WORK STATEMENT

1 DESCRIPTlON 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 VIII of the Finite Element Model (FEM) program and the required engineering efforts are binding towards meeting the Phase VllI 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 VIII, 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 Services Provided by Northrop Grumman Technical Services

1.1.1 Engineering analysis to support T-38 FEM program (see Section 1.2).

1.1.2 Conduct Phase VllI program kick-off meeting by 30 days ARO and present updated FEM plan

1.1.3 Provide quarterly technical status reports, and monthly cost, schedule, and performance reports (CDRLs A026 and A039, Attachment Two).

1.1.4 Provide "level of effort engineering" on-site and off-site support; this includes (but is not limited to) analysis in support ofT-38 FEM improvement requirements, with [mal completion by 30 September 2012 (CDRL A039 and A045, Attachment Two).

1.1.5 Provide final engineering reporting that documents the finite element modeling and analysis activities; provide updated [mite element model files; completion date of 30 September 2012 (CDRL A045, and A090, Attachment Two).

1.2 Scope

This PWS specifies the Phase VIII tasks towards sustaining and improving the T-38C (pMP-equipped) fuselage FEM (as developed in Phases [ through VII of this program), and [mal presentation of the updated model to the Govemment. 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 VII - FEM sustainment

3.2 Security and Access to Government Facilities and Equipment

3.2.1 Security Clearance

The efforts required for this task are UNCLASSIFIED and will not require Contractor personnel to obtain a security clearance. Contractor personnel shall abide by all Air Force rules, procedures, and standard of conduct. Contractors requiring access to Air Force Automated Information Systems (AIS) shall have background investigations and security awareness training completed prior to the start of contract performance. When the period of performance is complete and/or the contractor personnel leave work on this project, they will return all access cards and base identification badges within five days.

3.2.2 Access to Government Facilities

Access to Government facilities is limited. Therefore, the contractor shall coordinate the need, time, and personnel requiring access to Government facilities with the Government Program Manager (PM), at least one week prior to need. The Government PM or designated representative will coordinate between the contractor and base personnel as required.

3.2.3 Access to Government Equipment

The Government PM will assist the contractor in obtaining the necessary clearance for access to Government equipment, as the program dictates.

4 GENERALINFO~TION

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. I and 2, Attachment One).

In addition, ASIP is detailed in MiI-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 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 VII of this program is to sustain and improve upon the FEM of the T-38 fuselage, empennage, and wing developed during Phases I through VII, then to make a final

4 T-38 Fuselage FEM - Phase VIII Last Rev. Date: 20 Jun 11

Pc,{fORMANCE WORK STATEMENT report of the work performed to the Government. The updated and integrated Phase VIII 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). In addition, 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. I 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.

As a logical follow-on of the efforts of the first three phases (plus three subsequent phases), Phase VIII will follow the aforementioned NOR 04-100 program plan, as approved by the Government.

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 refinement shall include all fatigue critical locations and other adjacent structure as deemed necessary. Final government approval of all refinement locations required. 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 A026, A039, A045, and A090, Attachment Two).

4.3.1.1.1 Data Compatibility: All contractor FEM/FEA work shall be fully compatible and usable when loaded onto OO-ALC/GHMEJ's FEMIFEA assets. At the present time, 558 ACSGIENJ has PATRAN 2008 (Rl), NASTRAN 2008 (Rl), and a MSFT Windows based operating system (CDRL A090, Attachment Two).
