2、itted without license from IHS-,-,-MIL-STD-3024 iiFOREWORD 1. This standard is approved for use by all Departments and Agencies of the Department of Defense. 2. The Department of Defense (DoD) is committed to ensuring a strong systems engineering approach in acquisition programs. This standard cover

3、s the procedures to be used to ensure propulsion system integrity during the System Development and cost and schedule risks managed through a series of disciplined, time-phased tasks. This standard details programmatic tasks for the development, acquisition, and sustainment of propulsion systems to

4、ensure their integrity while affordability of these United States Air Force (USAF) systems is maintained throughout their period of use. 1.2 Application. This standard provides information to develop a Propulsion System Integrity Program. The standard applies to a particular propulsion program and a

5、ir vehicle system, as follows: 1.2.1 Type of air vehicle. This standard is directly applicable to air vehicles which have a propulsion system based on or powered by a gas turbine engine. 1.2.2 Type of propulsion system. This standard applies to gas turbine propulsion systems. The term “Propulsion Sy

6、stem” in this document refers to an engine and engine accessories. Inlets, nacelles, pylons, engine bay, and ventilation components are not intended to be included in this document. Exhaust nozzles are intended to be included in this document, even those designed and manufactured by an airframe manu

7、facturer. 1.2.3 Type of program. This standard is applicable to new propulsion systems, to propulsion systems procured by the USAF but developed under the auspices of other government agencies or departments (such as the Federal Aviation Administration or United States Navy), and propulsion systems

8、modified or directed to new missions. 1.2.3.1 Program impact on tailoring. It is expected this standard will be tailored to fit the needs of a given program. Specific tailoring guidance is given in 6.4. Procurement of off-the-shelf, new or used propulsion systems for military use presents different

9、challenges than procurement of propulsion systems developed under the auspices of the military services. The concepts and intent of this document will apply to these types of systems, but may require significant tailoring. 1.3 Functional scope. This document details the PSIP requirements for the fun

10、ctional areas of Structures, Performance and Operability, and Controls and Subsystems. As will be described in section 4, development of the PSIP Master Plan is a significant requirement to achieve system integrity. The Master Plan is expected to be comprehensive, and include activities needed to at

11、tain integrity in other functional areas, such as Manufacturing, Safety, Reliability and Maintainability, etc. Detailed PSIP requirements for these functional areas are not included in this document due to the availability of other government guides, handbooks, and standards. 1.4 Document layout. Th

12、is document follows the prescribed format for military standards, which reserves section 4 for General Requirements and section 5 for Detailed Requirements. Within this construct this document covers three functional areas with five PSIP task categories. To achieve this, it was decided all Task I re

13、quirements were universally applicable to the three functional areas and would be included in section 4, General Requirements. Section 5, Detailed Requirements, contains three primary subsections, each identifying the Task II V requirements for each functional area. Although it could be argued that

14、Task V applies to all functional areas, it was considered unique for each for the initial release of this document. Appendix A contains tables which list guidance for Task completion criteria for the various program milestones. This guidance is to be used to develop criteria to move to the next prog

15、ram milestone as described in 4.4.2.2. Microsoft Wordand Adobe Acrobatversions of this document contain hyperlinks which are identifiable by blue-font characters. Once selected, a hyperlink will take the user to a referenced paragraph, table, figure, and Website. The simplest way to return to the pl

16、ace of origin within a Microsoft Worddocument is to click the “back arrow” on the “Web” toolbar. This toolbar can be displayed by selecting “View” and “Toolbars” on the menu bar, and then selecting the “Web” option. This same method can be employed in Adobe Acrobatversions of a document: select Prov

34、tems). This expansion was accomplished by incorporating the relevant criteria from the highly-successful ASIP, AVIP, MECSIP, and ENSIP. 4.2 PSIP goals. The PSIP is an organized and disciplined engineering and management process to assure that the integrity of the engine is achieved in the developmen

35、t program and maintained throughout operational service. The PSIP process consists of phased tasks that increase knowledge of the true characteristics of the propulsion system being developed. The goal of the PSIP process is to use the knowledge gained from these tasks to balance cost and risk and m

36、aximize product maturity. The phased tasks will focus on the following: Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-3024 6a. Application of a disciplined “system engineering approach” to design and development with emphasis on determining

37、 and understanding failure processes and consequences on operational performance. b. Understanding the total system operational and support needs and the development of subsystem and component requirements and characteristics to assure that these needs are met. c. Emphasis on realistic integrity req

38、uirements, required operational service life, required performance/operability/functionality, understanding of usage and environments (including maintenance and support) as the basis for design and qualification. d. Early trade studies to evaluate operation and support factors together with cost, we

39、ight, and performance, and to ensure compatibility between design solutions and support equipment needs and maintenance concepts. e. A disciplined design and development process scheduled to assure early evaluation of component response to design usage, material characteristics, manufacturing proces

40、ses, and the establishment of operational limits (failure modes and service lives) in terms of design usage. f. An integrated analysis and ground test program to evaluate design performance and integrity characteristics and to verify requirements. g. Scheduling of tests and demonstrations to assure

41、that test findings are incorporated into design in advance of major economic and/or qualification initiation and production commitments. h. Quality assurance strategy with special emphasis on planning, supplier quality, control of manufacturing variability, failure investigation, and corrective acti

42、on to assure quality and integrity of hardware throughout production. i. Development of force management requirements (including maintenance and inspection requirements) based on the results of the development process. j. Follow-up control for the fielded engines through maintenance, inspection, and

43、 data gathering. k. Investigation of the need to track usage on components and subsystems in service. l. A program to accomplish force management. 4.3 General description of the primary PSIP tasks. The PSIP follows a five-task element approach. This approach has been derived from the systems enginee

44、ring process. The systems engineering process is shown on figure 1. Systems engineering begins with the definition of top-level system requirements, allocating those requirements to a lower level, designing hardware to meet the requirements, followed by verification that the requirements have been m

45、et. And, as the figure indicates, the process can be iterative. The five-task PSIP approach accomplishes the systems engineering process. As the tasks are accomplished, knowledge of the system characteristics increases. The PSIP represents a logical, methodical, technically-sound development strateg

46、y in which engineering assumptions are verified and component limits are accurately defined before parts are released to production. Potential failure mechanisms are identified, understood, and controlled. Increased emphasis is placed on performing early analyses and conducting incremental engineeri

47、ng development tests to verify analytical assumptions. The process also emphasizes that sufficient knowledge is gained on engine components in support of major program milestones and suggests that performance and durability tests that simulate realistic operating environments are one way to demonstr

48、ate that knowledge. A general description of the five integrity tasks is given in the following sections. Engineering judgment needs to be used to tailor these tasks to fit the needs of each unique program. Knowledge-based criteria should be the basis of any engineering judgment used to tailor the P

49、SIP, and should be clearly communicated in the initial PSIP Master Plan and any updates. New engine programs may need to do most, if not all, of the sub-tasks outlined here. Derivative programs may need only a smaller sub-set. The sub-tasks descriptions which follow are not intended to be all-inclusive, but rather to represent considerations for typical engine development. The major sub-tasks or elements contained in each of the five tasks
