18、est article development as a way to recommend improvements in wind tunnel test efficiency, cost, and cycle time. Early on, it became apparent to the participants of the AIAA working group that trying to separate test article development from overall wind tunnel test process was not a productive and

19、useful activity. The highly integrated nature of the processes, organizations, and personnel involved in wind tunnel test projects require that a broader viewpoint of the wind tunnel test process be evaluated in order to develop successful techniques and methods. The two-part effort, “Recommended Pr

20、actices for Wind Tunnel Testing,” is the result of that evaluation. Part I was written to provide managers with clear insight into achieving technically focused, cost-efficient, low-risk test programs (which contain multiple test projects) that support the development of aerodynamic vehicles and tec

21、hnologies. This recommended-practices document will help managers understand the impact of decision making before and during the development of a test program and will provide key activities to help improve quality, timeliness, and cost-effectiveness of wind tunnel test projects. Part II provides ad

22、ditional detail on successful methods for those directly involved in developing and executing individual tests. Neither volume is intended to be a totally comprehensive document on successful wind tunnel testing. Instead, they represent a compilation of best practices to provide a strong foundation

23、for the successful development of a test program or test effort. While these practices focus on wind tunnel test processes, the information is applicable to many other ground test activities.

AIAA R-092-2-2003 1 Introduction The purpose of this recommended practice document is to provide the reader with increased knowledge about pla

32、nning and executing highly successful wind tunnel tests. First, an overview of the test process is provided, giving a general picture of the origin, purpose, and high-level breakdown of activities that are a part of wind tunnel test development and execution. Secondly, detail is added to the overvie

33、w to define the full scope of the activities and key considerations. Finally, recommended practices and lessons learned are described. Part I of this recommended practice looked at test development from a management perspective. This volume (Part Il) will provide additional detail that is more usefu

34、l to participants who develop and execute testing activities. Part II is organized into sections describing activities and best practices during the various stages of test implementation: Program development Pretest planning and preparation Model development and fabrication Pretest buildup and prepa

35、ration Testing Post-test activities Part II of this recommended practice document was assembled with guidance from experts (both industry and government) who are responsible for all aspects of wind tunnel testing. Experts from airframe companies (military and commercial), as well as model makers and

36、 tunnel operators contributed best practices to help guide test personnel through the implementation and execution of a test project. 2 Aircraft Program Development Aircraft designs continually push the state-of-the-art in technology. Advances in materials, instrumentation, and onboard computing wil

37、l continue to allow the design of higher performance, lighter weight aircraft. Consequently, wind tunnel testing has become more sophisticated as demands for improved aircraft performance have increased. Relatively simple aerodynamic tests of early years have broadened to highly specialized testing.

38、 Advances in wind tunnel test facilities and techniques are also impacting testing projects by reducing cycle times and increasing the amount, quality, and versatility of the data collected. As test requirements flow from a programmatic level to the finer detail of individual tests, activities and i

39、ssues associated with the requirements are developed and refined to enable the completion of individual tests. It is often during this flow down that the success or failure of a test effort is determined. 2.1 Overview As used in this document, an aircraft development program refers to the process by

40、 which a new aircraft or major derivative is created-from initial concept to production. The test project is the portion of the development program when testing is conducted. For this document, the test project will focus on a wind tunnel testing activity. Therefore, each test project is an integrat

41、ed and important part of the entire vehicle development program. The phase of a development program has direct bearing on the level of technical requirements for the individual test project. Traditionally, aircraft or technology development programs generally follow three phases: 1 AIAA R-092-2-2003

42、 Low-Speed Force and Moment (High- Lift) Phase 1 is the concept development and risk reduction phase. Initial configuration concepts are evaluated against program goals. Vehicle configurations change quite frequently. Parametric models, with multiple configuration variables, are investigative in nat

43、ure and high-fidelity simulations are usually not required. The purpose at this phase of the program is to select an initial configuration that will meet developmental goals. Phase 2 is the development of the flight vehicle, often referred to as the Engineering and Manufacturing Development (EMD) or

44、 Full-Scale Development (FSD) phase. The scope and amount of wind tunnel testing increases dramatically as models are tested throughout the vehicle envelope and simulated flight conditions. Model configurations become more refined as the development phase progresses. Test and model-fidelity requirem

45、ents increase as aerodynamic, propulsion, and aeroelastic goals are met. Phase 3 is the validation phase or production phase. In this phase, the final configuration has or is very close to being frozen, and full-scale production is underway. High-fidelity models with very stringent tolerance require

46、ments are tested to validate aerodynamic, propulsion, and aeroelastic performance predictions. Testing is conducted throughout the proposed flight envelope and flight conditions of the aircraft.

47、es of tests and models used for commercial aircraft development are presented in Table 1 and for military aircraft in Table 2. This document is presented from the perspective of testing that supports aircraft development. Other types of flight vehicles, such as missiles, helicopters, rockets, space

48、re-entry vehicles, and V/STOL aircraft, have developed their own unique testing requirements.
