15、mprovements in wind tunnel test efficiency, cost, and cycle time. It became apparent early on that trying toseparate test article development from overall wind tunnel test process was not a productive and usefulactivity. The highly integrated nature of the processes, organizations, and personnel inv

16、olved in windtunnel test programs requires that a broader viewpoint of the wind tunnel test process be evaluated inorder to develop successful techniques and methods. This two-volume effort, “Recommended Practicefor Successful Wind Tunnel Testing,” is the result of that evaluation.Part I was written

17、 to provide test program managers with clear insight into achieving technically focused,affordable, and low-risk test programs to support the development of aerodynamic vehicles andtechnologies. This recommended-practices document will help managers understand the impact ofdecision making before and

18、 during the development of a test program and will provide key activities tohelp improve quality, timeliness, and cost-effectiveness of wind tunnel test programs.Part II provides additional detail about successful methods for personnel who are directly involved indeveloping and executing test progra

While these practices focus on wind tunnel tes

While the time and expense of wind tunnel testing is s

30、ignificant, it is an essential riskreduction tool before progressing air vehicles and technologies to the more expensive, technically riskyflight tests. Decisions made during the evolution and execution of wind tunnel test programs can have far-reaching performance, financial, and schedule implicati

31、ons throughout the life cycle of an air vehicle.Efforts are being made across all air vehicle development activities to reduce technical risk, cost, and cycletime. Since wind tunnel test programs are critical to those development activities, any successfulreductions in wind tunnel risk, cost, or cyc

32、le time can have significant positive impacts on the overall airvehicle program.To accomplish a successful program, managers of wind tunnel test programs must carefully balance thetesting needs (objectives), schedules, and cost of the test program. Activities such as developing testrequirements, tes

33、t articles, test preparation, testing, and analysis require significant resource investmentsand must be carefully managed to accomplish technical goals with minimum resource expenditure.This volume describes the broader aspects of test program development, implementation, andmanagement. It provides

34、managers with a set of tools (key activities) to help navigate and develop abalanced, successful test program.1.1 History and BackgroundWind tunnel testing has been critical to aircraft development since it was first performed by Frank H.Wenham in Great Britain in 1871. Beginning in 1901, the Wright

35、 Brothers utilized a tunnel of their owndesign to increase their understanding of aerodynamic lift and control, which helped them produce thefirst powered aircraft in 1903.In todays highly competitive commercial aviation world, small improvements in aerodynamic performancecan translate into range an

36、d payload gains and, therefore, sales. Wind tunnel testing to develop air vehicleconfigurations involves extensive aerodynamic testing. Loads, flutter, and propulsion interaction testingare also important aspects of test programs. Military air vehicle development may include additional focuson testi

37、ng of broad test envelopes, weapons carriage, and highly integrated propulsion effects.Wind tunnel testing has historically provided the primary ground test mechanism for establishing airvehicle performance prior to committing designs to flying hardware. With increasing emphasis on lower airvehicle

38、development costs and cycle time, people in the test community have been asked to producehigher quality test results, quicker and for less cost.The desire to reduce cycle time (and cost) seemingly necessitates reductions in allotted span time forwind tunnel model design, fabrication, test preparatio

39、n, testing, and test analysis. Unfortunately, thesepressures can negatively affect the quality and cost of test programs. Therefore, it has becomeincreasingly difficult for test service providers to perform test work in a manner that is consistent withschedule pressures (at a minimum cost) while pro

40、viding the quality necessary to ensure a totallysuccessful test program.The tradeoffs between cost, quality, quantity of data, and schedule response, along with the processesemployed during test program activities, are the key focus areas for todays wind tunnel test management.To provide managers wi

41、th the best tools available, it is important to first understand the tradeoffs andtechniques that will yield successful test programs. These techniques include: Understanding technical goals (therefore data needs) before embarking on a test program Getting the right people involved early to minimize

42、 risk and cost (including early selection of thetest facility and test facility personnel)AIAA R-092-1-20032 Managing model and data fidelity to minimize costs and schedules Using a systematic process to develop, plan, and manage test programs Integrating test changes with minimum impact.2 Managing

43、Todays Wind Tunnel Test Programs2.1 Planning Issues in Wind Tunnel Test ProgramsMany significant factors ultimately influence the success of a test program. In the commercial aviationmarket, time-to-market is critical, driving measures of success in the direction of reduced cycle time. Ofcourse, cos

44、t is always of special importance. When developing defense articles, technical issues may beof overriding concern. Despite the potential priority differences for every type of development program,careful attention to the planning issues discussed below will significantly enhance the probability ofsu

45、ccess.Communication is a cornerstone activity within any test program. Early involvement of test communitypersonnel will facilitate the best (and lowest risk) planning. Careful generation and flow down of overallobjectives help the test personnel understand and execute the best possible plan. It is

46、also critical thatmanagement be involved during the test activities to help keep objectives and activities aligned and toencourage the test participants.2.1.1 Test RequirementsTest objectives must be documented and approved before any test-related activities are initiated. Testrequirements must be c

47、learly defined at the beginning of a test program and should be a direct result oftest objectives. These requirements must contain information such as measurements and accuracyneeded, time allotted to conduct test program, resources available (budget, people), security, modelsuppliers, test faciliti

48、es, special contractual issues, etc.2.1.1.1 Integrated Test ProgramsThe project developmental test program should optimize the benefits of flight test, wind tunnel test, andmodeling and analysis (AnnexnobreakspaceA.1, Integration of Testing and Computational Fluid Dynamics).Wind tunnel test programs

49、 often encompass multiple test entries at many different facilities. Efficienciescan often be gained (both schedule and budget) through careful integration across an entire testprogram. Examples of integration include using a single model for both low- and high-speed testing, usingcommon model scales (and potentially, parts) for several model types, and using a single test article toacquire several types of data (e.g., force and pressures), etc. These economies are not without risk, sincetest schedules and goals frequently change, and conflicts can arise.
