ABB drive system to power Boeing wind tunnel

ABB驅動系統為波音公司風洞提供動力系統

An ABB variable speed drive system is to power the giant fan that generates subsonic wind speeds at Boeing’s flagship wind tunnel in Philadelphia. ABB has supplied similar drive systems for wind tunnels operated by NASA and the U.S. Air Force.

ABB的一個變速驅動系統正在為波音公司在費城的旗艦風洞的大型風扇提供動力，以制造出次音速風速。ABB還為美國國家航空和宇宙航行局（NASA）以及美國空軍的風洞提供了類似的驅動系統。

Boeing has selected an ABB ACS 5000 variable speed drive system for its Vertical/Short Takeoff and Landing Wind Tunnel (BVWT V/STOL) in Philadelphia in the United States.

波音為其位于美國費城的垂直/短道起飛和降落風洞(BVWT V/STOL)選擇了ABB的ACS 5000變速驅動系統。

The 14 megawatt (MW) ACS 5000 drive and 18,800 horsepower (hp) synchronous motor will power the giant fan and fan blades that create wind speeds of up to 235 knots (435 kilometers per hour) for testing sophisticated aircraft models in the wind tunnel. Hundreds of pressure sensors are embedded in the models to measure aerodynamic performance during takeoff and landing.

14兆瓦特的ACS 5000驅動和18,800馬力的同步電機將為這大型風扇及其扇片提供可以產生高達235哩/小時（435公里/小時）的風速的動力，以測試在風洞里各種復雜飛機模型的情況。數以百計的壓力傳感器嵌入到這些模型里，測量起飛和降落期間的空氣動力性能。

The ACS 5000 variable speed drive system enables Boeing to run the fan in adjustable speed mode or at constant speed, depending on the protocols and parameters of each test.

ACS 5000變速驅動系統使得波音公司可以根據每個測試的規程和參數，自由設定可調速度模式或者恒速模式。

The drive system replaces a vintage ABB variable speed drive system from 1968, and is part of an overall upgrade of the wind tunnel to turn it into one of the best test facilities in the world for obtaining aerodynamic performance data.

該變速系統替換了ABB在1968年安裝的較落后的原有變速系統，而且是該風洞全面升級的一部分，全面升級之后它將成為世界上獲得空氣動力性能數據最好的測試風洞之一。

ABB has previously supplied drive systems for wind tunnels operated by the National Aeronautics and Space Administration (NASA) and the U.S. Air Force. The 101 MW drive and 135,000 hp synchronous motor at NASA’s National Transonic Facility in Virginia is the biggest and most powerful variable speed drive system in the world. It enables NASA to create the operating conditions for large transport aircraft flying at transonic speeds of up to 1,440 kilometers per hour.

ABB曾經為美國國家航空和宇宙航行局（NASA）以及美國空軍的風洞提供過驅動系統。NASA位于維吉尼亞州的國家跨音速實驗室的101兆瓦驅動和135,000馬力同步電機是世界上最大和最強大的變速驅動系統。它使得NASA可以為大型運輸航天飛機創造出運行條件，以每小時1,440公里的跨音速飛行。

Impressed by the power and capability of the NASA installation, the U.S. Air Force selected ABB to supply two 69,000 hp variable speed drive systems for its Propulsion Wind Tunnel facility in Tennessee, as well as two 30 MW softstarters to start up a total of 18 synchronous motors ranging from 27,000 - 52,000 hp at the USAF Aeropropulsion System Test Facility, also in Tennessee.

受到NASA安裝系統的功率和容量的影響，美國空軍也選擇了ABB為其位于田納西州的推進風洞實驗室提供了兩套69,000馬力變速驅動系統，以及兩個30兆瓦的軟起動器，起動其同樣位于田納西州的美國空軍飛行推進力系統測試實驗室共18臺功率從27,000到52,000馬力的同步電機。

ABB is the world's leading supplier of variable speed drives.

ABB是全球領先的變速驅動供應商。
