美國新一代無人艦載匿蹤轟炸機

前一陣子大家還在討論中國大陸有關新一代的匿蹤戰機的消息,

結果:人家老美隨隨便便就又可以從口袋中掏出新玩意了。

當然以我們從科技發展的軌跡來看,一點也不覺得意外,

大家從以下那一部測試影片可以看出,人家也不是說:今天看到飛機起飛也不是

隨隨便便的就可以讓他飛的,以我們搞技術的眼光,我們是比較好奇人家的研發過程。

所以,人家真的有從他們既有所累積的科技技術,不斷地預估未來相關科技產品發展,

而不斷地投入研發與測試...這些就是人家為何可以永保國力競爭力的表現。

(我們國內投入許多電子產品開發資源不少,廠商也不少,諸如筆記型電腦多年了,

結果,號稱新一代的平版電腦觀念與成功產品,還是由人家所定義的...

唉~一樣所累積的科技技術基礎,結果怎麼差這麼多?...

這個應該跟我們自己的市場與歐美日市場規模大小無關吧!)

另外一點:就從我以前唸書所念的航空知識,套用在現今許多飛機外型與許多飛行觀念,

真的感覺越來差越遠了,也只能感慨說:科學基礎理論的東西不變之下,

所延伸的科學應用工程產品可以說是一日千里啊...

所以,充實基礎科學理論外,還是要多發展一些應用觀念啊

過年期間我有弄了一台市面上所流行的帶陀螺儀的玩具直昇機,我正在整理相關的

文章內容...改天再發表了囉!

美無人隱形轟炸機 試飛成功

美國海軍第一架無人駕駛的噴射引擎隱形戰機X-47B,4日在加州愛德華空軍基地首次試飛成功。
(路透)
美國海軍表示,諾斯洛普‧葛魯曼公司建造的X-47B無人駕駛蝠翼噴射轟炸機4日在加州愛德華空軍基地首次試飛成功。這是美國海軍第一架無人駕駛的噴射引擎隱形戰機。

在試飛過程中,這架外型有如縮小版B-2隱形轟炸機的X-47B在空中停留29分鐘,爬升的高度達1500多公尺。X-47B可自航空母艦起飛,完成攻擊敵人目標的任務後,自行返回航艦降落。

美軍高層將X-47B視為新世代無人飛機的一種。它可躲避雷達偵測,飛行1萬公尺,時速1000公里,比螺旋槳推進的現役「掠奪者」及「死神」無人飛機快得多。X-47B幾年後才會正式成軍,預定2013年在美軍航艦進行首階段試飛。

我們國內的各大科技公司不是也有國防役人員嗎?...那是不是在做國防高科技啊?!

Northrop Grumman-built U.S. Navy X-47B Unmanned Combat Aircraft Completes Historic First Flight

First-of-its-Kind, Tailless Aircraft Moves Closer to Carrier Trials in 2013


EDWARDS AIR FORCE BASE, Calif., Feb. 4, 2011 (GLOBE NEWSWIRE) -- Today, the Northrop Grumman Corporation (NYSE: NOC)-built U.S. Navy X-47B Unmanned Combat Air System Demonstration (UCAS-D) aircraft successfully completed its historic first flight at Edwards Air Force Base (AFB), Calif.

Conducted by a U.S. Navy/Northrop Grumman test team, the flight took off at 2:09 p.m. PST and lasted 29 minutes. This event marks a critical step in the program, moving the team forward to meet the demonstration objectives of a tailless fighter-sized unmanned aircraft to safely take off from and land on the deck of a U.S. Navy aircraft carrier.

A social media version of this release that includes photos, video clips, and additional quotes and background material, is available at http://www.irconnect.com/noc/press/pages/news_releases.html?d=209544

"First flight represents the compilation of numerous tests to validate the airworthiness of the aircraft, and the robustness and reliability of the software that allows it to operate as an autonomous system and eventually have the ability to take-off and land aboard an aircraft carrier," said Capt. Jaime Engdahl, the Navy's UCAS-D program manager.

Northrop Grumman is the Navy's UCAS-D prime contractor and leader of the UCAS-D industry team.

"Designing a tailless, fighter-sized unmanned aircraft from a clean sheet is no small feat," said Janis Pamiljans, vice president and UCAS-D program manager for Northrop Grumman's Aerospace Systems sector. "Commitment, collaboration and uncompromising technical excellence among the Navy, Northrop Grumman and the UCAS-D team industry partners made today's flight a reality. We are indeed honored to have given wings to the Navy's vision for exploring unmanned carrier aviation."

Taking off under hazy skies, the X-47B climbed to an altitude of 5,000 feet, flew several racetrack-type patterns, and landed safely at 2:38 p.m. PST.  The flight provided test data to verify and validate system software for guidance and navigation, and the aerodynamic control of the tailless design.

As with all test programs, first flight represents the culmination, verification and certification of pre-flight system data collected and analyzed by both the Navy and Northrop Grumman. Airframe proof load tests, propulsion system accelerated mission tests, software maturity and reliability simulations, full system taxi tests, and numerous other system test activities were all completed and certified prior to first flight.

The aircraft will remain at Edwards AFB for flight envelope expansion before transitioning to Naval Air Station Patuxent River, Md., later this year.  There, the system will undergo additional tests to validate its readiness to begin testing in the maritime and carrier environment. The UCAS-D program is preparing the X-47B for carrier trials in 2013.

The Navy awarded the UCAS-D prime contract to Northrop Grumman in August 2007. The six-year contract calls for the development of two X-47B fighter-sized aircraft.  The program will demonstrate the first-ever carrier launches and recoveries by an autonomous, unmanned aircraft with a low-observable-relevant planform. Autonomous aerial refueling will also be performed after carrier integration and at-sea trials.

Northrop Grumman's industry team includes GKN Aerospace, Lockheed Martin, Pratt & Whitney, Eaton, GE, Hamilton Sundstrand, Dell, Honeywell, Goodrich, Moog, Wind River, Parker Aerospace and Rockwell Collins.

Northrop Grumman Corporation is a leading global security company whose 120,000 employees provide innovative systems, products, and solutions in aerospace, electronics, information systems, shipbuilding and technical services to government and commercial customers worldwide.   Please visit www.northropgrumman.com for more information.

以我們搞研發技術,甚至說以機械的眼光來看,每一個起落架的收放動作,

甚至簡單的滑行動作其實都是需要經過不少的設計與測試驗證,

所以以下這一段測試影片才是值得我們所激賞的啦!

這才是真正結合許多工程領域所展現的工藝產品...否則,我們國內的未來教育與人才培育,

可能最後只會剩下電子或軟體人才培育而已!

---至少N 年前我就發現一大堆台清交的機械畢業生,甚至我所認識的一些朋友老同事...

都跑去幹半導體廠的廠務或是封測廠上班,甚至都轉行去寫程式了。

轉行沒有不對的...只是重複性的工作真的太多人做了。
