當時在一陣大地晃動後被震醒
次日從電視上看到東星大樓倒塌的消息

小貓不會作模型，小貓只愛玩模型；看似小貓玩模型，其實模型玩小貓：
A B 補土白膠條，樹脂改套蝕刻片；凹線凸線凹凸線，乾磨水磨銼刀磨；
水性油性消光漆，乾掃手掃噴槍掃；模型一盒三百幾，零件一堆三千幾；
多買多作進步多，買了不作口水多；花錢耗時傷精神，小貓是隻敗家喵。 |

如果真的中部到時候不下雨...
俺就可以檢驗某親戚的烤肉技術了...
之前每次家庭聚餐都會聽到說他老大烤肉、尤其是烤牛排技術多好多好...
甚至誇耀說可以幹掉一般平價烤牛排店(一般的便宜鐵板牛排就不用說了)...
希望真的不會下雨啊~!
最近看18、19台一些介紹科技演進的節目就不錯...
至少都看得懂啦...

看到介紹第六期Military Axis的部分內容,這次一改往日以二戰為主而講起日本F-X計畫參賽機了.有趣的是,用胸圍比擬RCS與載彈量,於是,當講到F-22的"胸圍"時,背景音樂響起"Turn A Turn,Turn A Turn,Turn A~~!"難得會覺得低RCS不好......

至於F-15E呢?那當然是大到可以當凶器的巨乳...... |

我斷我斷我斷斷斷~~
宗申的
新車250cc倒是很漂亮
另外一輛
到對岸買機車騎機車;還是小心點好
外型到是有合乎國際標準啦
不過想想國內不長大的兩陽,尤其萬年野狼
唉...

啥鬼啦！剛剛迎接在下回到桃園的明明是大太陽！
------
早上去上課時桃園也是出太陽(不大)，結果到台北竟然下大雨，鞋子都淋濕了，下午沒課決定回家(不然腳悶在濕掉的鞋子裡也不舒服)，回到桃園又是個大太陽，真是討厭
看來得在背包裡準備個雨鞋套了，不然雨傘只能擋上半身，對下半身根本毫無防護效果，話說該去買腳踏車了，可是雨衣要放哪兒？難不成要放在車上給人家偷？

今天桃園的天氣很混亂
下午一點多的時候龜山和林口都有下雨
而且下的還不算小
可是去到監理所附近卻是大太陽
往北邊和西邊看可以看到大片的烏雲
回到市中心又開始飄雨.... |

大園這邊(公司, 機場起降航線正下方)的話是真的有下雨,
加上今天風大, 下午兩點多以後雨一陣一陣, 有的時候根本是用噴的.... |

我有點懷疑那傢伙我認識
因為他說的ge原廠資料
我手邊也有
看了一下
和他說的差不多....

未通過燃燒室與通過燃燒室氣體的百分比,不就是旁通比嗎?
這傢伙應該去找本比較一般的引擎教材,只要有畫J58引擎各速度運作方式的,就可以讓他仔細研究了. |

他該修看的是熱機課本..........
哪一個熱力循環沒有壓縮這一段阿？
他拿出來嗆的那一本書，好像是某本書的精簡版........而且是教授不愛用的那一本

The Ramjet
The ramjet engine consists of an inlet, a combustion zone, and a nozzle. The ramjet does not have the compressor and turbine as the turbojet does. Air enters the inlet where it is compressed and then enters the combustion zone where it is mixed with the fuel and burned. The hot gases are then expelled through the nozzle developing thrust. The operation of the ramjet depends upon the inlet to decelerate the incoming air to raise the pressure in the combustion zone. The pressure rise makes it possible for the ramjet to operate. The higher the velocity of the incoming air, the more the pressure rise. It is for this reason that the ramjet operates best at high supersonic velocities. At subsonic velocities, the ramjet is inefficient and, in order to start the ramjet, air at a relatively high velocity must enter the inlet.
The combustion process in an ordinary ramjet takes place at low subsonic velocities. At high supersonic flight velocities, a very large pressure rise is developed that is more than sufficient to support operation of the ramjet. Also, if the inlet has to decelerate a high supersonic velocity air stream to a subsonic velocity, large pressure losses can result. The deceleration process also produces a temperature rise and, at some limiting flight speed, the temperature will approach the limit set by the wall materials and cooling methods. Thus when the temperature increase due to deceleration reaches the limit, it may not be possible to burn fuel in the air stream.
Turbojet/Ramjet Combined Cycle Engine
This type engine operates as an afterburning turbojet engine until it reaches high Mach when the six large tubes bypass flow to the afterburner. When these tubes are in use, the compressor, burner, and turbine of the turbojet are essentially bypassed and the engine operates as a ramjet with the afterburner acting as the ramjet's burner.
GE教材論述到發動機類型的時候寫的
但是沒有像他提到的那樣詳細的說明
或許教材不一樣?
我依照上面那段文字拜了GOOGLE大神以後發現以下網站
好像的敘述喔....整頁和手邊GE教材幾乎一模一樣
到底誰抄誰ㄚ?

這麼簡單的文章就要嗆人?
不過偷說一下,PW與RR當年都開發過那種靠氣動力衝壓的引擎,而且還都有服役,偏偏GE沒有,你拿GE的東西,定義恐怕就與人家的不一樣......不過要說後燃器本身可以當成一種Ramjet可能也不是說不過去,但是真正實作的Ramjet沒一個那麼簡單就是. |
