The Titan IV was the last of the Titan family of rockets, originally developed by the Glenn L. Martin Company in 1958. It was retired in 2005 due to their high cost of operation and concerns over its toxic hypergolic propellants , and replaced with the Atlas V …

泰坦4是 泰坦34D 的增大型号：在泰坦34D的基础上，把固体火箭助推器、一级和二级加长，整流罩直径增加到5.08 m。 泰坦4A与泰坦4B的最大差别在于使用不同的固体推进剂助推器：泰坦4A使用2枚金属壳体的7段式固体推进剂助推器，泰坦4B则使用2枚复合材料壳体的3段式固体推进剂助推器，同时还改进了导航和电子设备以及使用新型地面处理系统，其地球同步轨道运载能力比大力神4A提高了25%。 泰坦4A于1989年6月首飞，1998年退役，总共发射22次，成功20次，成功率 …

The Titan IV was an extended length Titan III with solid rocket boosters on its sides. The Titan IV could be launched with a Centaur upper stage, the USAF Inertial Upper Stage (IUS), or no upper stage at all. This rocket was used almost exclusively to launch US military or Central Intelligence Agency payloads.

泰坦四号运载火箭由两枚大型固态辅助火箭及两节式的液态火箭所组成,发射后的前两分钟仅使用固态辅助火箭,发射约两分钟后才开启第一节液态燃料引擎。 第一及第二节的燃料使用50%的联氨及50%的 偏二甲肼 混合而成,而氧化剂则是四氧化二氮,这两种推进剂混合后能自燃 (于室温接触后即自行点火),也能于发射前存放在燃料槽中较长的时间。 泰坦四号运载火箭可从佛罗里达州邻近可可比奇 (Cocoa Beach)的卡纳维尔角空军基地SLC-40或41号发射台发射,也可由加利福尼亚州圣 …

The Titan family of rockets continued to support NASA and U.S. Department of Defense missions for nearly 50 years, and in 1990, the Titan IV was developed to become the nation’s most powerful launch vehicle capable of boosting critical national security satellites weighing over 12,700 pounds to geosynchronous orbit.

2025年3月1日 · 大力神四号系列运载火箭 (包括四A型及四B型)为 美国空军 所属的火箭 [1]，发射地点由 佛罗里达州 的 卡纳维拉尔角空军基地 [2] 及 加利福尼亚州 的 范登堡空军基地 [3]。 大力神4号运载火箭于2005年除役，倒数第二次任务 (B-30)于2005年4月29日从卡纳维拉尔角空军基地发射，而最后一次任务于2005年10月19日由范登堡空军基地发射 [4]。 大力神4号运载火箭的研发确保美国空军有 航天飞机 等级有效载荷量的火箭，大力神4号运载火箭可不加装末端节或两个末 …

The Titan IVB was the U.S. Air Force’s largest and most powerful expendable single-use rocket. It was a space launch vehicle used to place satellites into orbit. Titan IVB rockets boosted payloads into low earth orbit, polar orbit, or geosynchronous (stationary) orbit from either Cape Canaveral, Fla., or Vandenberg Air Force Base, Calif.

Titan IV was an extended length Titan III with solid rocket boosters on its sides. The Titan IV could be launched with a Centaur upper stage, the USAF Inertial Upper Stage (IUS), or no upper stage at all.

1997年2月23日 · The Titan IVB increased payload capability by 25 percent over previous Titan IV rockets, which were subsequently renamed Titan IVA. Although nearly identical to the Titan IVA in other respects, the Titan IVB introduced upgraded solid rocket motors manufactured by Alliant Techsystems, a company which had just recently purchased booster designer ...

The Titan IV is a heavy lift rocket booster that assured continued access to space for the nation's highest priority space systems, such as Defense Support Program and...
