海军参加的XC-142

1959 年美国军方根据一个咨询委员会的建议,启动一项旨在实用化的垂直起落飞机计划,特别要检验新飞机在实战条件下的,而且要适合三军(海军陆战队在 50 年代没有独立的采购计划,由海军代办)的需要,所以产生了三军联合的 XC-142 计划,LTV 的 Vought 分部得标,Hiller 和 Ryan 作为主要次级承包商,计划由空军主持。XC-142 可以装载 32 名士兵,比 30 年后的 V-22 还多 40%,四台发动机和 5 个螺旋桨(4 个推进螺旋桨加一个机尾的姿态控制螺旋桨)全部交联,所以只有还有一台发动机在工作,5 个螺旋桨都会转动,尽管可能动力不足。空军对 XC-142 作了大量的测试,包括空运、空投、沙漠、山地、航母、搜索救援、装载机动车辆等。XC-142 最后还是坏在机械复杂性上,可靠性不够,而且机翼在 35-80 度倾转范围里,机翼像门板一样,受横风影响太大,发动机差动推力的控制不够灵敏。最大的抱怨是机翼倾转过程中,差动的辅翼有横滚控制变为偏航控制,而差动的发动机推力由偏航控制变为横滚控制,这不光是一个操作习惯的改变,还在机翼倾转的过程中,横滚控制和偏航控制交联,要求飞行员作大量复杂的补偿动作,工作量太大,而且机舱内噪音和振动太大,估计和在接近垂直状态而低速前进时,刚性的螺旋桨对非对称升力不作补偿,振动全传到机舱里了。XC-142 在 67 年下马了。1959 年美国军方根据一个咨询委员会的建议,启动一项旨在实用化的垂直起落飞机计划,特别要检验新飞机在实战条件下的,而且要适合三军(海军陆战队在 50 年代没有独立的采购计划,由海军代办)的需要,所以产生了三军联合的 XC-142 计划,LTV 的 Vought 分部得标,Hiller 和 Ryan 作为主要次级承包商,计划由空军主持。XC-142 可以装载 32 名士兵,比 30 年后的 V-22 还多 40%,四台发动机和 5 个螺旋桨(4 个推进螺旋桨加一个机尾的姿态控制螺旋桨)全部交联,所以只有还有一台发动机在工作,5 个螺旋桨都会转动,尽管可能动力不足。空军对 XC-142 作了大量的测试,包括空运、空投、沙漠、山地、航母、搜索救援、装载机动车辆等。XC-142 最后还是坏在机械复杂性上,可靠性不够,而且机翼在 35-80 度倾转范围里,机翼像门板一样,受横风影响太大,发动机差动推力的控制不够灵敏。最大的抱怨是机翼倾转过程中,差动的辅翼有横滚控制变为偏航控制,而差动的发动机推力由偏航控制变为横滚控制,这不光是一个操作习惯的改变,还在机翼倾转的过程中,横滚控制和偏航控制交联,要求飞行员作大量复杂的补偿动作,工作量太大,而且机舱内噪音和振动太大,估计和在接近垂直状态而低速前进时,刚性的螺旋桨对非对称升力不作补偿,振动全传到机舱里了。XC-142 在 67 年下马了。
After the end of World War II and during the Korean War, the helicopter demonstrated its versatility for hovering flight in support of ground troops and for rescue. However, the large diameter rotor required for hovering flight compromised forward flight speed, payload and range. Because of this, both the military services and the aircraft industries were conducting studies (costing over $200,000,000) of aircraft configurations that would provide an aircraft with both a hovering capability and a short takeoff and landing (V/STOL) capability. Flight controls should be similar to those in helicopters during hover and conventional aircraft in forward flight. Early in the 1950’s, the first generation of V/STOL aircraft emerged as tail sitters, wire hangers and hybrid helicopters.  Technically they were considered a success since they flew with some degree of control and their performance as demonstrated for short periods at air shows was spectacular.  However, V/STOL aircraft were clearly not developed sufficiently for operational use.  Lockheed developed the XV-4A, Ryan developed the XV-5A lift-fan aircraft, Curtiss-Wright developed the X-19 and Bell developed the ducted-fan X-22. In Canada, the tilt-wing CL-84 was Canadair’s V/STOL demonstrator, while Germany’s Dornier Company developed the DO-31. The three major military services (Army, Navy and Air Force) considered that this flying hardware experience would support the development of a prototype V/STOL airplane that could augment helicopters in transport-type missions. If this prototype program was successful, an airplane based on the prototype experience could be developed. Professor Perkins of Princeton conducted a V/STOL study for the Department of Defense in 1959.  This study helped create the XC-142A tilt-wing V/STOL program.

The three services jointly developed a Request for Proposal (RFP) for a V/STOL transport airplane that could be evaluated in an operational environment.  The RFP was issued to all interested helicopter and aircraft manufacturers in January 1961, with manufacturers’ proposals due in April 1961. The U.S. Air Force was the procuring service.
短、粗,没有多余的评价了!

Later in the program it will make vertical takeoffs by tilting its wing upwards and transitions from vertical to horizontal flight. Built by an industrial team of LTV, Ryan and Hiller, the XC-142A is powered by four T-64 turboshaft engines built by General Electric and driving four 15.5-foot Hamilton Standard fiberglass propellers.

现在V22也好不到哪~

长的好可爱哦

挖哈哈哈哈哈哈哈哈哈  :lol :lol
先驱们

      美国希勒飞机公司的 X-18 是美国研制的第一种可倾转翼飞机,说它是后来 XC-142 和 V-22“鱼鹰”的“祖先”一点也不为过。X-18 的机体是在蔡斯 YC-122C 运输机的基础上改进而来的,安装的两台艾立森 T40-A-14 涡轮螺旋桨发动机来自美国海军的 XFY-1/XFV-1 立式起降战斗机。X-18 机长 19.20 米,机高 7.49 米,翼展 14.63 米。
  1961 年 7 月,X-18 在它的第 20 次试验飞行中一个倾转翼发动机发生了故障,飞机随即进入了螺旋。虽然 X-18 在坠毁前的一刹那被机组成员成功降落,但与地面碰撞后的机体还是有很大的损伤。这之后 X-18 再也没有飞上蓝天,只在地面上进行一些测试。最终 X-18 试验项目被取消,唯一的一架也被拆解当作废品买掉了。
有创新的思想
有创新的工艺
不厉害都不行
像个大遥控玩具
确实挺可爱的,呵呵,不像是杀人兵器嘿嘿。。。:lol :lol
造型很可爱
象卡通:D
如果不搞成90度倾转角,只搞到45度或者30度什么的。
也就是说放弃垂直起降能力,只要求短距起降,V-22这类飞机的安全性能不能得到提高?
超级油老虎,运载力小
这几乎是判了运输机死刑么
这种类型的飞机是机翼活动还是发动机活动的技术要求低?
功能太诱人~~:D
V22要是背个盘子的话不就无法折叠机翼了?
V22的大哥吗,
尾巴还有个发动机 有意思
一个大怪物!!
实在是太可爱咯
中国也可以搞这种飞机做舰载预警机吗?

不新发帖了,希望不要因为挖坟而被扣分。。。。
楼主总是能弄到好东西。  有23型近期的照片吗?
