美帝的f22在高马赫时也能开弹仓发武器吗？

可以。试飞过许多极端条件了。极速下不知道，也许不能，反正巡航条件下没问题。

超音速应该不行
会被吹掉的...
一般飞机要求放起落架速度都要小于500左右
高了要么卡住放不下,要么嘣坏液压,要么舱门飞掉...有的干脆起落架飞掉的都有

至于弹舱,应该加强了,普通速度下应该没问题
不过超音速...估计不行

想像当中可以这么做！
不过很快超音速就变成亚音速继续飞了。如果飞机不损坏的话。

在超音速状态下投弹早就试飞过了，连投放JDAM，SDB这样的无动力炸弹都没问题了。AIM-120甚至在倒飞时试验过。
《兵器》杂志上曾经刊登专文介绍F-22的武器投放设备。专门提到在飞行包线边缘的武器投放实验，这是必须的，不存在超音速无法投弹的说法。

给个参考看看？

7/17/2008 - EDWARDS AIR FORCE BASE, Calif. -- On July 11, the 411th Flight Test Squadron passed a milestone as an F-22 Raptor travelling at supersonic speed dropped a GBU-39 Small Diameter Bomb for the first time.

The first supersonic SDB drop was part of a safe separation test currently being performed to integrate the bomb with the F-22.

The SDB is a 250-pound class precision guided munition capable of destroying high-priority stationary targets from Air Force fighters and bombers from stand-off distances.

"An SDB has never been dropped from a supersonic aircraft," said Maj. Michael Starr, 411th FLTS test pilot. "Supersonic separation testing will give the F-22 the ability to drop the SDB at supersonic speeds, which synergistically enhances the Raptor's air-to-air mission."

This was a critical step in achieving the goal of employing a "fully operational small-diameter bomb," said Capt. Chris Smith, 411th FLTS flight test engineer. The 411th FLTS is planning on performing more supersonic drops as part of this testing.

For safety purposes, the team based its test on a build-up approach, gradually increasing the aircraft speed and altitude.

"At first, we had to make sure the aircraft could carry the small-diameter bombs," Captain Smith said. "We performed ground vibration testing to ensure that any conditions wouldn't excite any structural modes of the F-22 and the bomb. We also did three rounds of pit tests, where we placed an F-22 over a specifically designed stores separation pit and performed numerous drops to verify safe separation of the bomb from the aircraft and to ensure we did not structurally overload the aircraft."

Performing ground testing ensured everything was in proper order before performing separation testing in the air, said Nicholas Chung, 411th FLTS air-ground weapons integration engineer.

"We started dropping small-diameter bombs from the F-22 at a speed of 0.8 Mach," Mr. Chung said. "We also performed eight subsonic drops prior to this milestone."

Currently, the F-15E Strike Eagle is the only aircraft outfitted with the SDB weapon system. Meanwhile, the F-22 carries two 1,000-pound Joint Direct Attack Munitions for its global strike role.

"Because of the size of the small-diameter bomb, the F-22 can carry more munitions at a time," Mr. Chung said. "Now, we are looking at carrying eight SDBs compared to just two JDAMs. This will allow the aircraft to strike up to eight targets at a time."

The team is performing the testing at Edwards because it is the only Air Force facility that performs developmental flight test on F-22s.

"Edwards has the resources in terms of both assets and test expertise," Mr. Chung said. "We really have an emphasis not just on the technical aspect but also the safety aspect of the testing."

Following a series of additional supersonic drops and after the 411th FLTS determines safe separation of the bomb from the aircraft, testers will begin dropping guided weapons, Mr. Chung said. This is to determine not only safe separation of the SDB from the aircraft, but also to see if pilots are able to guide it to the target.

"This capability is essential to give the F-22 further combat capability for the Global War on Terror," Major Starr said.

"Through Herculean effort and incredible skill, the (411th FLTS) engineers, flight test engineers, civilians and government contractors did an unparalleled job showcasing the fact that the F-22 Raptor is, and will remain, the world's most dominant fighter aircraft."

那就是说f22 发射的AIM-120就可以达到很远的射程了。

    他的结构有那么强?

海瑞罢官 发表于 2009-11-20 15:29


    使用同样的导弹，F-22凭借高空高速，确实能够得到比普通三代机大的射程。
不过还要考虑雷达能看多远。

是的，至少超音速没问题，极速状态下行不行就不清楚了。不过这个难点不是舱门结构，还有设法使炸弹和机身安全分离的问题。发射AIM-120和AIM-9的要求估计都没有投放炸弹严苛。

    如果超音速状态下不能发射武器，那么超音速巡航就没多大意义了。既然要超巡，这是个不得不跨过去的坎。毛五和我国的四代，既然要求要超音速巡航，自然就也必须有此能力了，

那武器本身应该不用作很大的更改吧？

ericcui1 发表于 2009-11-20 15:40


    确实，不能战术动作减速再发射

F22发射响尾蛇导弹的速度已经达到2马赫左右了， 发射AIM120的速度略低于这个速度，但也超过1.7马赫

    AIM-120系列的弹翼越来越小，还有研制SDB，都有照顾F-22携带的考虑。


上图是早期的，下图是后期的，可以对比一下弹翼形状。

F-22要的就是超音速飞行中发射导弹，还要能做大角度机动。
超音速和跨音速段的机动能力，应该是无敌的。

看来美国人的目标是要在2马赫的情况下投放MK-82级别的炸弹。

Air Force Basic Research Key to Successful Supersonic Bomb Release
by Molly Lachance (Anadarko/CIBER)
Air Force Office of Scientific Research
4/11/2008 - ARLINGTON, Va. -- An Air Force Office of Scientific Research (AFOSR)-funded program was crucial to the successful supersonic test release of an MK-82 Joint Direct Attack Munition (JDAM) from a weapons bay at Mach 2, or two times the speed of sound.

It was the first successful test release of any air delivered munition at this speed.

Researchers from the Air Force Research Laboratory (AFRL) and The Boeing Company conducted the test on a rocket sled at the 10-mile Holloman High Speed Test Track in New Mexico. They did so for a program called High Frequency Excitation Active Flow Control for Supersonic Weapon Release, or HIFEX.

Solving the supersonic weapon dispense problem involved stabilizing the air flow within the weapons bay as well as initiating a proper nose-up release trajectory. If these two conditions could not be met, the supersonic weapon release would be unsteady and therefore, unpredictable.

The HIFEX researchers needed a way to stabilize the weapon during release at such high speeds. They found an answer in a supersonic micro-jet actuator array, developed during an AFOSR program that sought a solution to a different problem.

In 1999, AFOSR awarded funding to researchers at the Florida A&M University and Florida State University (FAMU-FSU) College of Engineering--one of only a few research institutions supported through the congressionally funded, Historically Black College and University (HBCU) program. The research, initiated by Dr. Anjaneyulu Krothapalli and subsequently led by Dr. Farrukh Alvi, explored the use of supersonic micro-jets for flow control in applications associated with Short Takeoff and Vertical Landing (STOVL) aircraft.

In their flow control approach, the team arranged supersonic micro-jets, or nozzles, around a STOVL jet flow to minimize disruption at takeoff and landing.

To complement the expertise provided by Dr. Alvi's team, Dr. Anuradha Annaswamy of the Massachusetts Institute of Technology joined the effort and helped develop the control scheme used to dictate how and when the micro-jets would fire.

As Dr. Alvi's team was perfecting the results of its supersonic micro-jet research, the Defense Advanced Research Projects Agency (DARPA) began the HIFEX program, which emphasized more advanced flow control approaches.

Not long after the program began, DARPA requested that the FAMU-FSU team, in collaboration with Dr. William Bower of The Boeing Company, apply their micro-jet research to help achieve safe weapon dispense at supersonic flight speeds.

The supersonic micro-jet actuator array developed for STOVL applications proved to be a workable solution. The team found that when placed upstream of the weapons bay, the micro-jets reduced the unsteady pressures inside the bay and modified the flow outside the bay to ensure that the JDAM test vehicle flew out of the rocket sled on a proper nose up trajectory.

As a part of the new program, Dr. Alvi's team tested a 2 percent scale weapons bay model using a supersonic wind tunnel built for the program. They later conducted extensive testing of a 10 percent scale model at Boeing's Polysonic Wind Tunnel.

HIFEX transitioned from DARPA to AFRL as the project matured to a full-scale rocket sled demonstration. The researchers will conduct additional full-scale JDAM tests at Holloman Air Force Base in the near future.

"This work is a great example of the broad applicability of basic research and technology transition from the university setting to more applied efforts," said Dr. John Schmisseur, AFSOR program manager. "It also shows the strength of the research capabilities at FAMU-FSU, which in this case led the efforts of a team with members from a leading national research university."

    去看看《国际航空》2008年的吧

超音速不能开仓，怎么发挥超巡特点。设计师会考虑的·

[美国《洛克希德·马丁公司网站》2002年8月28日报道]编号为4003的F-22成为第一架在超音速飞行中成功发射雷达制导AIM-120导弹的"猛禽"战斗机。

  8月21日，在加利福尼亚州爱德华空军基地进行的试飞任务中，这架编号为4003的"猛禽"在太平洋上空约4000米高度，飞行速度为1.2马赫的情况下发射了这枚空-空导弹。


2002年就已经解决的问题今天还有人讨论。。。。。。。。。。。{:cha:}
