USAF looks for new ejector seat
https://www.flightglobal.com/news/ar...-eject-456612/ US Air Force begins search for Next Generation Ejection SeatThe US Air Force started a market assessment to identify potential sources for its Next Generation Ejection Seat. The service is looking for a modern ejection seat replacement to be installed in a variety of aircraft, including the Fairchild Republic A-10 Thunderbolt II, McDonnell Douglas F-15 Eagle, Lockheed Martin F-16 Fighting Falcon, F-22 Raptor and Rockwell B-1 Lancer, it says in an online announcement. The competition has not yet been officially opened and the USAF did not announce a date when it would start accepting bids. Likely bidders for the forthcoming competition include Martin-Baker and Collins Aerospace, two of the US military’s leading suppliers of ejection seats. The USAF wants a seat that can safely handle ejecting a pilot with a weight range of 62.6kg (138lb) to 153kg (337lb). Total weight includes aircrew nude weight, aircrew flight equipment weight and survival kit weight. The USAF’s requirements specifies the seat should be able to eject at speeds up to 600kt (1,111km/h) and at altitudes from 0ft to 60,000ft. The recovery parachute’s vertical descent velocity should not exceed 1,380ft/min (7.01m/s), and should be steerable to a minimum turn rate of 20°/s. |

You forgot about the size and weight of Men's Wallets and Ladies Purses in the new politically correct bonus happy USAF.

SASLess. This competition has been 'ongoing' for some time. Some serious lobbying of USG has (allegedly) been going on in attempts to keep the contract 'in (Dons) house'. The following self explanatory open letter to Forbes Magazine makes very interesting (if you are that way inclined) reading. I believe it was published. LETTER TO THE EDITOR OF FORBES - Martin-Baker False news? Level playing field? Protectionism? - I couldn't possibly comment. |
Is it too much to ask, ORAC, for you to use the correct terminology in your title?
You wrote: USAF looks for new ejector seat The title is: US Air Force begins search for Next Generation Ejection Seat In the US, we call them ejection seats. Given that it's the USAF who is the topic of the article ... Or were you in such a hurry to cut and paste that you could not be bothered to check for accuracy? (Yeah, I have fallen afoul of that myself in the past ...) |

I didn’t cut and paste - I used the words I wished....... “When I use a word,” Humpty Dumpty said, in rather a scornful tone, “it means just what I choose it to mean—neither more nor less.” “The question is,” said Alice, “whether you can make words mean so many different things.” “The question is,” said Humpty Dumpty, “which is to be master—that's all.” |

Subtract the weight of the flight equipment and the survival kit from 62.6 Kg and you have a VERY light-weight nude pilot.

I wonder what the acceleration numbers are like on the latest seats, spinal injuries were very common on early “bang” seats with their huge initial acceleration, but the later rocket seats helped immensely. I recall reading that experiments with soft seat cushions as opposed to hard cushions actually resulted in worse injuries. Ejection seat technology is fascinating. |
At the end of the day (which appears to be of infinite length!) it will come down to 'nice to have' or 'must have' in the minds of the brass hats.

They will be dusting down the old meat box :) |
Lonewolf - ejector/ejections seats? You say flight suit, we say flying suit, you say airplane we say aeroplane, you say (eg) 214th Squadron, we say 214 Squadron, etc. Does it really matter? We both know what the other is talking about. :)

Here's a reason why to get it right, TTN.
A Triple Ejector Rack carries bombs. See also here The Ejection seat carries the bomber(as in, the person bombing). If you spend enough time in the military you learn the need for correct terminology. |
We say 'EJECT'; you say 'BAILOUT'.
We do of course, bail-out water from the bottom of the survival dingy to stop our bottoms getting wet. Conversely, you get your fannies wet, which can surprise us. None of this matters. |
Lonewolf; Expect incoming from TTN. I suspect he has more military time than you. And on a real aeroplane (English spelling) to boot.

We say eject on aircraft with ejection seats. We say bail out on aircraft without them. Just so that you understand the difference, for over 30 years the USN's primary trainer was the T-34C, which required a bail out under various conditions. For 20 or so years before that, the T-28 B and C were also bail out/parachute equipped primary training aircraft. At the same time, the advanced trainers -- T-2, TA-4, then T-45, were all ejection seat aircraft. Likewise the T-37/Tweet. Primary training, ejection seat, and we still say eject. Likewise in the T-6 Texan II. Old adage among the American carrier pilots: "There are those who have ejected, and those who will." @Herod: Our military has DOPMA, yours does not. After 25 years, my up or out choice was to choose to stay until 28, one last assignment somewhere else, or to hang up the cleats and stay where I was. With the kids settled in schools, and the wife finishing her degree, it was time. I was never going to be an admiral. Bring it. |
