Don’t get me wrong, I’m not questioning the rationale of UCAVs in general – it’s just that I’ve seen enough projects ‘grow’ themselves into cancellation that I have serious doubts as to the current direction J-UCAS is going. The ‘original’ UCAV designs from the 1990s (8-12K weight, SSB payload) seemed to offer a better justification than an F110-powered X-47B. We’ll have to wait & see whether it survives.
Indian1973 & Tmor – you might want to have a look at the new ducted-fan UAV proposed by Kestrel Aerospace in the UK. I’m sure I saw the same design in T3…!
The F120 used a combination of a fixed bypass between the first and second stages of the compressor (all-axi, to answer Over G’s question) with blocker doors on the fan duct which when closed allowed the transition to a leaky turbojet for supersonic cruise flight. OPR was approx. 35. The F136 derivative (alternate engine for the F-35), although based on the F120 core, is a non variable cycle engine (though there *were* rumors as to the use of YF120 tech post-ATF deselect…).
The MiG SM-50 (MiG-17 with a liquid rocket) came close, as would have the rocket-equipped Lightening (though since it was a double Scorpion, I guess that would have been four…).
The most insane three-engine fighter has to be the Polikarpov I-152/DM-2. A biplane with two ramjets. That’s what comes of state-sponsored vodka !
Unmanned air vehicles flying simulated missions. I miss the good old days of Buffs dropping sticks of Mk117s !
I’m still not convinced whether the larger X-45C (and the even larger X-47B) are the way to go. With systems this expensive – and the USAF has admitted that the initial acquisition cost of UCAVs will actually be pretty similar to manned a/c – will forces really be willing to risk them in dull, dirty and DANGEROUS missions like SEAD ?
The three Hueys are all 214 Ishafans (the IAF also has a handful of AB212s, which look similar from the frontal angle (with near-identical intake/fairing contours), but I’m fairly sure all your birds are Lycoming powered).
The two ‘civvy’ birds are the Panha 2061 (reverse-engineered AB206 JetRanger, subsequently ‘replaced’ by the equally-reverse-engineered Shahed-274 and Shahed-278) and Panha 2-75 Shabaviz (reverse-engineered AB205A Huey).
The two birds in the air are Bell 214 Isfahans. The aircraft on the ground is an AB205 (or a locally-produced Shabaviz 2-75. My money’s on the former !).
There’s a clue on the rear fuselage 😀
You say tomato, I say tomato, Boeing says joined wing, Lockheed Martin says box wing (“now with wing[let]s”).
Some good pics and first-hand insights into flying the Hind here: Pprune Mi-24 thread
Probably one of their Common Support Aircraft (CSA) proposals. CSA ran out of money, and the role has reverted back to the E-2, S-3 and F/A-18E/F.
Most figures suggest 700 in service. How many of those are actually operational is another matter…!
Can’t comment on the new lid, but the IRST will be fitted to the fleet downstream (I’d guess 2007/8). The PIRATE sensor package was not intended to be available for IOC, but will be part of the multi-role FOC spec. Productionization contract was awarded last year.
Good to see the Euros have twigged onto the block concept (“No congressman, it’s not late, it’ll just be added in a later block…”) :diablo:
It’s a fluid number because of operational losses, but in summary the Army acquired 821 A models, of which 501 have already been upgraded to D standard, with another 96 As (out of the total remaining fleet of 213) currently undergoing upgrade.
At the conclusion of its recently-launched Block III upgrade, the Army plans to have a total fleet of 597 AH-64D Block III Apaches, with 117 AH-64As remaining unmodified (and with total losses and cannibalized assets equaling 107 aircraft).
I was ignoring Albacore since she was only an experimental vessel.
SSKs aside, I’d nominate Skipjack as one of the most influential designs, since it represented a substantial leap-forward in hull design and speed. Okay, it wasn’t perfect (notably wrt acoustics), but for its time it was a major breakthrough.
Most successful ? Much as I’d like to nominate one of the deep-diving Russian SSNs, I would have to choose the Ohio class. They don’t get as much attention as the SSNs or SSKs in the post-Cold War era, but the fact that these vessels are still pretty much unchallenged 30 years after being designed speaks volumes for their total system design.
Couple of points. Firstly, if you believe the marketing speel, the Skyflash was a wunder-missile, with significantly better capabilities than the E model Sparrow. It was probably out-ranged by the AIM-7F/M (of little relevance given real-world ROE), but its targeting capabilities were allegedly still comparable with the newer missiles.
Secondly, IIRC the F-4M was a genuine swing role aircraft. Little in the way of guided ASMs, but it trucked a fair number of BL755s across Welsh firing ranges.
That said, the slats and internal M61 do it for me.
Great choice of pics for comparison btw.
