The time is during WW2, of course. Its contemporary German turbojets, while vastly more efficient, had serious reliability problems. The ME626 had a time between overhauls of 50 hours, at least in the beginning.
Progress was quick and by the time of the Meteor (which barely saw active service before the war ended), it was an entirely different matter. ... Although I expect any still in service have probably been through several sets of engines, with improvements. My point was that a piston powered duct fan with afterburner could be built with wartime standard materials, and if correctly constructed could have an edge over contemporary prop fighters. As it were ... well I read somewhere that Il Duce was quite pleased to be able to say he now had a jet in his inventory, and when you have to serve under a dangerous despot, that would be an advantage in itself.

I'm no expert on the subject of planes, but this is a local legend: Beverley XB259
http://www.beverley-association.org.uk/html/259/259.htm I went in it a few times. Once on Paull airfield in the 70s, an done at Beverley Transport Museum. Now at Fort Paull. |

Almost exactly the opposite of the turbo-compound engine, which used exhaust gas from a piston engine to drive a turbine to drive a propeller. In it's ultimate form, I think there was no mechanical connection from the crankshaft to the prop, it was just a gas generator.

An hour?!? Wow! My understanding is also that Zeppelins proved at first to be unexpectedly resistant to attack once the fighters reached them. Large but very diffuse targets with relatively few crucial parts to shoot at. It took experimentation until fighter attacks became effective - I think shooting an entire load of incendiaries at a single gas bag was found to be the best approach. But once this was discovered it first drove the development of high altitude airships, then eventually convinced Germany to completely abandon Zeppelin attacks on London.

Reminds me in general concept of the Lockhead YO-3 used in the Vietnam War.
https://en.wikipedia.org/wiki/Lockheed_YO-3 A very quiet/high endurance plane designed to shadow enemy troops (at night) without being detected. Pretty much a prop-assisted glider. |

Has the Republic XF-84H Thunderscreech been brought up yet?
https://en.wikipedia.org/wiki/Republ...Thunderscreech Two counter-rotating forward props on concentric turbo-driven shafts. Apparently fast but also the loudest airplane ever made. The tips of the props were supersonic at operating speeds so the plane emitted constant sonic boom shock waves even when on ground that could incapacitate unprotected personnel, disrupt operations throughout an airport and were heard up to 25 miles away. |

I suspect most of you have heard of the B-58 Hustler but I will mention it in this thread because the Vulcan has already been brought up:
https://en.wikipedia.org/wiki/Convair_B-58_Hustler A supersonic nuclear bomber and IMO one of the sexiest most beautiful airplanes ever built (ignoring its grim mission). Relatively quickly made obsolete by events, but for me as a young boy this was exactly what a jet plane should look like! |

I kind of assume that the XF-84 is one of those "Things That Nobody Has Heard Of" That Everybody Has Heard Of.
Like somebody who doesn't really care about airplanes has probably never heard of it, but they don't care, so what's the point? Meanwhile everyone who does care about airplanes has heard about that crazy brown note airplane. |

However, the one you haven't heard of is the Valiant.
It was the 'insurance policy' in case the Vulcan and Valiant didn't work out. It was very 'conventional' compared to the Vulcan and Valiant and didn't stay in service as long. https://en.wikipedia.org/wiki/Vickers_Valiant |

I think you meant to say Vulcan and Victor.
I remember walking along the Crinan Canal as a teenager and experiencing the Vulcans practicing low-level runs. They were monsterous beasts, fantastic aircraft. |

It has been said about sailboats that if they look "great" (sleek and sexy) they usually sail great (with only a few exceptions). I suspect the same applies to airplanes.

Burnelli
The Burnelli lifting fuselage aircraft of the late 1930s. Very efficient design, it was a step on the way to modern lifting body, flying wing and spanloader technologies. Had WW-2 not intervened, with it's high demand for proven designs, the Burnelli concept might have succeeded.

To me the Victor looks like it was designed by someone who learned everything they knew about jet bombers from the Bell X-1. Advanced, but somehow also primitive. And those intakes just look saggy.
For me, the peak bomber aesthetic is probably the B-1B. But I'm also fond of the F-117 (which is a bomber despite its nomenclature). Its form is pure "interim", but also an absolute dedication to singular function: Lowest possible radar cross section. Only the most meager concession is made to the aerodynamic requirements of flight. Low RCS is everything. |

Victor had a constant critical Mach number across the entire wing and consequently a high cruise speed, the nose and tail, were also designed to the 'area rule' for the same critical mach number so the shape of the Victor had a constant critical mach number all over.
A similar looking aircraft was the Buckaneer, it had similar crescent wings for the same reason. |

Nah, the sexiest plane is the Airbus Beluga:
I like big fuselages and I cannot lie... |

Two of my favourite little-known aircraft are the stunningly unaesthetic Avro Bison and Blackburn Blackburn (so ugly they named it twice). For some unfathomable reason there was a decision made that naval spotter-reconnaissance aircraft needed a full-sized chart table and enough room for the observer to stand up inside the fuselage, but still needed to be small enough to operate from an aircraft carrier. There was a two-seat side-by-side trainer version of one that reputedly had so much drag that it could barely get airborne from the Fleet Air Arm's longest land runways, never mind a carrier. Fortunately they were never needed in a war; in any kind of combat they'd have been sitting ducks.

The current strategy seems to be to use the helicopter for covering a large area quickly, while its parent frigate or destroyer brings the big stuff up behind. Either the ship following up on contacts from the helo, or the helo covering the route of a contact being chased by the ship.
And a ship-helo team can stay out longer and operate in more conditions than a seaplane. |

I am surprised that this is true. The Seahawk helicopter, one of the current anti-submarine navy helicopters, has an endurance up to 3-1/5 hours and a range of 282 miles. Although there are no current USN seaplanes used for anti-sub patrol (AFAIK), many of the seaplanes used in WW 2, such as the PBY Catalina, had endurances of up to 31 hours and ranges of 2,500 miles - one of the main reasons they were so beloved for patrols.
This does not resolve the "operate in more conditions" issue but isn't that referring to the difficulty seaplanes have landing on rough water, rather than in flight? I imagine helicopters and seaplanes both (being relatively slow, bulky, and with low max altitudes compared to most jets) have similar problems in flight in storms, with the Catalina actually having slightly higher ceilings and max speeds vs helicopters. And notably landing a helicopter on a rocking aircraft carrier deck in high and gusty storm winds is probably very difficult - is it that much less limiting than landing a seaplane in a storm when the seaplane can travel thousands of miles to find smoother water? Am I misunderstanding the facts? |

Stereotypes aside, there doesn't seem to be any good information about how it happened. Some say it was to mislead the Soviets, or fit into some negotiation with them. Others say it was to attract the top pilots. Still others suggest it was an accident - just another meaningless anomaly in the application of the tri-service numbering system.

Also, as hilariously awesome as the A-10 is, it hasn't made a lot of sense, operationally or fiscally, in a long time. That's why the Air Force is trying to get rid of it. Modern CAS is being done more effectively by the F-16, F-15E, and the B-1B.
The age of the multirole fighter is upon us. Building a dedicated tactical ground attack plane today would be like building a dedicated night fighter. |

To be fair, it was the F-111 that initially muddied the waters; the F-111B would have been something that could reasonably be described as a fighter, but every F-111 (as opposed to FB-111 and EF-111, which definitely weren't fighters either) that actually flew had low level bombing and ground attack as a primary mission.

A ship-helo team can operate in more conditions than a seaplane. And while the helo's own endurance is limited, the destroyer it's flying from can stay on station for weeks at a time - in any weather. A seaplane that has to fly thousands of miles away to land is not going to be much use in hunting the submarine it left behind. When the USN does need that kind of trade-off, they just operate land-based ASW planes like the P-3 and the P-8.

Yep. And the F/A-18 should actually be the AF-18. And the F-15E should actually be the AF-15. The F-16 should probably be the AF-16, but at least in that case it was designed as a pure fighter, that later turned out to be flexible and upgradeable enough to be an effective multirole.

Exactly, I served on ASW Frigates in the RN in the 80s. We had an array of detection gear including variable depth sonar that could be lowered deep to detect subs 'hiding' in thermal layers. We had a helicopter that could be armed with AS torpedoes and depth bombs that we could send to engage any distant contacts and our own onboard weapon systems.
Most of the sensors were passive 'listening' devices, they could pinpoint and identify a particular class of sub and even individual boats. Active 'pinging' was only used as a last accurate 'fix' before a weapon was engaged. Bigger helicopters from carriers and cruisers carried 'dipping' sonars as well as sonobuoys and could locate and engage targets on their own. I am sure the sensors and systems are a lot more sophisticated today. |
