If you are talking about American planes or what have you.. please use proper measurements like mph, feet, inches and miles..
ОтветитьJohn Glenn was the first American in Space?? One of JFKs Heros??
ОтветитьBack in the day, I built & still have the Revell Boeing SST model consisting of 2 planes, one in streamlined super sonic mode, the other with wings out, gear down, and nose drooping ready to land.
ОтветитьIronically, the UK and France argued about how to spell "Concorde."
ОтветитьSupersanek transport
Gotta go fast!! 🦔
In regards to the Boeing SST, someone involved in the project summarized it perfectly with the words "We can carry the passengers or we can carry the hinges".
Placing a swing wing in a passenger aircraft was always going to come at the cost of a huge compromise. Concorde barely survived as it was. We can only imagine how much more expensive tickets would've been if in addition to the passengers and luggage it had to carry massive hinges as well.
A SST on its last landing here at boeing field close to twenty years ago flew over ny home near the landing strip and i saw it and heard it come in for the landing.
ОтветитьYes, I was involved with the 2707, Mach 2.7 cruise
Its productivity was higher than any other airliner in terms of pax transported per year. The other was the not chosen Lokheed SST.
Back to Boeing 2707 : It was a very safe airliner , tripple redundant control surfaces, the initial swing wing was replaced with a delta shaped wing, considered safer, much safer.
Political maneuvering by Wiskonsin senator Proxmire killed the program, citing sonic booms and other non realistic effects for the people on the ground. After a while it was restarted but too late, layed off Boeing engineers busy on other projects
Sutter : you can't turn on and off a project like a spigot, so the 747 was pursued instead, which was not supported by the unpredictable Government and midgets like Proxmire.
Besides there is no SOUND BARRIER, the transition from subsonic flight to supersonic flight is NOT perceiveable to the pilot, only the Mach indicator tells the pilot that he passed Mach one.
This talk about turbulence is sheer nonsense, You are neighter a pilot nor an aerodynamicist, please correct this common missunderstanding:
No sonic Barrier
No shaking at Mach 1
Historians have no knowledge, what the actual temperatures at cruising ALTITUDE are Mach 2.7 at the cruising altitude of 11 km and above are well within metall skin temperatures not requiring titanium
Ts = Tambient( 1+0.2 Mach²)
Mach = 2.7
T ambient = 15 C - 6.5 deg per 1000 m altitude
T ambient at SL in Kelvin = 288 K
Do the math yourself.
“I think the 747 will be flying for the next 20 years”…. What year was this made? 😂 Im still flying the 747 in 2025 and probably will for the next 20 years of my career! 👨✈️✈️
ОтветитьMy grandfather flew the B29 he proud of about that ❤❤❤
ОтветитьJohn Glenn was not the first American in space, that was Alan Shepard. Glenn was the first American to orbit the Earth.
ОтветитьA big miss, it should have been updated and improved. If this plane was American, it would be still.flying today I'm sure.
A wonderful jet, and still the best looking plane around today.
Aviation was not born in France….Dec. 17 1903…in North Carolina…USA.
ОтветитьI still think the biggest problem was that the engine technology was not yet mature enough, especially since the Olympus 593 engine on the Concorde and the RD-36 on the Tu-144 had to run in fuel-consuming full afterburner mode to maintain Mach 2 speed. The planned Boom Overture will use a modern turbofan engine that will be very quiet on takeoff and thanks to its much more modern design, could run in afterburner mode at Mach 2 with way less fuel consumption.
ОтветитьTheir was only one winner Concorde the SST grew to big and aspersions exceeded technical ability and the 144 was a disaster and relied on copying Concorde that’s why it only had about 2o passenger flights and was relegated to cargo
ОтветитьLove the Soviet propaganda part. BTW did you know that the newest Russian airliner, "Russia's answer to Boeing and Airbus regional jets", that still hasn't been certified the MS-21 IS in development since 2007? 17 years and still no end in sight. That's what the West is up against! Everyone should tremble in horror, the Russians are coming! 😂😂😂😂😂😂😂
ОтветитьLet us be clear, America is a continent and not a country.
The United States of America does not represent an entire continent
