Yeah, but they were all well broken-in airframes when they were refitted with the guns and sensors.
Until last year I didnt know that in 1912 (yes 100 years ago) there was an international flying week held in my village. It was a contest for hydroplanes to determine which one would be used for the exploration of the Congo.
Last weekend we celebrated this event. One of the participants was a replica of a Donnet-Leveque, one of the contestants in 1912.
These are pictures of the event in 1912
These are pictures of last sunday
Thanks for the pictures GSP, I enjoy looking at obsolete technology. The pics of the rotary engine the replice are great....what a piece of art!
As archaic as that airplane appears, it still has some beautiful flowing lines. It's as though designers at the time didn't have a complete grasp of aerodynamics, yet somehow knew that the swoops and curves were the right thing to do. And don't even get me started on the engine. Art and machinery combined! Magnificent!
I have some more of the engine:
During the event there was also a fly-by of 3 biplanes from just before WWII (From the "Stampe-Vertongen" collection)
I wonder how much ram-effect was gained through centrifugal force accelerating the intake air in the round plenum and 'down' those intake pipes?
Probably spun too slowly to gain much.
"I wonder how much ram-effect was gained through centrifugal force accelerating the intake air in the round plenum and 'down' those intake pipes?"
Your assesment of none is probably right, but not due to centrifugal effect. The air followed a tortured path through the center of the crankshaft to get to the crankcase, then out the pipes to the heads. Yes, the crankshaft was hollow and attached to the fire wall What passed for a carbie was attached to the crankshaft :eek1
At least it wasn't a monosaupe engine that had the weird centrifugal valve in the piston crown to duct the mixture into the cylinder :huh
The rotaries are so fascinating, so much dead end technology. But absolute works of art in execution and in their day, they were the king of power to weight ratio and reliability in aircraft engines. :eek1
Their reign was short, roughly 1910 to about 1916 in terms of the best aircraft engines available. By 1916 they were obsolete but were being made in large numbers on both sides of WWI and stayed in front line service to the end. After 1918, they disappeared rapidly.
But they are still works of art.
Just flew over my workplace this morning about 11:25
It's going to do a pass around Disneyland tomorrow so will likely be going right over my house! I'll have the camera ready.
I know a little about the Wright bros at Kittyhawk and WW I aircraft but have never heard anything about the development in between. Anybody know of any good books, websites or documentaries?
I read a book several years ago titled "Barons of the Sky", written by Wayne Biddle.
It is basically a history of the aerospace industry in the U.S. What I found interesting is that the book tells the story of how names like Douglas, Martin, Lockheed, Curtis, etc. became such icons in the aerospace industry. Most of these guys started building airplanes in their backyards in the years just prior to WWI. Pretty fascinating to read how they grew their companies into such aviation giants.
Beeeeeeyoutiful. Needs to be posted in the Art of Engine thread as well.
Prototype engine will allow travel from London to Sydney in four hours
No throttle. Just a kill switch. Turning one way was far easier than turning the other.
I'd suggest A Dream of Wings by Tom Crouch.
Lancaster crew found from WWII. Amazing.
Thats pretty cool.
I have a bomb rack for one of those laying around here somewhere :huh
