The demise of the Tri-Jets (new YT video)

[Garfly]

 

 

FROM THE YT DESCRIPTION:

"Once upon a time, airports of the world roared to the sound of three-engined commercial airliners, ranging from smaller regional craft like the Boeing 727 and Hawker Siddeley Trident, to flagship long-distance wide-bodies like the Douglas DC-10 and Lockheed Tristar. Today, though, they're all gone, their demise steeped in the inevitable rise of twinjets as focus shifted towards fuel efficiency and environmental considerations, something the trijets weren't equipped to handle."

The Boeing 727 was a rocket ship! It had greater sweepback to the wings than any other Boeing, so could go up to Mach .92, before shockwave separation Mach buffet occurred. Most airliners get up to around M.86. With three engines in the tail, if an engine failed, all you noticed in the cockpit, is the VSI needle sag by 200’/min! No asymmetric. In the cockpit, very little engine noise, just the hiss of airflow. Roll rate was very good, low and high speed ailerons and spoilers. Spoke to a pilot who said it handled like a fighter. Heavy fighter I guess! The tail air-stairs were brilliant, no support required at some small airports. Great pilots aircraft, but yes, sadly killed off by those three thirsty turbojets!
