Re: B-47E last flight photo why the chute on landing ?
One post noted : ..SOP for landing a B-47 was to lower the rear landing gear and deploy the drag chute before landing. She was VERY CLEAN, VERY SLICK aerodynamiclly and took a lot to slow down for landing.
The B47 has a Bicycle landing gear and 2 chutes. The "She was VERY CLEAN, VERY SLICK.." aerodynamically is true but ALL the Landing Gear Wheels (including the outrigger wheels) go down with the Landing Gear Handle at one time (ie : Bicycle Landing Gear.
When the acft. got light after a mission (and the fuel load was mostly diminished) the throttles were at "flight idle" (at the min. throttle stops) to keep the acft. slow enough to put down the gear and land. The drag from the gear now being down was not enough to slow it down because of its Slippery Aerodynamic Design. Because the engines were at idle and when power was needed in this flight regime, the "fuel controller" (the unit delivering the fuel to the injector nozzles in the combustion section of the engines) were slow to react when instant power was needed to keep the desired precise airspeed until the 3-6 seconds it took to react to "the request for power" was established.
SOOOOOO ! A small "drag chute" was added for normal ops for landing to provide "needed drag that kept the engines spooled-up" so that the fuel controller at "this now higher rpm and thrust" acted faster (no or little time lag from "request to the power requested" was instant or close to instant.
THEN : when in the landing and the small drag chute was doing its job of "dragging" - an additional amount of drag was required to slow the B47 upon touchdown to brake use speed - the other of the 2 chutes I mentioned was gigantic in in respect to the "drag chute" and was named and is "the Brake Chute" - WHICH after the Bicycle Gear Trucks were on the runway "and or" called for by the pilot this Drag Chute was activated by a mechanical "T" by the co-pilot. "The Drag Chute" was activated by an Electrically Activated Switch - "The Brake Chute" activated by the mentioned Mechanically Activated "T" Handle.
At First the Drag Chute was also activated by a smaller "T" handle and resulted in "the fatal error" of "Brake Chute Deployment in Flight" . "IF" - YOU DID NOT GRAB AND PULL THE "BRAKE CHUTE RELEASE HANDLE" FAST ENOUGH YOU COULD THEN CLASSIFY YOURSELF AS "DEAD".
A Fellow B47 Pilot and I, while walking to the Officers Club for dinner one night, witnessed the deployment of the Brake Chute of a B47 on a wide down-wind leg (even though the above changes were in place). The B47 immediately slowed well below flight speed, nosed down and disappeared behind the treeline at McConnell AFB, KN. We ran to the OClub and called the Control Tower - they informed me that the Brake Chute Release Handle was pulled and the B47 came within 50 or so feet of being "permanently retired from service".
I have 2,400 hours in the B47 and my last flight was in Dec 1965 - it was a great Bird to Fly and one of the ones I flew now sits at the Museum of Flight, Boeing Field, Seattle ,WA. Carl J. Mollnow 10 mar 12
Welcome to the group Carl and thanks for the "Real" story. If you have any more stories or pictures of your time on the B-47, I for one, would love to hear them. As a person that has been fed and watered by Boeing products for the past forty years (Dad fixed 'em and now I do) I have a very soft spot for Seattle's finest!
