It may seem like I'm going off the reservation again with this topic but it does, peripherally, pertain to a airplane operated by the U.S. Navy.
It is also a work in progress, since I personally don't have a lot of material to work with. Gerry Asher has yet to fully weigh in, so there will be changes. Since I posted it today, I've modified the source of the second and the final tank to be Fletcher Aviation Corporation, an aerospace manufacturer that subsequently became Sargent Fletcher a decade or so later.
The P-80 wing tip incorporated a shackle from which to hang a jettisonable fuel tank or 1,000-lb bomb (the requirement to do both dictated its location under the wing; otherwise the tank would have been mounted in-line on the wingtip to maximize the end-plate effect).
The original 165-gallon tip tank was a thing of zaftig beauty, with a rounded nose and sculptured afterbody, that was mounted directly under the wing tip and smoothly faired into it.
Note the flange going from nose to tail on the top and bottom of the tank since it was assembled from two halves.
This tank was sometimes dropped in flight or otherwise damaged and needed to be replaced. As a result, a cheaper design was procured from Fletcher.
Note that it has a pointed nose, a constant-diameter midsection (barrel), and a more conical afterbody. It would appear that this tank was manufactured in three sections: forward, mid, and aft that were then assembled together.
However, Lockheed, Fletcher, or some other source designed and manufactured yet another tank that had a higher fineness ratio and a rounded nose. This tank is frequently seen on RF-80s:
And also on most U.S. Navy TO/TV-1s:
And on early T-33s and F-94s:
Note that it appears to be slung somewhat lower than the other tanks with a fairing enclosing the attachment to the wing. This is my best guess as to its size and shape.
The final F-80 tank, similar in configuration to the Misawa tank, was also procured from Fletcher. It was mounted inline with the wingtip rather than under it and sported a side-mounted fin on the afterbody. It increased the capacity of the tip tank to 230 gallons.
I'd appreciate information on and links to drawings and dimensions of these tanks.
The US Air Force installed Stanley's Yankee escape system in its A-1E Skyraiders as well as its single-seat ones. The Navy incorporated it in single-seat Skyraiders in at least two attack squadrons late in their fleet service but not in any of their wide-body A-1s.
From a Stanley Aviation Brochure:
From Ed Barthelmes excellent A-1 Skyraider Walkaround*:
In response to a discussion about C-130 wing dihedral:
The outboard wing panel had 2.5 degrees of dihedral, probably measured at the trailing edge.
Note that this drawing is from a Lockheed C-130 (no revision letter) so it shows an outboard location for the external fuel tank.
As a result, the wing was not flat across the top as shown by the red line in the front view above and by comparison of the airfoils on the side view here, at least statically when there was no fuel load:
Some say that when the airplane was fueled (all of it was in the wing, most in the outboard wing panels) that the wing was flat across the top.
The shape of the aft part of the engine nacelle of the excellent 1/48th Zoukei-Mura F-4J Phantom has been questioned. For what it's worth to the discussion, this is a depiction of the cross sections from pretty good drawings produced by McAir. Note that it depicts the Blue Angels F-4J, almost all of which had the F-4B J79-8 engines installed. However, the nacelle shape of the F-4B/N/J/S forward of FS 493, i.e. the unpainted "finger plate" surrounding the afterburner nozzle was the same.
The F6U catapult hook mechanism (and hold back, not shown), located aft of the nose-landing-gear well, was retractable and covered by two access doors.
One of many changes during the Pirate's development was to add a link/case chute on the belly, directly under the catapult mechanism location, to channel the links and cases from two of the cannons aft, safely past the engine intakes.
So what happened to the catapult mechanism or its access? After more closely examining a picture of the F6U bailed to NACA up on jacks and a closeup picture of the chute itself, I realized that there were actually two side-by-side chutes, each mounted on one of the catapult access doors.
It acts on a bellcrank that rotates the landing gear up and down. Note that the actuator is fully retracted when the gear is down so no piston is showing as when an actuator extends to put the landing gear down. Note the slot in the actuator end fitting that is connected to the bellcrank for the latter to slide inside it as actuator extends fully as the gear retracts. In other pictures on the link you'll also note that the hydraulic lines are missing but the requisite hydraulic fittings are on the actuator.
In 1956, at age 12, I lived on NAS Sangley Point in the Philippine Islands. Always enamored with airplanes, I imprinted on the Cougars, Banshees, and Skyraiders then being deployed. Not able to be a Naval Aviator because I was nearsighted, I instead became an aeronautical engineer and general aviation pilot. Now retired, I write books and monographs on U.S. Navy aircraft.
