V-507 The F-14 That Wasn't Part Three

     After the visitors had passed the various information panels the pathway eventually led to the main event, the full size mock up. The mock up was placed in an open, well lit area for viewing and showing off the designs features.




     With the V-507, space was given to show the wing sweep design for it's aerodynamic and ship board handling qualities. The mock up also allows a full size representation of height of the aircraft along with the presentation of where the major components are housed in the airframe. 





     With the AN/AWG-9 Phoenix weapons system being central to the future F-14, the V-507 mock up was able to show the antenna installation along with the ease of access to the avionics boxes used for the system.

V-507 The F-14 That Wasn't Part Two

The V-507 Mock Up is Born

As was common practice in the industry since the 1930's, an Operations Specification, Request for Proposal or other documents were submitted to industry and brochures, reports were generated on the company's proposal. The proposals were evaluated and the top one or top two were selected to go further into the development stage with more detailed engineering being accomplished and a mock up built.The V-507 is was selected to continue on to the mock up phase. 

The visitor to the V-507 mock up was treated to a series of informational panels along the way to the actual mock up. These panels helped to tell the story of the V-507 and why it was the right choice for the US Navy. Although incomplete, the photos do give signifigant insight into the development of the V-507.



A configuration display was presented with models showing the evolution from the F8U-3 to the V-484, V-505 and eventually the final V-507 configuration.

The threat that needed to be countered was illustrated. This showed that the engineering team understood the challenges facing the new design.


The technical alliance of Vought, Dassault, and Lockheed shown with the contributions of each highlighted.
Vought
  • Navy Fighter Design
  • Movable Wing Technology
Dassault
  • Inlet Design
  • TF-30 Operational Experience (Mirage F2, Mirage G)
  • Swing Wing Experience
Lockheed
  • Air Force Fighter Design
  • Titanium Manufacturing Technology
To further illustrate the technical alliance a display of the inlet design was presented along with the metals used in the manufacture of the aircraft along with what components were using titanium.





Finally in the photos that were uncovered for this post are the spotting diagrams. As this was an aircraft for the US Navy the ability to move and store the design aboard ship is critical to the success.


The display shows different spotting arrangements and compares the V-507 to the F-4 that was the current shipboard fighter. It also shows the V-507 in the hangar with the various other types then on board ship.

That concludes this walk through of the V-507 information boards. As can bee seen in the photos there are other panels and places where the confidential information has been covered over. These were the only photos uncovered thus far of this display, which is amazing that they still exist!  

In the next installment of this series the mock up will be revealed.

V-507 The F-14 That Wasn't


The V-507 was Vought's entry into the VFX competition to replace the unsuccessful F-111B aircraft. Unfortunately, the V-507 lost out to the Grumman 303 design that was designated F-14 Tomcat and went into US Navy and Iranian service.





The design featured swing wings, twin engines with a single vertical tail along with a tandem seating arrangement for the crew. Missile load for the V-507 included the AIM-7 Sparrow, AIM-9 Sidewinder, AIM-54 Phoenix and M61 cannon.





In addition to the AWG-9 fire control system the V-507 also had a provision for a retractable IRST/TV under the nose of the aircraft.




Unfortunately, there was not a fly off and nothing more than a mock up was ever built.

CV10 prefixed drawings and part numbers are F7U-3 components and CV14 prefix drawings and part numbers are exclusively created for the A2U-1. 

The part number breakdowns reveal that the A2U-1 incorporated a number of F7U-3 components that were already in production. 

It is also interesting that to note the partial interchangeability of the speed brakes, upper left to lower right and upper right to lower left.

Below is a view of the AN7510-2 Plate that was to be applied to each major assembly identified in this drawing.

FLIR and LST Aerodynamic Testing on the A-7E

As a further addition to this posting concerning FLIR (Forward Looking Infrared) and LST (Laser Spot Tracker) installation on a YA-7D. Here is A-7E 156802 in February 1972 with FLIR/LST simulated fairings installed under the air intake. The testing would later lead to pod mounted FLIR and a chin mounted LST on the A-7D/K series only. The A-7D trials would actually start around a year later. For some images of that testing please visit my previous post here: FLIR/IRST Tests on YA-7D 67-14582
