  5. Facts from Lockheed’s codeone magazine https://www.codeonemagazine.com/article.html?item_id=137 By the late 1960s, Pratt & Whitney was designing and testing a three-bearing swivel nozzle for use on the Convair Model 200 Sea Control fighter. Design drawings dated 1967 show detail design layouts. The first nozzle was built and tested on a Pratt & Whitney JT8D in the mid 1960s. The tests included operating the nozzle in full afterburner with the nozzle deflected ninety degrees. The test rig was positioned to exhaust upward to avoid heating the ground under the test stand, though subsequent tests positioned the nozzle downward at the ground to assess the effects of ground proximity back pressure on nozzle performance. http://www.codeonemagazine.com/article.html?item_id=137 A great deal of misinformation has appeared on the Internet regarding the relationship of the Soviet Yak-41 (later Yak-141), NATO reporting name Freestyle, to the X-35 and the rest of the JSF program. The Pratt & Whitney 3BSD nozzle design predates the Russian work. In fact the 3BSD was tested with a real engine almost twenty years before the first flight of the Yak. Yakovlev was looking for money to keep its VTOL program alive, not having received any orders for a production version of the Yak-141. Lockheed provided a small amount of funding in return for obtaining performance data and limited design data on the Yak-141. US government personnel were allowed to examine the aircraft. *However, the 3BSN design was already in place on the X-35 before these visits*. -------- Yak copied the same flawed 3 engine hot cores design from Convair Model 200. F-35 has a single-engine hot core. Yak 141's forward hot air flow degrades the main engine's effective thurst.

  22. EVIL GUNNEY, I already posted in counter arguments in https://www.youtube.com/watch?v=N1Z_DuF87Sc LOL. Basic Wing loading without body and vortex lift. F-35A Empty weight: 28,999 lb (Year 2015). Wing area: 460 ft² Wing loading: 63.04 lbs/ sq feet F-16C Block 52 Wing area: 300 ft² Empty weight: 18,900 lb Wing loading: 63 lbs/ sq feet Tiny wings? F-35A's empty weight is 1.54X scaled from F-16C. F-35A's wing area is 1.53X scaled from F-16C. F-35A's 43000 lbf thrust is 1.50X scaled from F-16C's 28600 lbf. There's a near straight scaling between F16C to F-35A. From http://breakingdefense.com/2014/06/gen-mike-hostage-on-the-f-35-no-growlers-needed-when-war-starts/3/ General Mike Hostage On The F-35 vs F-16 The F-35, he says, has “at least” the maneuverability and thrust and weight of the F-16. The F-35 is to the F-22 as the F-16 is to the F-15. F-35A's main target goal is to replace current service F-16C. Apples to apples comparison based on F-16C's 550 Km combat radius F-35A (Year 2015 build). Set Combat Radius 550 km F-35A has 1407 Km combat radius Empty weight: 28,999 lb Wing Area: 460 ft² Weapons: 2000 lb Fuel: 7230.916844 lb Fuel load based on F-16C's 550Km combat radius Combat load: 38,230 lb Wing loading 83.11 lbs/ sq feet Thurst MIL 28000 lbf Thrust WET 43000 lbf Power-to-Weight: 1.12 :1 F-16C Block 52 Combat Radius 550 km Empty weight: 18,900 lb Wing Area: 300 ft² Weapons: 2000 lb Fuel: 7000 lb Combat load: 27,900 lb Wing loading 93.00 lbs/ sq feet Thrust MIL 17,800 Thrust WET 28,500 lbf Power-to-Weight: 1.02 :1 F-35A remains Power-to-Weight and Wing loading competitive against F-16C Block 52 up to about 800 Km combat radius. F-35A's 1407 Km combat radius is for combat transit range e.g. use Japan islands unsinkable aircraft carrier with more than enough range to strike at North Korea. ------ With body lift area. https://youtu.be/SsUCixAeZ0A?t=1038 F-14 designer (former Northrop Grumman VP Mike Ciminera) with body lift argument debunks Pierre Sprey's wing loading and wing size arguments. Most 4th gen fighters has body lift designs. https://s1.postimg.org/6xbltu4rj/Capture.png F-35A's real wing load i.e. colored green to blue are the lift surfaces. F-35A's real wing load i.e. colored green to blue are the lift surfaces. F-35's engine cowling generates lift that rivals wing lift hence easily duplicating F-18's long LEX or forward fix canards functions. Cant'ed twin tail adds additional rear lift. The oversize rear horizontal stabilizers has some lift and it's responsible for nose pitch (nose pointing). F-35A's effective lift area is about 620 sq ft. I have loaded F-35A's lift area into a CAD program and it yielded about 620 sq ft lift area with green-blue colored lift areas, minus horizontal stabilizers. With max 18,498 lb fuel load, F-35A has 75 lbs/ sq feet. With empty load, F-35A has 46 lbs/ sq feet. The real F-16 designer http://www.codeonemagazine.com/article.html?item_id=37 F-16 Designer Harry Hillaker Harry Hillaker's statement on low wing loading and wing size... We knew that we wanted low wing loading and high thrust loading. But we also knew that low wing loading means more weight and more drag Sprey's argument on wing loading and anti-small wings are not compete. Larger wings introduces higher drag . The trick with F-16's design is have medium wing loading, smallish wings and lower wing load during angle of attack turn with vortex lift. F-16 has blended wing design to get more lift from the body.

  41.  NSA BUM  Your narrative is false. YAK COPIED THE SAME DESIGNED FLAW AS CONVAIR MODEL 200!

The Pratt & Whitney 3BSD nozzle design predates the Russian work. In fact the 3BSD was tested with a real engine almost twenty years before the first flight of the Yak.

US government personnel were allowed to examine the aircraft. *However, the 3BSN design was already in place on the X-35 before these visits*. ------ YAK copied the same flawed two forward hot engine cores design from Convair Model 200. F--35 has shaft-driven cool air stream forward lift fan. https://history.nasa.gov/SP-468/ch10-4.htm During F-14 design phase, look at Figure 10. 11, notice NASA's concept design in regards to the engine and horizontal tail design and F-35's tail design. https://history.nasa.gov/SP-468/p256.jpg The above picture is one of many F-14 study models which is before Yak 141. https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19780008057.pdf https://crgis.ndc.nasa.gov/historic/File:L-74-2684.jpg Notice NASA's LFAX-8 concept design in regards to the engine and horizontal tail design which reappeared with F-35 The above picture is one of many F-15 study models which is before Yak 141. Since Lockheed Martin has taken over General Dynamics's Tactical Military Aircraft business Read http://www.aerospaceweb.org/question/planes/q0236.shtml General Dynamics has proto-YF-16 model with dual side engine intakes, single engine and dual angled tail with horizontal stabs extending beyond engine nozzle design. Both F-35 and proto-YF-16 with dual side intakes has blended body design which is different upper wing mounted design on the Yak 141 Using F-16's blended wing design, F-35 has upper bias blended wing design which is different from upper wing mounted design Yak 141 or MiG 25/31 which are similar to North American (Rockwell)'s A-5 Vigilante . I have Lockheed Martin's official viewpoint against YAK 41 copied fake news. YAK DID NOT SOLVE THE FUNDAMENTAL PROBLEM WITH CONVAIR MODEL 200 i.e. forward hot air stream being ingested by the main engine which reduces engine thrust! Copying the same flaws as CONVAIR MODEL 200 shows your brained dead copying.
