The McDonnell Douglas F-4X-VG was a design proposal to improve the carrier landing characteristics of the venerable F-4 Phamtom 2 in US Navy service. This eventually lost out to Grumman’s F-14 Tomcat but like the Tomcat the F-4X-VG has a variable geometry wing. The Navy passed on this proposal due to the VG-X’s apparent inablility to carry the AWG-9/AIM-54 Phoenix weapons system suite.
Since xbradtc blogged about this earlier in the week, I’m thowing up a cutaway for the latest incarnation of the western world’s (i.e. non-Russian) largest helicopter (that’d be helo to the NAVY/USMC team and “chopper” to the Army). This done is taken from the King Stallion’s website at Sikorsky:
The HAL Tejas is a 4+ generation single seat, single engine multirole fighter built primarily for the Indian Airforce and Navy. Slightly smaller than the F-16 the Tejas first flew on 4 January 2001 as the technology demonstrator called the LCA.
Here you can learn more about the Tejas.
Last week we did the Boeing Model 733 which evolved in to the Boeing 2707 (the 2 perhaps indicating that it was a mach 2 capable airplane). Anyway, this is a far better cutaway of the similiar aircraft AND it gives an indication of just how complex the actual airplane would have been.
The most recognizable difference between the 733 and the 2707 is the position of the variable geometry wing in relation to the horizontal stabilator. As you can see here, in full sweep, the is flush to the stab making it a delta shape simlar to the F-14 Tomcat. The 733 also features a variable geometry wing but at full sweep the aircraft resembles the B-1 Lancer in planform.
The Boeing Model 733 was the never-to-be-built US counterpart to the European Concorde and Soviet TU-144. Subsequent research is unclear whether the design started at a delta wing planform or started as a swing-wing that was eventually dropped due to increased weight and complexity.
