Squawking 7700 in the big wide world of aviation. From my own aviation art and photography to all the little vectors I follow to interesting aviation history......
If there’s no exhaust spike sticking out of the hot section back on the MD-11’s engine, then you’re looking at the Pratt & Whitney PW4000 series engine, the successor to the JT9D. There are three variant families to the PW4000, this is the smallest with a 94-inch fan and is also used on the A300 freighters of UPS. The next size up is the 100-inch fan used on the A330 and the biggest is the 112-inch fan used on the 777. Note the British Airways 747-400 on final approach. #Avgeek #aviation #aircraft #planeporn #kdfw #dfw #airport #planespotting #airlines #ups #mcdonnelldouglas #md11 #instagramaviation #avgeekery #megaplane #instaplane #N284UP #igaviationcontest #avgeekery #avgeekschoolofknowledge #instaspotting #boeing #747 #britishairways  (at DFW Founders Plaza)

When the King Air C90 launched in 1971, it was the first major performance upgrade to the iconic King Air line since it’s start in the early 1960s- with more powerful PT6A engine versions, a longer span wing and a host of other upgrades, the C90 was a brisk seller for Beechcraft even though it wasn’t the fastest turboprop twin on the market- 550 C90s were built before upgraded C90 variants replaced it in production. I believe the C90 family alone has totalled over 1000 and is still in production today as the C90GTi which began deliveries in 2008. #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #airport #igtexas #planespotting #beechcraft #kingair #kingairnation #C90 #megaplane #instaplane #instadfw #instagramaviation #avgeekschoolofknowledge #avgeekery #instaspotting #igaviationcontest (at Addison Airport)

N798UA decelerates on 19C at Dulles. Eight Boeing 777-200s in United’s fleet have been passed on to other airlines, I think they were leased 777s- a mix of -200ERs and non-ER 200s went to Air India and Varig before Varig went tango uniform. N798UA here is a -200ER delivered to United in February 1998. #Avgeek #aviation #aircraft #planeporn #KIAD #IAD #dulles #airport #planespotting #airlines #megaplane #instaplane #boeing #United #777 #instagramaviation #N798UA #igaviationcontest #avgeekery #avgeekschoolofknowledge

No real commentary this time. Just playing with my man toys.

When the Douglas Skyraider was still named the BT2D Dauntless II, the chief designer, Ed Heinemann, figured out that for every 100 lbs saved translated to an additional 22 miles of range and an additional 18 feet/minute in climb rate. He had his team look for weight savings in the BT2D, no matter how small. Over 1800 lbs was removed in an impressive effort- using a tail wheel at a time when a nose wheel was the future is one example of such design changes (no nose wheel weight), along with elimination of the bomb bay it was to have. There are only recesses in the lower wing for the extension/retraction linkages and the wheel- no true landing gear well- when retracted, the landing gear leg lays outside of the wing’ slower surface. The weight saved gave the Skyraider tremendous payload capacity and an impressive loiter time over the battlefield jets could only dream of possessing.  #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #warbirdsoveraddison #airport #igtexas #planespotting #megaplane #instaplane #instagramaviation #douglas #ad #a1 #skyraider #igaviationcontest #avgeekschoolofknowledge #avgeekery (at Addison Airport)

As aircraft engines get quieter, noise from other airframe components caused by air rushing past has taken on a greater proportion of aircraft noise compared to the past with older jet engine technology. The nose gear in particular is a significant contributor to airframe noise due to its location. Back in May Gulfstream filed a patent for a modified nose gear to reduce airframe noise. This was based on research by Gulfstream, NASA, and the University of Florida to localize the specific noise sources on the nose gear- it was found the single biggest contributor to airframe noise from the nose gear was from the torque link that runs diagonally aft from the nose gear leg. So Gulfstream’s patent moves the component to the front ahead of the nose gear leg and by shaping it right , it can smooth the airflow around the nose gear strut; smoother flowing air is more quiet. Another fairing would be added between the nose wheels to smooth the airflow there as well. #Avgeek #aviation #aircraft #planeporn #KIAD #IAD #dulles #airport #planespotting #airlines #megaplane #instaplane #boeing #Gulfstream #G400 #GIV #instagramaviation #N400MP #igaviationcontest #avgeekery #avgeekschoolofknowledge

N401WN rolls by on Taxiway E at Houston Hobby for departure off 12R. Delivered to Southwest on March 2001, 401 is at an odd corner of HOU where the ends of three runways are practically on top of each other- 12R, 12L, and 17.  #Avgeek #aviation #aircraft #planeporn #KHOU #HOU #houston #hobbyairport #airport  #igtexas #planespotting #airlines #boeing #737 #southwest  #instagramaviation #avgeekery #N401WN #swapic

A Cessna Citation III pops open the spoilers after landing at Addison. The Citation III was a quantum leap for Cessna in the early 1980s as it moved into larger and faster jet designs that were a departure from its initial Citation bizjet offerings which were really more competitors to turboprop twins. Being a clean sheet design with a need for speed, Cessna turned to NASA aerodynamicist Richard Whitcomb with the result that the Citation III became the first American production aircraft to use Whitcomb’s supercritical wing. At one point Cessna very seriously considered powering the Citation III with three engines which, combined with the supercritical wing would have been a real rocketship, but that had to wait for the Citation X and the Citation III settled on two engines. When delivered to its first customers in 1983, the Citation III set several speed and altitude records for its class. In many ways, the Citation III set the stage for the high performance Citation X. #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #airport #igtexas #planespotting #Cessna #Citation650 #CitationIII #N125RH #megaplane #instaplane #instadfw #instagramaviation #avgeekschoolofknowledge #avgeekery #instaspotting #igaviationcontest (at Addison Airport)

If you look really close at this Dassault Falcon 900, just above and ahead of the first passenger window you can see a flat array satcom antenna- this is the HGA-48A phased array satcom antenna made by Thales Avionics-  it’s basically a conformal array that offers low drag and the 24-element antenna attaches to the outside fuselage with two antennas, one in each side 45 degrees from straight horizontal. I didn’t realize that these were available on bizjets, I’d seen similar conformal arrays mostly on military aircraft and some jetliners. #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #airport #igtexas #planespotting #dassault #falcon900 #N908CA #megaplane #instaplane #instadfw #instagramaviation #avgeekschoolofknowledge #avgeekery #instaspotting #igaviationcontest (at Addison Airport)
