The Boeing B-17G Flying Fortress “Texas Raiders” of the Commemorative Air Force starts its engines at Warbirds Over Dallas this past October. Note the ground crew ready with the fire extinguishers.⁣ ⁣ Note the slots on the wing just behind the engine nacelles- they’re the exhaust slots from the intercooler of the Flying Fortress’s turbosupercharger. ⁣ ⁣ The turbosupercharger is driven by exhaust gases from the radial engines- the turbine of the turbosupercharger compresses incoming air and delivers it to the engine, improving the engine’s power output at high altitude as it’s being fed compressed air as if it were operating at a lower altitude. ⁣ ⁣ However, one of the thermodynamic consequences of compressing the air is that it heats up and this can decrease the air density, offsetting the very compression you’re trying to accomplish. Intercoolers are used in turbosuperchargers reduce the air temperature and can also increase the pressure of compression by virtue of the flow restriction by the internal fins in the intercooler. ⁣ ⁣ If you look at the leading edges of the B-17’s wing, there are rectangular openings which are the intakes for incoming air that’s compressed by the turbosuperchargers and another intake that’s for the cooling air that flows through the intercooler. The exhaust air from the intercoolers is vented out through those slots on the top of the B-17’s wing.⁣ ⁣ #Avgeek #aviation #aircraft #planeporn #KRBD #RBD #airport #planespotting #WingsOverDallas2021⁣ ⁣ #Boeing #B17 #FlyingFortress #instagramaviation #igaviationcontest #mil_aviation_originals #USAAF #instaaviation ⁣#TexasRaiders #CommemorativeAirForce⁣ ⁣ #AvGeeksAero #AvGeekNation #AvgeekSchoolofKnowledge #TeamAvGeek (at Dallas Executive Airport) https://www.instagram.com/p/CW94SSbsVkf/?utm_medium=tumblr

I caught this moment at the conclusion of the Royal Canadian Air Force's Snowbirds demonstration at the Fort Worth Alliance Air Show last year- Snowbird 2, Captain Sarah Dallaire, jumps up and high fives the only female ground crew chief on the team, Corporal Victoria Carpenter. ⠀ ⠀ ⠀ The team leader, Snowbird 1, is Major Denis Bandet and he's the bald one in the red flight suit.⠀ ⠀ ⠀ Captain Dallaire is from Quebec and both of her parents were general aviation pilots who flew for leisure. When she was 12 years old, she met the first female Snowbirds pilot, Maryse Carmichael, and that's when Dallaire set her sights on becoming an RCAF pilot. ⠀ ⠀ ⠀ Touchingly, when Dallaire was selected to join the Snowbirds, it was Carmichael who pinned her wings.⠀ ⠀ ⠀ November Aviation Photo Challenge | @kjdphoto1971 | #1119planes | “Ladies Day” | Day 16⠀ #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #Canadair #CT114 #Tutor #instagramaviation #igaviationcontest #mil_aviation_originals #RCAF #Snowbirds #instaaviation #aviationlovers #aviationphotography #flight #aviationphotography #AvgeekSchoolofKnowledge #AvGeeksAero #AvGeekNation (at Fort Worth Alliance Airport) https://www.instagram.com/p/B47gDgmBXJ4/?igshid=jifaun0bhe53

While the P-51 was the first aircraft to be designed with a laminar flow wing, in reality the wing never demonstrated laminar flow despite what’s often said in aviation literature. Yes, laboratory and wind tunnel studies did demonstrate laminar flow- but small manufacturing imperfections, camouflage paint, dirt, and dings from operational use pretty much prevented laminar flow from taking place. A laminar flow airfoil has other benefits beyond laminar flow and this is where the Mustang got its advantage. Because the thickest part of the airfoil is further back from the leading edge, compressibility and shockwave formation is delayed- this feature is beneficial even at lower speeds as it reduces drag and while laminar flow would have been great, the delay in compressibility and shockwave formation in practice was a more significant factor to give the Mustang outstanding performance. #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #NorthAmerican #P51 #Mustang #instagramaviation #igaviationcontest #Avgeekery #mil_aviation_originals #USAAF #instaaviation #AvGeeksAero #AvGeekNation #AvgeekSchoolofKnowledge https://www.instagram.com/sentinelchicken/p/Bw3Fq_JlWa2/?igshid=h54h72uq790a

The Royal Canadian Air Force Snowbirds don't fly the fastest and loudest jet with their Canadair CT-114 Tutor trainers, but they fly a big formation gracefully this "diamond nine" formation pass. The CT-114 Tutor first flew in 1960 and was the primary jet trainer for the RCAF from 1964-1999. The Snowbird story really begins with the RCAF Golden Hawks which were established in 1959 to celebrate the 35th anniversary of the RCAF and the Golden 50th anniversary of powered flight in Canada. Flying Canadair-built F-86 Sabres, the team flew 317 displays over 5 seasons before being disbanded due to budget cuts in 1964. But the popularity of the Golden Hawks didn’t fade. In 1967, CT-114 Tutors were used for a new RCAF display team called Golden Centennaires for the Centennial of Canadian nationhood. The team only flew 100 displays for the 1967 air show season before being disbanded. The Centennaires rekindled the public’s desire for a permanent display team. In 1971 a new unofficial demonstration team was formed at the Canadian Forces Flight Training School at CFB Moose Jaw, Saskatchewan by the Centennaires’ former commander, with the name "Snowbirds" selected in 1972. The team operated on a shoestring budget until 1977 when they were officially designated the Canadian Forces Air Demonstration Team. In the 1978, the Snowbirds attained full squadron status as 431 Air Demonstration Squadron with the full backing of the Department of National Defence. In 1999, the Snowbirds received the Queen’s Colors in recognition of 25 years of active display service. They continue to use the CT-114 to this day despite its phase out for regular RCAF flight training. #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #Canadair #CT114 #Tutor #instagramaviation #igaviationcontest #Avgeekery #mil_aviation_originals #RCAF #Snowbirds #instaaviation #AvgeekSchoolofKnowledge (at Fort Worth Alliance Airport) https://www.instagram.com/p/Bs3RyvGFET3/?utm_source=ig_tumblr_share&igshid=ewlxge811suf

Thunderbird 5 pulls hard into a climb with the powerful vortices from the LERX (leading edge root extensions) on each side of the forward fuselage creating a significant condensation cloud in the humid air this afternoon. Those powerful vortices energize the air moving over the wings, giving the F-16 its legendary maneuverability. The LERX created the vortices which on this humid day are nicely delineated by the condensation clouds streaming back from either side of the cockpit. The LERX acts as a giant vortex-generating strake in what is called “controlled vortex lift”- the vortex is always there- it does three things for the F-16- the vortex energizes the airflow over wing, allowing a smaller wing to create the same amount of lift as a larger wing without the vortex (for the F-16 this came out to about a 500 lb savings), secondly, it improves the directional stability, particularly at high angles of attack (this makes the F-16 very maneuverable) and finally, it also reduced trim drag which improves range or payload for a given mission profile. #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #Lockheed #F16 #FightingFalcon #instagramaviation #igaviationcontest #Avgeekery #mil_aviation_originals #USAF #Thunderbirds #instaaviation #AvgeekSchoolofKnowledge https://www.instagram.com/p/Bpk_hFaFnUa/?utm_source=ig_tumblr_share&igshid=jj4bfqcg5tln

The Cavanaugh Flight Museum's P-51D Mustang "Brat III" gets airborne at the 2018 Fort Worth Alliance Air Show. Did you know the Dallas/Fort Worth area is the second largest cluster of aerospace workers in the world, topped only by Southern California? North Texas’s importance to the aerospace industry has its roots in the Second World War and the P-51 Mustang was part of that contribution. At the outbreak of war, the P-51 Mustang was being built at North American Aviation’s Inglewood, California, facility, but a second, more inland factory was needed (there were still worries at the time about attacks on US coastal targets)- North American built a plant in Grand Prairie at what become NAS Dallas in later years. In terms of interior volume, the North American Dallas plant was the largest aircraft plant of the Second World War and it was built in only 120 days. At the peak of Mustang production which ran 24 hour a day to support the war effort, eight P-51s A DAY were rolling out of the Grand Prairie factory and they were being produced faster than the US Army Air Forces could accept them! Almost 1/3 of the total P-51 production of 15,586 was built in Dallas. In fact, every single one of the P-51C variant was built in North Texas. North American’s AT-6 Texan trainer was also built here- in fact, 83% of the AT-6 production came from Dallas. At the peak of wartime production, over 40,000 workers staffed the facility- no other employer in the history of the DFW area has employed more people than North American Aviation during the Second World War, even to this day (the current largest employer being American Airlines with approximately 25,000 employees in the area). #Avgeek #aviation #aircraft #planeporn #KAFW #AFW #AllianceAirport #FWAAS2018 #AllianceAirShow2018 #airport #planespotting #NorthAmerican #P51 #Mustang #instagramaviation #igaviationcontest #Avgeekery #mil_aviation_originals #USAAF #instaaviation #CavanaughFlightMuseum #AvgeekSchoolofKnowledge (at Fort Worth Alliance Airport) https://www.instagram.com/p/BplAFgWFVo0/?utm_source=ig_tumblr_share&igshid=6va8n25a06j6

N9002U, American’s second A319 factory delivered with winglets, is just seconds from touchdown on 18R at DFW. In fact, if you look close, you can see the runway numbers reflected on the nose. Both the CFM56-5B turbofan of the Airbus A320 family and CFM56-7B of the Boeing 737NG family share a common core; where they differ is the diameter of the fan- the -7B used on the 737NG is just a -5B with a smaller fan, but differences in the fan blade aerodynamics and engine software offset what could have been a less economical engine due to its smaller fan. The fan on the -7B is 60.5 inches in diameter to fit the underwing 737 nacelle but the taller landing gear of the A319/320/321 means the -5B gets a 68.3 inch fan. There are some differences in the core, but many core parts are interchangeable between the two CFM56 variants used on the two rival aircraft families. #avgeek #aviation #aircraft #planeporn #KDFW #DFW #airport #igTexas #planespotting #airlines #megaplane #instaplane #Airbus #A319 #American #AmericanAirlines #DFWavgeek #instagramaviation #avgeekery #igaviationcontest #N9002U #AvgeekSchoolofKnowledge #instaaviation #aviationlovers #aviationphotography #flight #splendid_transport (at Dallas Fort Worth International Airport) https://www.instagram.com/p/BqnvAA-lhs5/?utm_source=ig_tumblr_share&igshid=1lmz8mc00l6h0
