It’sFleet Weekhere in San Francisco and that think of Navy Flight Demonstration Squadron aka The Blue Angels are back in town for the festivity . This is what it have to change over a battle - quick F / A-18 Hornet into a howling stunt - fly Angel .
The Blue Angels flight exposition squad was formed in 1946 by order of Admiral Chester Nimitz so as to boost esprit de corps and march the Navy ’s fighting art ( and gain public favor to counteract a shrinking budget ) . The original team flew modified Grumman F6F-5 Hellcats and has flown a total of nine aircraft in the 65 age since . The F / A-18 Hornet is the late to be employed by the squad and has been in service since 1986 when it replaced the A-4 Skyhawk .
The Hornets in the Blue Angel Squad have been significantly modified from those that see active scrap . In addition to an extra inverted fuel pump allowing for longer invert flight of steps without the railway locomotive becoming fuel - famish and a high - color , miserable - rubbing paint to dilute drag , the M61 Vulcan machine gun in the nose cone has been replace with a armored combat vehicle that take hold the jet ’s supply of smoke oil .
The coloured smoking that the special K produce is made by injecting a biodegradable paraffin - found oil into the plane ’s exhaust nozzles , immediately vaporise it . It not only grant spectators to follow along more easily , these smoke trails increase each pilot ’s visibility to the rest of the squad .
The Blue Angels planes also treat differently from the armed combat fashion model thanks to the installation of a small spring on the command stick that put on 40 pounds of olfactory organ - down pressure — stimulate the aeroplane easier to pilot in formation and upside - down while increasing the reefer ’s sensitivity . However , that also means the pilot must continually overcome that added pressure sensation to maintain a level flight path .
In addition , because of blank space restriction in the cockpit the Blue Angels pilots do n’t wearG - suits , whose never-ending inflating and puncture zephyr bladder would step in with command the plane . However , since the flight are coordinated , the pilots live when high G maneuvers are coming up and can execute the same job manually by clenching their stomach and leg muscles to prevent rip from rushing from their head to their low bodies , causing them to black out .
And while they are n’t engagement - ready per se , they can be transition back to engagement - ready position ( repainted and rearmed ) within 72 hr were the pauperization to arise .
The biggest difference between a Hornet and an Angel is not what they ’re equip with but what they run on . hornet get the traditional jet fuel but the Angels fly the coop on a 50 - 50 mix of plant - based bio - fuels and ceremonious fuel , making it the first and only full Navy squadron to vanish with biofuels .
The US war machine is in reality the single largest energy consumer in the rural area with petroleum providing 80 % of that necessary but has aggressively developing alternatives — as well they should given that a $ 1 increase in the price of a cask of oil translates into a $ 30 million zip price increase for the Navy alone . Between 2006 and 2009 , the Pentagon tripled its spending on alternate energy from $ 400 million to $ 1.2 billion .
