✈DRAGON LADY🚀

The Lockheed U-2, nicknamed "Dragon Lady", is an American single-jet engine, ultra-high altitude reconnaissance aircraft operated by the United States Air Force and previously flown by the Central Intelligence Agency. It provides day and night, high-altitude, all-weather intelligence gathering.This aircraft is introduced during the cold War between American and Russia to be able to detect the Russian hide and seek!

Top speed: 805 km/h
Introduced: 1957
Wingspan: 31 m
Range: 960 km
Engine type: General Electric F118

👁‍DO YOU KNOW WHY HIGH WINGS ARE MOSTLY USED IN RECONNAISSANCE /CARGO AIRCRAFTS?

✅Due to lower aspect ratio it produces more induced drag. More induced drag means higher co-efficient lift that make the reconnaissance aircraft can go up to 70,000ft.

Reasons:

1⃣.The horizontal tail area of an aircraft with a high wing is about 20% larger than the horizontal tail area with low wing. 

✈more downwash of a high wing on the tail

✈structurally about 20% heavier than low wing but can reduces when struts are employed. The struts can withstand the tensile stress which gives the aircraft lighter.

2⃣.High wing will increase dihedral effect 

🛫It makes the aircraft laterally more stable

🛫The aircraft lateral control is weaker compared with mid-wing and low-wing, since the aircraft has more laterally dynamic stability.
Eg. Antonov An-22

3⃣.Producing more induced drag(di) due to higher lift co-efficient(Induced drag=C²L/pi.e.AR)
🛩Produce more lift compare with mid and low wing.

4⃣.During take-off and landing operations, the ground will influence the wing pressure distribution
✈The wing lift will be slightly lower than the low wing configuration
✈The aircraft will stall speed since CLmax will be higher.

5⃣Eases and facilitates the loading and u loading of loads and cargo into and out of cargo aircraft.
✈facilitates the taking off and leading from the sea.
