Antonov An 990 !!install!! -

The Antonov An-990 is a freeware mod created by a flight simulation developer known as hangglider on the X-Plane.org Forums . It was built to test the extreme boundaries of physics, weight, and scale within a flight simulator.

The most distinguishing feature of the An-990 concept was its proposed or "flying wing" configuration. While most cargo aircraft are essentially flying tubes (fuselages) with wings attached, the An-990 aimed to integrate the cargo hold within a thick, aerodynamically shaped wing structure. antonov an 990

Pilots must find massive runways with over 500 feet of side clearance to account for the immense wingspan. The Antonov An-990 is a freeware mod created

Reaches a ceiling of 32,100 ft even at maximum load. While most cargo aircraft are essentially flying tubes

(13.2 million lbs), it is approximately 120 times heavier than a standard Boeing 737-100 Powerplant

According to aviation lore, the An-990 performed high-speed taxi tests in 1983. The propfan engines, however, proved problematic. The acoustic resonance generated by the experimental blades caused severe structural vibration, threatening to tear the airframe apart.
