B-52 Re-engine program

The iconic Cold-war era Boeing B-52H Stratofortress bomber is getting its 1960s-vintage Pratt & Whitney TF33-103 engines replaced by more-efficient commercial replacements. The re-engine program will keep the colossal aircraft operational until 2050 and meet the high-power demands for next-generation weapons, a fire control radar, and other electrical systems. The B-52 is the most combat capable bomber in the U.S. inventory with...

Revival of Voyager 1 after 37 years

The backup thrusters on the Voyager 1 spacecraft fired up after staggering 37 years. It took 19h and 35 min through space for the signal to reach an antenna in Goldstone, California, US, which is a part of NASA’s Deep Space Network. Voyager 1 was launched by NASA on September 5, 1977, 16 days after its twin, Voyager 2. Both these spacecraft are a part of the Voyager program to study the outer Solar System. On August 25, 2012, Voyager...

Airbus Pushes Towards High-Speed Compound Helicopter

Helicopters are fantastic. They can easily access remote areas, and are capable of vertical takeoff and landing. However, what they seem to be lacking is speed when in forward flight. A few aerospace companies have taken to combining the VTOL capabilities of rotary aircraft, with the the forward speed that turboprop airplanes offer. Although there are many challenges, one of the biggest is keeping the price down . Three years after...
