The Northrop Grumman E-10 MC2A was planned as a multi-role military aircraft to replace the Boeing 707-based E-3 Sentry and E-8 Joint STARS, the Boeing 747-based E-4B, and the RC-135 Rivet Joint aircraft in US service. The E-10 was based on the Boeing 767-400ER commercial airplane. In 2003, the Northrop Grumman, Boeing, and Raytheon MC2A team ...
In the world of model aircraft there are several competition classes to signify engine displacement. Class Cubic Inches Cubic Centimeters
The aircraft was to provide a survivable platform to conduct war operations in the event of a nuclear attack. Early in the E-4's service, the media dubbed the aircraft as "the doomsday planes". [6] The E-4 was also capable of operating the "Looking Glass" missions of the Strategic Air Command (SAC). [14]
The E-4B "Nightwatch" is nicknamed the "doomsday plane" because it can survive a nuclear attack. In the event of nuclear war, it would serve as the US military's command and control center.
The Air Force currently operates four E-4B aircraft with at least one on alert at all times. The fleet of highly-modified Boeing 747-200 jumbo jets has become increasingly difficult and expensive ...
This statement seems to strongly suggest that the Air Force will once again turn to the Boeing 747, the only US-made four-engine airliner built in the several years prior, and the only aircraft based on a four-engine airliner platform built in the US since the last new-build E-3 Sentry and E-6 Mercury aircraft, both based on the Boeing 707 ...
Four-stroke model engines have been made in sizes as small as 0.20 in3 (3.3 cc) for the smallest single-cylinder models, all the way up to 3.05 in3 (50 cc) for the largest size for single-cylinder units, with twin- and multi-cylinder engines on the market being as small as 10 cc for opposed-cylinder twins, while going somewhat larger in size ...
The reduced size affects the model's Reynolds number, which determines how the air reacts when flowing past the model, and compared to a full sized aircraft the size of control surfaces needed, the stability and the effectiveness of specific airfoil sections may differ considerably requiring changes to the design.
