Then in the 1930s it all changed. Aerodynamicist John Stack sketched out his idea for a purpose-built, full-scale research aircraft capable of reaching Mach 1, the speed of sound. Ten years later Stack and a small group of engineers worked to turn this idea into a design for an actual ...
If there is a problem with the plane, the crew must keep the passengers calm and help them exit the aircraft if necessary. Attendants must also be prepared to deal with terrorists, irate passengers and various medical emergencies. In situations where most people would be paralyzed with panic, ...
To find out more about how has the price of gas changed throughout the years, Stacker ran the numbers on the cost of a gallon of gasoline for each of the last 84 years. Usingdata from the Bureau of Labor Statistics(released in April 2020), we analyzed the average price for a gallon ...
For example, if the elevators are pointing up and the paper is strong enough, the momentum created will force the back of the airplane down, causing the nose to pitch up. Note that while this is not an official aerodynamic explanation, it can become a general rule of thumb for students ...
Chuck a stone off the side of a mountain and it will plummet as well. Sure, steel ships can float and even very heavy airplanes can fly, but to achieve flight, you have to exploit the four basic aerodynamic forces: lift, weight, thrust and drag. You can think of them as four arms ...
If you find yourself on a flight that has yet to be upgraded (E175 and select 737 aircraft), you’ll still have Gogo ATG4 basic inflight internet that does the job for checking emails, social media, and a bit of browsing. However, select 737-9 MAX aircraft and all Q400 aircraft used...
The Piaggio Avanti is renowned for its unique three-lifting-surface configuration, which contributes to its exceptional aerodynamic efficiency. However, noise is an issue when it comes to this aircraft type.The interior of the cabin offers a level of quietness that allows for conversations, due to...
The rotor hub cap (above the rotors) helps to reduce aerodynamic drag. There are two turbo-shaft jet engines, one on either side of the rotors. If one engine fails, there should still be enough power from the other engine to land the helicopter safely. Photo: An engineer repairs the ama...
They were highly aerodynamic, a benefit that was referenced in the car’s name. The car was extremely revolutionary at the time and was a big shift from the non-aerodynamic cars back then, which encountered a lot of wind resistance. Alamy Stock Photo by Chuck Eckert The ...
Multirotor: This term can be used to describe any aircraft that has multiple rotors. Octocopter: A UAV that has eight motors/propellers. Quadcopter: A UAV that has four motors/propellers. Tricopter: A UAV that has three motors/propellers. Propulsion ESC: Stands for “Electronic Speed Controlle...
