A radio-controlled aircraft (often called RC aircraft or RC plane) is a small flying machine that is radio controlled by an operator on the ground using a hand-held radio transmitter. The transmitter continuously communicates with a receiver within the craft that sends signals to servomechanisms (servos) which move the control surfaces based on ...

The impact factor relates to a specific time period; it is possible to calculate it for any desired period. For example, the JCR also includes a five-year impact factor, which is calculated by dividing the number of citations to the journal in a given year by the number of articles published in that journal in the previous five years.

Consequently, physically smaller and lighter power supplies can be used with these so-called micro-scale actuators. Investigations demonstrated that per actuator, induced velocities from the micro-scale plasma actuator are comparable to their standard, macro-scale counterparts, albeit with an order of magnitude less thrust.

The Langley Aerodrome is a pioneering but unsuccessful manned, tandem wing-configuration powered flying machine, designed at the close of the 19th century by Smithsonian Institution Secretary Samuel Langley. The U.S. Army paid $50,000 for the project in 1898 after Langley's successful flights with small-scale unmanned models two years earlier. [1]
The Cessna 172 Skyhawk is the most produced aircraft in history.. An aircraft (pl.: aircraft) is a vehicle that is able to fly by gaining support from the air.It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, [1] or, in a few cases, direct downward thrust from its engines.
Cancer Immunology Research is a monthly peer-reviewed medical journal published by the American Association for Cancer Research. It covers research and clinical trials related to the study of cancer immunology. The editors-in-chief are Robert D. Schreiber and Philip Greenberg. [1] The journal was established in 2013. [1]
