The first flight of the E-Fan 2.0 was originally planned for 2017 and the E-Fan 4.0 for 2019. [1] A ducted fan on the E-Fan. The E-fan is of all-composite construction and is propelled by two ducted, variable-pitch fans spun by two electric motors totaling 60 kW of power. Ducting increases thrust while reducing noise, and having the fans ...
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 ...
Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h (200mph). Most cooling fans used in computers contain a duct integrated into the fan assembly; the duct is also used for mechanically mounting the fan to other components. The Martin Jetpack personal aircraft with ducted fans
Electric Flight - Don Belfort reported on the latest in electric flight. Vintage Views - This was a look at the history of the hobby with Bob Noll. R/C Acrobatics - In this column, Dave Lockhart explored the world of radio controlled acrobatic flight. Fan Facts - Greg Moore reported on the emerging world of ducted-fan model airplanes.
Each power unit comprises a Wankel rotary engine directly driving a ducted fan. [7] [8] The housing is lined with Kevlar to contain the fan blades in the event of failure. [7] The Skycar has four such nacelles, each with two Rotapower engines mounted in tandem. All eight engines operate independently under computer control and, as demonstrated ...
Many notable individuals in the 1960s through the 1990s and beyond created the landscape of modern RC modeling. These included many starting their own companies. The families of many of these individuals lost interest in continuing these businesses. The incoming supply of ARF planes from overseas made it hard to sell kits requiring assembly.
By May 2018 almost 100 electric aircraft were known to be under development. [5] This was up from 70 the previous year and included 60% from startups, 32% from aerospace incumbents, half of them major OEMs and 8% from academic, government organizations and non-aerospace companies, mainly from Europe (45%) and the U.S. (40%). [6]
Compared to an unducted propeller, a ducted fan generates more thrust for the same area and speeds of up to 200 mph (320 km/h) have been recorded with electric-powered ducted fan airplanes, largely due to the higher RPMs possible with ducted fan propellers. Ducted fans are popular with scale models of jet aircraft, where they mimic the ...
