Ducted Fan RC Jet - Working and History

  The first ducted fan Jet experiments were performed in 1998. The launch of these experiments provided the knowledge and expertise to build and design improved ducts and fans. The year of 1999 witnessed the first test flights combined with an enhanced duct and fan combination. The induction of the technology of duct fans showed that duct fan jets have the capability to reach top speeds at high RPM due to attached thin blades and a tapered blade chord.


In the past, "unducted" fan engines were also tested. The jet had fewer blades and it was greater in diameter size than the common ducted fan jet. However, "unducted" fan jets were bogged down because of their noise issues. In case of a ducted fan jet, the fans are used to contain the noise of the jet engine, thus providing a pleasant flying experience. Neither of these can be provided by an "unducted" fan engine. Also there was a risk involved in flying "unducted" fan engines because they can cause damage to the blades being fewer in number.


EDF RC jets are one of the types of remote control jets for you to choose form. These types of jets provide the experience and thrills of flying without any complexities and are most cost effective. The jet has a built-in duct fan that allows the jet to reach speeds of 20,000 RPM and even more.


Most ducted RC jets are supplied with a bladed fan engine offering huge RPM that boosts the speed of the jet. The ducted fan is a very minimal in size but it is a part of a powerful unit. The ducted fan consists of a propeller which is multi-bladed and spins at a very high speed, thus generating the thrust to reach maximum levels.


As the impeller spins at a high speed, the air is sucked through the impeller and forced out through the small funnel-shaped fan unit which generates a lot of thrust for the jet to catch speed. The ducted fan acts as a cooling system for the jet due to its strong capability to fly at huge speeds. These ducts are designed to fit in the engine of the jet at a relatively lower cost. The ducts can be used for both the electric and gas engines of the RC jet.


Flying RC toy airplanes has become a rather popular and enjoyable hobby that transcends people of all ages. The ability to make a small scale model of an airplane always fascinates the hobbyists and the onlookers alike in such a way that a magical moment seems to envelop the crowd whenever the RC toy is aloft. Most of the flying RC toys you have seen might have been propeller driven but there is one type right now that is taking the RC world by storm. These are the newer jet powered flying RC toys that uses ducted fans or gas turbines instead of propellers.


Perhaps the cheapest varieties in the market today are the electric fan types. These particular jet engines use electricity stored in rechargeable batteries to turn the ducted fan attached to the aircraft. However, you may wonder how does electric ducted fan powered RC toys really work. What are ducted fans anyway?


To begin understanding how electric ducted fans enable the plane to fly, one has to first understand what ducted fans are. These are a type of propulsion arrangement through which a scaled down propeller is encased within a barrel-shaped shroud or duct. The function of the duct is to reduce the losses in thrust power while increasing the pressure and velocity of the airflow.


That kind fun fan in flying RC toys is an amalgamation of different parts arranged in such a way that it gives the airplane the power to take off into the air. These consist of the front housing flange, rotor cone, the fan rotor which acts as the impeller, ducted fan housing, motor, aft cone, and stator extension.


The front housing flange and rotor cone maintain the smoothness of the airflow as it goes inside the assembly. Doing so amplifies the effectiveness of the ducted fan assembly. The fan rotor, or impeller, then pushes the air through the whole assembly while the fan enclosure holds and regulates the airflow. This is why the shape of this enclosure is very important to achieve maximum efficiency of the fan.


The electric motor in the middle powers the fan rotor or impeller. This motor is connected to the batteries and RF board to enable the transmitter to control its RPM. The function of the aft cone is to lessen, if not eradicate, the turbulence which is usually caused by the airflow https://hongguanfan.shop/. The stator also decreases the turbulence caused by the rotation of the impeller blades and straightens the air flow as it passes through the whole assembly.


Electric ducted fan powered RC toys are gradually gaining popularity among hobbyists because, aside from being stylish, it also reduces the risk of propellers being broken as a result of a bad landing. This type of RC flying toy is suitable for beginners because of the simplicity of its control array which is sometimes comparable to simple propeller driven RC toys.

Guerrilla Marketing With Unconventional Results

  When someone sets out to open a traditional brick and mortar store, it can be pretty obvious what marketing strategies will need to be used to get customers talking about and shopping in the store. When you own an online business that doesn't have a physical destination, it can be a little trickier deciding between all the different ways you can market it to your target audience. If you are a new and fairly small internet based company, the chances are that your available time and budget are probably pretty small as well, which doesn't leave a lot of clear direction for how you should go about marketing yourself. If you feel creative and really want to generate some interest about your product or service, you should definitely consider guerrilla marketing as one of your strategies. If you're not familiar with the term guerrilla marketing, then you should know that it simply refers to a method of orchestrating unusual promotional tactics that cost you more in time and inno
