Glow plug engines combined with ducted-fan units were the first achievable means of modeling a scaled-size jet aircraft. Despite the introduction of model-scale turbojet engines, electric-powered ducted fans remain popular on smaller, lower-cost model aircraft. Some electric-powered ducted fan airplanes can reach speeds of more than 320km/h ...
Pamaypay for sale in Iriga City, Philippines Yellow antique abaniko. Pamaypay (Tagalog pronunciation: [pɐmaɪˈpaɪ], puh-my-PY), also known as paypay, payupas, buri fan, or anahaw fan, [1] [2] [3] is a type of traditional hand-held fan from the Philippines.

The fans were generally powered by 2 stroke engines at high RPM. They generally had 0.40 to 0.90 cu in (6.6 to 14.7 cc) displacements, but some were as small as 0.049 cu in (0.80 cc). This fan-in-tube design has been adopted successfully for electric-powered jets while glow engine powered ducted-fan aircraft are now rare.
In the 1960s, Hanno Fischer, Technical Director of Rhein-Flugzeugbau (RFB), developed an interest in aircraft powered by ducted fans integrated into the aircraft structure, flying two modified gliders as testbeds, a VFW-Fokker FK-3 fitted with an eight-bladed ducted fan in the rear fuselage, which flew as the Sirius I in 1969, and a Caproni Vizzola Calif A-21, which flew as the Sirius II on 16 ...
A household electric fan A large cylindrical fan. A fan is a powered machine that creates airflow. A fan consists of rotating vanes or blades, generally made of wood, plastic, or metal, which act on the air. The rotating assembly of blades and hub is known as an impeller, rotor, or runner. Usually, it is contained within some form of housing ...

KDK International Philippines Corp. (KIPCO) was founded in November 1979 as a joint venture company between Avenue Electrical Supply and Matsushita Seiko Co. Ltd, for the purpose of importing, distributing and selling all KDK products in the Philippine market such as electric fans, ventilating fans and other air moving equipment.
The glow plugs used in model engines are significantly different from those used in full-size diesel engines. In full-size engines, the glow plug is used only for starting. In model engines, the glow plug is an integral part of the ignition system because of the catalytic effect of the platinum wire. The glow plug is a durable, mostly platinum ...
