Description This is the latest edition - fully revised and updated - of the standard textbook on aerodynamic theory, as applied to model flight. Everything is explained in a concise and practical form for those enthusiasts who appreciate that a better understanding of model behaviour is the sure path to greater success and enjoyment, whether just for fun or in competition. The revisions for this new edition reflect the significant developments in model aircraft during the last few years, and include brand new data: Product details Format Paperback pages Dimensions x x His more advanced book Model Aircraft Aerodynamics is the standard work on its subject in the English language.
Model Flight is a much simplified introduction to the same complex field. Rating details. These might consist of forming a frame using thin planks of a light wood such as balsa to duplicate the formers , longerons , spars , and ribs of a vintage full-size aircraft, or, on larger usually powered models where weight is less of a factor, sheets of wood, expanded polystyrene , and wood veneers may be employed.
Regardless of the underlying structure, it is then skinned and subsequently doped to provide a smooth sealed surface. For light models, tissue paper is used. After it is applied, the paper is sprayed with a mist of water, which causes the paper to shrink when it dries.
For larger models usually powered and radio controlled heat-curing or heat shrink covering plastic films or heat-shrinkable synthetic fabrics are applied to the model then heated using a hand held hair dryer, laundry iron or heat gun to tighten the material and adhere to the frame.
Microfilm covering is used for the very lightest models and is made by bringing a wire loop up through water to pick up a thin plastic film on the surface made from a few drops of lacquer spread out over several square feet.
Flying model of S. For a more mass market approach, "foamies," or aircraft injection-molded from lightweight foam sometimes reinforced have made indoor flight more accessible to hobbyists.
Many require little more than attachment of the wing and landing gear. Flying models can be assembled from kits, built from plans or made completely from scratch.
A kit contains the necessary raw material, typically die- or laser-cut wood parts, some molded parts, plans, assembly instructions and has usually been tested. Plans are intended for the more experienced modeller, since the builder must make or find all the parts themselves. Scratch builders may draw their own plans, and source all the materials themselves.
Any method may be labour-intensive, depending on the model in question. To increase the hobby's accessibility to the inexperienced, vendors of model aircraft have introduced Almost Ready to Fly ARF designs which reduce the time and skills required. A typical ARF aircraft can be built in under 4 hours, versus 10—20 or more for a traditional kit.
Ready To Fly RTF radio control aircraft are also available, however among traditionalists, RTF models are controversial as many consider model building integral to the hobby.
Gliders[ edit ] Gliders do not have an attached powerplant.
Larger outdoor model gliders are usually radio-controlled gliders and hand-winched against the wind by a line attached to a hook under the fuselage with a ring, so that the line will drop when the model is overhead.
Other methods include catapult-launching, using an elastic bungee cord. The newer "discus" style of wingtip hand-launching has largely supplanted the earlier "javelin" type of launch.
Also using ground-based power winches, hand-towing, and towing aloft using a second powered aircraft. Gliders sustain flight through exploitation of the wind in the environment. A hill or slope will often produce updrafts of air which will sustain the flight of a glider.
This is called slope soaring , and when piloted skillfully, radio controlled gliders can remain airborne for as long as the updraft remains. Another means of attaining height in a glider is exploitation of thermals , which are columns of warm rising air created by differences of temperature on the ground such as between an asphalt parking lot and a lake. Heated air rises, carrying the glider with it.

As with a powered aircraft, lift is obtained by the action of the wings as the aircraft moves through the air, but in a glider, height is only gained by flying through air that is rising faster than the aircraft is sinking relative to the airflow.
Sailplanes are flown using thermal lift. As thermals can only be indirectly observed through the reaction of the aircraft to the invisible rising air currents, skill is required to find and stay in the thermals. Hang gliders are composed of rigid frame from which the fabric skin is attached, much like a triangular sailboat sail.
The payload and crew are suspended or hung from the frame, and control is exercised through the movement of the harness in opposition to a control frame, Paragliders use a special type of steerable parachute for a wing.

Control is exercised through lines that deform the trailing edge of the airfoil or the wing's end regions. Walkalong gliders are lightweight model airplanes flown in the ridge lift produced by the pilot following in close proximity. In other words, the glider is slope soaring in the updraft of the moving pilot see also Controllable slope soaring. Power sources[ edit ] Powered models contain an onboard powerplant, a mechanism powering propulsion of the aircraft through the air.
Electric motors and internal combustion engines are the most common propulsion systems, but other types include rocket , small turbine , pulsejet , compressed gas, and tension-loaded twisted rubber band devices. It is the most widely used powerplant for model aircraft, found on everything from children's toys to serious competition models.CO2, like rubber, is known as "cold" power because it becomes cooler when running, rather than hotter as combustion engines and batteries do.

Regardless of the underlying structure, it is then skinned and subsequently doped to provide a smooth sealed surface. Class 'D' 60 size speed planes can easily reach speeds well in excess of MPH.
A hill or slope will often produce updrafts of air which will sustain the flight of a glider. The Cleveland Model and Supply Corporation made the most complex, challenging kits, while Guillow's made simpler, relatively easy kits.
