You can see in the illustration that this is a five-cylinder engine -- radial engines typically have anywhere from three to nine cylinders. The radial engine has the same sort of pistons, valves and spark plugs that any four-stroke engine has.
Radial Error Probability: A probability that a percentage of one-dimension measurements will lie on a radial (line) of given length, with the origin centered at truth or mean of the measurements; ...
Radial Engine
An engine design where the cylinders are designed symmetrically around a central crankshaft and hence radiate out.

radial - A magnetic bearing extending from a VOR/VORTAC navigation facility.
Radial: line from a VOR or NDB. For example, the 180 radial from a VOR represents a line south of that VOR.
RAF: Royal Air Force. Is also used as a prefix for a Royal Air Force base (for example: RAF Mildenhall)
RAS: Rectified Airspeed.
Radial engine - A reciprocating aircraft engine in which all of the cylinders are arranged radially, or spoke-like, around a small crankcase. Also referred to as round engines.
Radial Engine: An aero-engine with its cylinders arranged radially around the crankshaft, the cylinders being stationary and the crankshaft revolving.
RADIAL- A magnetic bearing extending from a VOR/VORTAC/TACAN navigation facility.
RADIO-
a. A device used for communication.
RADIAL ENGINE - One in which the cylinders are mounted equidistant and circumferentially around a circular crankcase. Cylinders and crankcase are fixed, and the crankshaft rotates.
...
Radial
RANGE
Two or more groups separated primarily separated in distance along the same bearing.
Aircraft Radial Tire: A pneumatic tire in which the ply cords extend to the beads and are laid substantially at 90 degrees to the centerline of the tire. Additional stabilization is provided by essentially inextensible belting in the tread area.
Instead of radials, bearings are used to describe your position to the NDB (or any other position). A bearing is measured clockwise from magnetic north and gives you the direction (or angle) between the aircraft and the NDB.
Descents in any radial present a challenge in that it's important to maintain reasonable oil temperatures. The 195 is especially susceptible in that the big wing resists descents, seducing you into major power reductions.
Set your OBS to radial 103, which you'll intercept and track to SFO (airport code, obviously, for San Francisco International).
This will set you up to execute a nice professional final approach.
11If the red-radial-line (as defined in the following section) is down near the bottom of the green arc, it is a good guess that wing stall is what limits the airplane's low-speed controllability.
The blade in such a design rotates in pitch about a bearing, aligned in a radial direction, which can be a roller bearing stack or a composite flexure.
Using a radial engine similar to that designed by Lawrence Hargrave in 1887, he built a power plant that weighed 208 pounds and produced an astonishing 52.4 horsepower.
The original (commercial production) 4-AT had three air cooled Wright radial engines. It carried a crew of three-pilot, co-pilot and stewardess-and eight or nine passengers. The later 5-AT had more powerful Pratt & Whitney engines.

(Hovercraft) Although not part of the conversion, it will be necessary to support the prop steel shaft on both ends with self-alining sealed ball bearings designed to absorb both the thrust and radial loads supported from engine mount forward and ...
In avionics, an aircraft might have an objective to fly to a radial of a radio station, then to fly along it. While en route, the objective is armed, meaning that the crew and software are attempting to reach the radial.

Vne - never-exceed speed, 'redline speed' denoted by a red radial on an ASI.
Vno - normal operating speed. The maximum structural cruising speed allowable f
or normal operating conditions (top of green arc on ASI).
COWL, COWLING - A circular, removable fairing around an aircraft engine (generally radial) for the purposes of streamling or cooling; aka RING COWLING.
COWL FLAP - A controllable louvre to regulating airflow through an engine's cowling.
COLLECTOR RING - A circular duct on a radial engine into which exhaust gases from its cylinders are safely discharged.
Federal Airway Routes - Also known as Victor (V) routes, this airspace (below FL 180) established in the form of a corridor, the center line of which is defined by particular radials off radio navigational aids.
DME Fix: A geographical position determined by reference to a navigational aid which provides distance and azimuth information as defined by a specified distance in nautical miles and a radial in degrees magnetic from that aid.
The United Aircraft Corporation began work on the fighter, the Vought Corsair in 1938. The designer, Tex B. Beisel, used the most powerful engine available, the 2,000 hp Pratt & Witney X-R2800 Double Wasp 18-cylinder radial.
The aircraft's position is displayed as a function of its magnetic bearing "to" or "from" the VOR station. Pilots can then track toward or away from the station while monitoring their course along that individual VOR radial.
As a mechanic he has worked on planes from as small as 152's up to C-97's, DC-3's, C-130's and a couple other big radial and turbine airplanes that are used as firebombers. Brendan is 28 years old and works at Velocity Inc. in Sebastian, Florida.
