Cowling
A specially shaped nose to enclose an engine.
See also: Engine Cowling.
Cowling. A metal cover enclosing the whole or part of the power unit of an aero engine.
Cracked Spirit. The fuel obtained by high temperature distillation of crude oil. Petrol of high octane value is prepared by this process.
RING COWLING - A circular engine FAIRING.
ROGALLO WING - A flexible, delta-wing plan in which three rigid members are shaped in the form of an arrowhead and joined by a flexible fabric, which inflates upward under flight loads.
COWL, COWLING - A removable FAIRING around an aircraft engine for the purposes of streamling or cooling.
COWL FLAP - A controllable louver to regulating airflow through an engine's COWLING.
Cowling
The aerodynamic covering for the engine.
Tail Rotor Driveshaft
Provides power to the tail rotor from the transmission.
COWLING - The name of the fairing which, usually, encloses an engine.
CYCLIC PITCH CONTROL - Means of changing the pitch of a rotor's blades progressively, to provide a horizontal thrust component for flight in any horizontal direction.
COWLING
A removable metal covering placed over and around an airplane`s engine (s)).

Look inside cowling for small animals, lost wrenches, oil leaks, etc.
Inspect the nose wheel and fairing. The nose wheel strut and tire should be properly inflated.
At the top of the cowling area you will see the static source. This measures the static pressure inside the helicopter fuselage. The static system is connected to the Altimeter, VSI, and Airspeed indicator.
A sight mark on the cowling has the advantage that it is farther away from your eye, so it is easier to keep both it and the horizon in focus at the same time.

When those terminals are exposed to a temperature range of as low as 0 degrees or lower in the winter to 180 degrees under the cowling or behind the panel in summer, that metal expands and contracts with the temperature.
If you can remove the top cowling, then do so. At least once a day before the first flight. I cannot count the times I lifted 'the hood' and found something loose.
Examples include the engine cowlings, antennas, and the aerodynamic shape of other components.
Interference Drag comes from the intersection of airstreams that creates eddy currents, turbulence or restricts smooth airflows.
Rather than chasing the airspeed indicator, position the nose of the airplane (top of the engine cowling) just above the horizon and hold it there. Notice how the airspeed needle has quit moving up and down and has stabilized on one speed.
Aerodynamically, Bass augmented the Robertson STOL kit with a LoPresti Speed Merchant package that modernizes and improves the cowling nose bowls, installs a one-piece windshield and introduces a variety of lesser improvements.
Parasite drag includes the landing gear, antennas, cowlings, doors, etc. The shape of the fuselage will also produce parasite drag.
Fuselage, booms, nacelles, cowlings, fairings, airfoil surfaces (including rotors but excluding propellers and rotating airfoils of engines), and landing gear of an aircraft and their accessories and controls.
Another sore spot is the oil access panel. The sleek lines of the fiberglass cowling are interrupted by the awkward metal access panel, which does not conform well to the more rounded shape of the upper half of the cowling.
The engine had a wide cowling, which enclosed one 0.50 in machine gun and one 0.30 in machine gun. Armament was completely inadequate when compared to the contemporary Hawker Hurricane, and the Messerschmitt Bf 109.
It includes the form drag and skin friction associated with the fuselage, cockpit, engine cowlings, rotor hub, landing gear, and tail boom to mention a few. Parasite drag increases with airspeed.
