Trouble on Triton is not to be confused with the 1941 Henry Kuttner novel or the 1954 Alan E. Nourse novel Trouble on Titan. The title of the novel was inspired by Leonard Bernstein's 1952 opera, Trouble in Tahiti. Fred Pohl, the editor at Bantam, made Delany shorten the title to Triton to avoid confusion. [6]
A simple 3 blade toroidal propeller. A toroidal propeller is a type of propeller that is ring-shaped with each blade forming a closed loop. The propellers are significantly quieter at audible frequency ranges, between 20 Hz and 20 kHz, while generating comparable thrust to traditional propellers.
Single-blade propeller drawing Single-blade propeller and glider drawing. A single-blade propeller may be used on aircraft to generate thrust.Normally propellers are multi-blades but the simplicity of a single-blade propeller fits well on motorized gliders, because it permits the design of a smaller aperture of the glider fuselage for retraction of the power plant.

Hartzell Propeller is an American manufacturer that was founded in 1917 by Robert N. Hartzell as the Hartzell Walnut Propeller Company. [1] It produces composite and aluminum propellers for certified , homebuilt , and ultralight aircraft.
The essence of the actuator-disc theory is that if the slip is defined as the ratio of fluid velocity increase through the disc to vehicle velocity, the Froude efficiency is equal to 1/(slip + 1). [2] Thus a lightly loaded propeller with a large swept area can have a high Froude efficiency.
A trimotor is a propeller-driven aircraft powered by three internal combustion engines, characteristically one on the nose and one on each wing. A compromise between complexity and safety, such a configuration was typically a result of the limited power of the engines available to the designer.
The P.24 Monarch was a 24-cylinder development of the H-16 layout version of the Prince, designed by chief engine designer Captain A.G. Forsyth. [2] Similar in layout to the Napier Dagger, the cylinders were arranged vertically in two blocks, driving contra-rotating propellers using separate shafts and gears.
