FlightGear started as an online proposal in 1996 by David Murr, living in the United States. He was dissatisfied with proprietary, available, simulators like the Microsoft Flight Simulator, citing motivations of companies not aligning with the simulators' players ("simmers"), and proposed a new flight simulator developed by volunteers over the Internet.
Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. [4] [5] Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear.
The construction system Meccano is a popular tool for constructing highly accurate orreries. Model 391, the first Meccano Orrery, was described in the June 1918 Meccano Manual. [29] [30] In Dune Messiah, the 1969 sequel to Dune, there is a description of a desktop orrery representing the two moons of the fictional planet Arrakis and its sun.
SpaceEngine is an interactive 3D planetarium and astronomy software [2] initially developed by Russian astronomer and programmer Vladimir Romanyuk. [3] Development is now continued by Cosmographic Software, an American company founded by Romanyuk and the SpaceEngine Team in February 2022, based in Connecticut.
Add-ons illustrating less well-known internet fiction, like Orion's Arm, or role-playing games, like 2300 AD, and personal works by members of the Celestia community depicting fictional planetary systems with inhabited worlds, spacecraft, cities, and special effects can also be added. An example of a user-made fictional planetary system in Celestia
The Ravigneaux gearset is a double planetary gear set, invented by Pol Ravigneaux, who filed a patent application on July 28, 1949, in Neuilly-sur-Seine France. [1] This planetary gear set, commonly used in automatic transmissions, is constructed from two gear pairs, ring–planet and planet–planet. The gearset provides four forward gear ...
Notice that the sun and flywheel rotate twice for every circuit of the planet when they have a 1:1 ratio of teeth. The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine. With the ...
Outerra is a Slovak computer software company best known for its middleware 3D planetary graphics engine, called Outerra engine, in development since 2008. [2] The engine renders high-quality terrain, terrain texturing, flora and water flow normal maps using relatively sparse and highly compressed data through fractal processing and other types of procedural generation.
