1. Illustration of Pushquito flying at noon under the sun, viewed directly from below it.
Push quadcopter is different from conventional quadcopter because a vertical propeller at the rear-end of its fuselage is used for pushing the quadcopter forward. The other 3 propellers which are at horizontal plane, are used to provide lift as in conventional quadcopter. Varying the speed of the side propellers controls roll, while varying the speed of the front-end propeller controls pitch, and synchronizing the speed of the 3 horizontal propellers control yaw. As such, the configuration of push quadcopter allows for better aerodynamic (because only 1 propeller is located at the front-end) and greater thrust (because the thrust is provided by a vertical plane propeller) than in conventional quadcopter, allowing push quadcopter to fly faster than conventional quadcopter.
"Pushquito" is the 1st conceptual design of push quadcopter. It is a 2-door 4-seat GT (gran turismo) quadcopter, meaning it is suitable to travel a significant distance in a significant speed with comfort for 4 people.
2. Top view of Pushquito.
"Pushquito" is a word coined by me, carrying a meaning, "the first push quadcopter and a small one", as the word "Push" describes the thrust provided by a push propeller, "q" represents quadcopter, "quito" represents "1" as the numerical value of quito in Chaldean and Pythagorean numerology is "1", and "Pushquito" sounds similar to "mosquito", a small flying insect.
3. Side view of Pushquito: The contra-rotating propellers are visible in the bottom illustration.
The thrust of Pushquito is provided by a single vertical contra rotating propeller, each with twin blades. The lift is provided by 3 contra rotating horizontal propellers. All the propellers are ducted for better safety. The position of the front-end propeller is low enough to provide an unobstructive forward view to the pilot and the passengers. A single front propeller is an advantage in the design of push quadcopter compared to the twin front propeller as required in the design of conventional quadcopter.
4. Top view of Pushquito: Notice the low profile front horizontal propeller duct.
5. Bottom view of Pushquito with the propellers rotating.
Of course a push quadcopter may have twin push propellers or other type of propulsion including turbofan for greater thrust. In this case, the push units are considered as a unit of propulsion so that such aircraft can still be categorized as push quadcopter.
