Abstract
When an aircraft is propelled by at least one jet engine fixed in a rear part of the aircraft, at least one substantially horizontal rear aerodynamic surface, the rear horizontal surface, is arranged at the rear of the aircraft and at least one jet engine is fixed under the rear horizontal surface by an attachment mast fixed by its upper part to the rear horizontal surface and maintains, by its lower part, the jet engine. The rear horizontal surface is also the horizontal tail unit of the aircraft or a horizontal surface maintained above the fuselage. The rear surfaces and the fuselage are arranged such that the engines are installed and removed using a vertical movement of the engines, which are advantageously one, two or three in number, in the rear zone of the aircraft.
Claims26
An aircraft comprising:
- a fuselage having front and rear portions;
- a wing connected to the fuselage;
- and
- a rear tail unit situated behind the wing at the rear of the aircraft, said rear tail unit having at least one horizontal stablilizer;
- at least one jet engine fixed to the at least one horizontal stabilizer of the rear tail unit and located under the horizontal stabilizer by means of an attachment mast disposed between the horizontal stabilizer and the at least one jet engine;
- said attachment mast and said horizontal stabilizer being arranged such that said at least one engine hangs vertically adjacent to said fuselage and substantially proximal to the ground, or hangs vertically above a non structural part of said fuselage and substantially proximal to the top to the fuselage, thereby allowing easy installation and/or removal of said engine.
