3. Preamble to the description:
Complete Specification:
Summary:
In this invention, aircraft engines are designed to with brushless DC motors made up of unique formulation of neodymium doped with nano particles of samarium, lanthanum or any other similar type of rare earth elements. In the summary of invention, each important salient feature is explained as follows:
• propeller is connected to a unidirectional positive displacement system which is coupled with a driven gear
• that gear is driven by a dual side rack
• that rack is connected to a screw rod which gives displacement
• screw rod is displaced using a BLDC motor with magnets made of Samarium and lanthanum nano particles
• similar system is used when screw rod displaced in opposite direction

4. Description
An aircraft engine is the component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines.
In this invention, Aircraft engines are designed based on the principles of mechanical advantage system. Special aero dynamic veins are used as propeller blades and engine is designed with brushless DC motors made up of rare earth magnets. In this aircrafts design payloads ranging from 30 kg to 500 kg are possible. These engines are run by either rechargeable batteries or gas or methanol based fuels. These aircrafts can be remotely operated for unmanned operations in the areas like agriculture aerial spraying, aqua feed distribution and cargo applications.
Background of invention
Most aircraft engines use spark ignition, generally using gasoline as a fuel. All aviation fuel is produced to stringent quality standards to avoid fuel-related engine failures. Aviation standards are much stricter than those for road vehicle fuel because an aircraft engine must meet a strictly defined level of performance under known conditions. These high standards mean that aviation fuel costs much more than fuel used for road vehicles. This results in higher fuel cost.
