Title:
ELECTRIC TURBINE ENGINE AND ELECTRIC AIRCRAFT USING THE SAME
Document Type and Number:
Japanese Patent JP2022191117
Kind Code:
A
Abstract:
To achieve a high speed propulsion engine of an electric aircraft.SOLUTION: Two short ducts having the same diameter are connected by a beam, one turbine with one duct as a front duct or two turbines together with a second stage turbine are built in, a Sirocco fan having a length matched to the full length of the beam is installed at a beam part behind the turbine coaxially with the turbine, and compressed air from the front turbine and the Sirocco fan is merged and jetted from a nozzle of a rear duct end. One or more annular straightening blades of a short cylindrical shape are installed at an outer periphery of a beam part being a suction port of the Sirocco fan, air passing through an engine side part is drifted to an engine side, and air density of a suction surface of the Sirocco fan is increased to enhance intake efficiency. Also, this constitutes a VTOL high speed electric aircraft equipped with an engine mount having a displacement angle of 90 degrees or more at a left and right object position of a front end and a rear end of a blade.SELECTED DRAWING: Figure 2
