Abstract

A gas turbine engine comprises an electrically heated hot air chamber 1 for heating air. Ideally the air is heated once it has been compressed by the compressor. The hot air chamber preferably comprises banks of electrically heated elements 5 mounted in parallel, and which span the length of the chamber 1. The resistance heaters expand the air in the chamber causing it to drive the turbine, which in turn drives the compressor. Air is able to flow through the chamber from the front to the rear. Air-flow powered alternators may provide the electricity required to sustain the electrical heating system, and are ideally located between the compressor and the heating chamber. The hot air chamber could is preferably made from heat retaining material. The spool transmission shafts may be located through a tunnel 6 in the chamber. Allegedly, no fossil fuel is required by the engine.

Description

--2444784
DESCRIPTION
ELECTRICALLY HEATED HOT AIR CI-IAMBER FOR (JSE IN TURBINE ENGINES This invention, by design, produces a very high temperature airflow for use in a turbine that produces forward thrust to propel aircraft. It is a self contained unit within an outer body, as is consistent with gas turbines (more commonly known as jet engines).
The hot air chamber consists of an outer casing made from heat retaining material. Housed within this chamber, which can be of any geometric design, there are banks of electrically heated elements spaced close together but with the ability to allow pressurised air to pass them.
Mounted between the compressor and the heat chamber are the air flow propelled alternators which produce the electricity needed to power the electric heaters encased in the heat chamber.
This unit does not use fossil fuels allowing the vehicle its propelling to be as much as one third lighter in weight and it does not omit dangerous carbon.

Claims (6)

- CLAIMS
1) It is claimed that the electrically heated hot air chamber (hereafter known as EHAC) consists of a lightweight box chamber made from heat retaining material.
2) The EHAC and all other component parts will be housed inside the outer engine covers, similar to a conventional turbine.
3) Within the chamber of the E1-IAC are banks of electrically heated elements mounted parallel to each other and running the full length of the chamber.
4) Mounted externally from the EHAC chamber wifl be an appropriate number of air flow powered alternators producing the required amount of electricity needed to sustain the heat system at both low and high capacity.
5) A central, rotating shaft passes through a tunnel in the EHAC linking the fan and compressor at the front of the engine to the turbine mounted at the rear.
6) Forward motion of the vehicle is achieved by the exhaust of high pressure hot air through a nozzle at the rear.
