A gas turbine engine for an aircraft. The gas turbine comprises a combustor, a fuel injection system connected with a source of fuel and configured to inject fuel into the combustor, a water injection system connected with a source of water and which is configured to inject water into the combustor, and a control system. The control system is configured to identify an atmospheric condition; determine a water-fuel ratio for injection into the combustor of the gas turbine engine in response to the atmospheric condition; and control injection of fuel and water by the fuel injection system and the water injection system according to said water-fuel ratio to control an soot emissions caused by combustion of fuel therein.

The inventions applicable to industrial gas turbines at power plant to minimize nitrogen oxides from gas turbine exhaust and maximizing gas turbine efficiency done by replacing the standard air filter system by oxygen filtration system (O) to allow oxygen only and substituting the nitrogen by high-pressure water HPW injected in compressor (C) last stages only. The one unit of oxygen to be injected by 4 units of HPW, since air contains 5 units 4 units of nitrogen and 1 unit of oxygen, the 5 units of oxygen are to be injected by 20 units of HPW required for the process. A heat exchanger to be installed at gas turbine exhaust duct to heat the HPW injected into compressor (C) last stages, which is to be mixed with HPW at ambient/atmospheric temperature to cool compressor air outlet temperature to targeted temperature as shown in FIG. 1. A control system is essential to control the process.

Provided is a method for enabling high-density air to be efficiently manufactured without unnecessarily increasing the pressure and temperature. A method for manufacturing high-density air according to the present invention includes: mixing raw air A with fine water particles W to generate water-containing air A1 having a lower pressure than the raw air A; supplementing the water-containing air A1 with a differential pressure between the pressure of the raw air A and the pressure of the water-containing air A1; and consequently promoting vaporization of the fine water particles W in the water-containing air A1 and reducing the volume of the water-containing air A1 to manufacture high-density air A2. The density of air can be efficiently increased with this method.
