NOVELTY - The combustor has a set of circumferentially spaced fuel nozzles (3) and pure air/premixed fuel-air nozzles (4) aligned on planes that are normal to longitudinal direction, where the nozzles in the different planes have same fuel/air ratio or varying fuel/air ratio. An outer shell/liner (1) is made of high temperature alloy or ceramic material. A front wall liner connects the outer shell/liner and an inner shell/liner (2), and comprises a hole or nozzle that allows compressor discharge air or pure air (6) to penetrate the outer shell/liner at velocity magnitude less than the nozzles.    USE - Annular shaped tangential and flameless combustor for an aero gas turbine engine that is utilized for producing propulsion or rotation of a shaft for power generation such as ground based power generation, land or sea based vehicle, and aircraft engine application (all claimed) such as military and commercial aircraft application.    ADVANTAGE - The combustor is designed such that more uniform temperature distribution is achieved at a combustor' s outlet which allows for the combustor to operate at higher combustion temperatures by optimal mixing of fuel and air for combustion without deteriorating life of the combustor and turbine parts so as to increase engine efficiency and power output while reducing carbon dioxide emission levels, thus reducing need for costly pollution control devices and piloting issues, and hence enhancing ignition and flame stability and improving vibration reduction. The combustor is designed such that required residence time to combust fuel-air mixture is reduced, so that combustion space is reduced, thus decreasing engine size and weight to thrust ratio.
