The proposed solution relates to a nozzle assembly for a combustor of an engine, having at least one nozzle for injecting hydrogen into a combustion chamber of the combustor, wherein the nozzle has a nozzle main body which extends along a nozzle longitudinal axis and a nozzle head at one end of the nozzle main body and comprises a first air conduit, a fuel duct for the hydrogen to be injected, and a second air conduit. The fuel duct is arranged with a fuel exit opening for the hydrogen to be injected into the combustion chamber between the first and second air conduits with their first and second air exit openings, in relation to a radial direction running perpendicularly to the nozzle longitudinal axis. Also according to the invention, at least the second air conduit, which is situated radially further outwards, is designed and provided to provide an non-swirled air flow into the combustion chamber and the fuel duct is designed and provided to provide a non-swirled flow of hydrogen into the combustion chamber.
