Abstract

Řešení se týká výroby leteckých motorů a jeho účelem je zvýšení konstrukční spolehlivosti. Tohoto účelu se dosáhne tím, že prstencová spalovací komora motoru s plynovou turbinou je opatřena tělesem, ve kterém je umístěn plamenec s proudnicovým krytem a vstupní mezikruhový difuzor s vnitřním a vnějším pláštěm ze kterých vnější plaší je spojen s tělesem svým předním koncem a je pevně spojen prostřednictvím meziprvkú s proudnicovým krytem svým zadním koncem podle směru proudění, přičemž meziprvky jsou tvořeny plochými silovými žebry umístěnými podél proudění.The solution concerns the production of aircraft engines and its purpose is to increase the design reliability. This purpose is achieved by having annular gas engine combustion chamber the turbine is provided with a body in which there is a flame bar with a streamline cover and an input annular diffuser with an internal and the outer shell of which the outer shy is connected to the body by its front end and is firmly connected through intermediate element with streamline cover with its rear end in the direction of flow, the intermediate elements being flat force ribs located along the flow.
