The paper considers relevance of the problem of vortex formation between the air inlet edges of a low-mounted turbofan engine and analyzes consequences of this phenomenon affecting the aircraft operation. It uses the example of the trunk-root aircraft low-mounted turbofan engine to consider the vortex formation process exposed to the lateral airflow influence. Dependence of the vortex formation intensity on the lateral airflow speed is revealed. A method is proposed to determine the vortex formation intensity between the airfield surface and the air inlet edge. The need to develop design and operational methods in protecting the aircraft low-mounted engines from foreign objects is noted. Initial data for development of the design and operational methods to protect the engine from foreign objects are determined.
