• Aviation, Semester 2, position 5

Introducing students to the complex movement of aircraft in atmospheric flight. During the course will be studied the performance of the aircraft, i.e. will be studying the movement of the aircraft’s center of gravity under the action of forces. Within the Course Term Project Assignment, that covers and integrates the entire course material, students will be able to obtain performance of the aircraft, individually with the use of modern software packages, such as Matlab, Mathcad, Excel, etc.

Mastering the course, the student acquires enough theoretical knowledge to be able individually and creatively to define performance capabilities of modern aircraft and all restrictions that result from them. In this course, students will gain full sublimation and verification of previously acquired knowledge and skills they have acquired within the Aeronautical module from the group of aerodynamic courses.

Introduction. General assumptions in the calculation of the aircraft performance. Coordinate systems and coordinate transformation. Types of movement. The forces acting on the aircraft during the flight. Performance of the aircraft powerplants. Propellers. Geometric and aerodynamic characteristics of the propellers. Selection of the propeller. The equations of motion of aircraft. Basic aircraft performance. Basic flight performance (horizontal and vertical speed, time of the climbing, theoretical and practical flight ceiling). Special aircraft performance. Take off and landing. The effect of wind on the flight performance. Range and endurance, radius of action. The effect of wind on the range and radius of action. Unsteady movement in the vertical plane. Dive and pulling out of a dive. Aircraft maneuvers. Dynamic flight ceiling. Loop. Immelman. Roll. Pugachev's Cobra. Bell. Herbst maneuver. Optimization of the flight path of the aircraft. Spatial movement of aircraft. Introduction to the mechanics of cosmic flight.
