Design Specification 2

Hybrid flight mode: a mode when additional ascentional force is created by lifting aircraft power plants, which is calculated taking into account the factor of their negative impact on the ascentional force created by the flying wing surface. Therefore, it is important to figure out their optimal attachment position.

Example of airflow distribution in hybrid flight mode

✍️Calculations: Aerodynamics

1. Carry out an aerodynamic calculation of a 3D model of a flying wing in a hybrid flight mode

   • Attack angle, α: 0;

   • Location of the lifting screws rotation plane: 0 , +40, +20, -20 mm relative to fuselage centerline

   • speed, V: 70 km/h.

2. Define parameters as follows:

   • Ascensional force (general and distributed across the aircraft elements), kg;

   • Resistance (general and distributed across the aircraft elements), kg;

   • Wing/drag ratio.

3. Fill out the chart below

   
4. Specify the modeling environment used.
