Primary Flight Instruments

Primary flight instruments provide essential information about an aircraft’s motion, orientation, altitude, speed, and climb/descent. They are fundamental to flight mechanics, pilot decision-making, and aircraft control.

The primary components of an aircraft include the fuselage (body), wings (which produce lift), tail assembly (responsible for stability), powerplant (engine, which generates thrust), and landing gear (for ground support), all managed from the cockpit through flight control surfaces such as ail...

Lighter-than-air (Aerostats)

Lighter-than-air systems are the flight systems deriving a significant amount of their lift from the buoyancy effects related to lighter than air gases like hydrogen, helium and methane. Contrary to fixed-wing aircrafts LTA systems are associated with minuscule fuel consu...

Wind Tunnel Testing

Incompressible flow assumption

Applications: Lift, drag, flow visualization, UAVs, automobiles, buildings

Compressibility effects begin

Applications: Aircraft wings, airfoils, control surfaces

Compressible Flow

Before using the calculator, ensure availability of the following parameters:

Temperature, T (Kelvin, K)
Pressure, p (Pascal, Pa)
Velocity, V (meters per second, m/s)
Gas Constant, R (J/kg·K)
Ratio of Specific Heats, γ
After calculation, the following outputs will be displayed:
1. Density (ρ...

Airfoil & Wing

Geometric Angle of Attack (α): The angle between the chord line and the common reference line (often the horizontal axis of the aircraft).

Induced Angle of Attack (α_i): The angle by which the local airflow is deflected (downwash) compared to the free-stream velocity.

Basic Fluid Mechanics

As I went on, still gaining velocity, the palpitation of night and day merged into one continuous greyness; the sky took on a wonderful deepness of blue, a splendid luminous color like that of early ...

Data Collection: This is the foundational step. It involves defining the mission requirements (e.g., payload, flight duration, range, operating environment, size constraints) and gathering component data (e.g., motor specifications, battery energy density, propeller performance curves) that will dri...

Classification of UAV

UAVs can be classified according to the type of wing and aerodynamic configuration they use. The wing configuration significantly influences the UAV’s stability, endurance, maneuverability, payload capacity, and mission role.

Atmosphere

Understanding the atmosphere is essential for safe and efficient flight, as atmospheric properties directly influence aircraft performance, control, aerodynamic behavior, and the accuracy of flight instruments.
