What is Drag?

Drag, aerodynamic Resistance, is the force exerted by the air on a rocket as it moves through the atmosphere, pushing it backwards. This force negatively affects the rocket’s speed and altitude. Drag can be categorized into two types: aerodynamic drag and pressure drag. Aerodynamic drag occurs as air flows around the rocket, creating friction and turbulence. Pressure drag, on the other hand, results from differences in air pressure caused by the rocket’s nose.

The magnitude of drag is proportional to the square of the rocket’s velocity and the density of the air. To minimize drag and optimize rocket performance, careful attention is given to rocket design and flight planning. Drag reduces rocket speed and altitude, can compromise stability, make parachute deployment difficult, and alter the rocket’s landing point.


Factors Contributing to Drag and Methods to Minimize Drag

Telemetry systems are essential components of modern technology designed to facilitate remote data collection and monitoring processes. These systems enable data collection from remote locations, supporting various applications such as fieldwork, space missions, and industrial operations. Real-time data monitoring enables rapid and effective decision-making processes. Telemetry systems enhance efficiency across industries and facilitate more effective management of operational processes.

Another significant advantage of telemetry systems is the ability to analyze collected data and perform necessary actions. By interpreting collected data, these systems evaluate and optimize system performance. Additionally, data analysis plays a critical role in identifying potential issues within systems and developing preventive maintenance strategies. Telemetry systems enhance operational efficiency, reliability, and durability across industries.
