Control Surfaces Located on the Aircraft Wing
Certain conditions must be met in order for the aircraft to remain in the air and for this to continue in a stable manner. In order to stay in the air, airplanes need a lift force equal to their total weight and in the opposite direction. Airplanes produce this lift force thanks to their wings,…
What is Mesh Structure

What Is Solar Cycle ?
The solar cycle, also known as the sun’s magnetic activity cycle, is a periodic change that occurs every 11 years, determined by the amount of change in the number of sunspots observed on the sun’s surface. In this cycle, the times when the sunspots are the least are called the solar minimum, and the times…
Why Does The White Smokes Come Out When Space Shuttles Are Launched?
If you’ve ever seen a rocket launch, perhaps a similar question came to your mind at that time: What is this cloud of white smoke that comes out as the rocket takes off, how and why does it form? First of all, it should be noted that during the firing of these gigantic space shuttles…

Brief Introduction to CFD Analysis
As science began to classify the natural dynamics and related reactions of air, water, or gas, the physics of fluid dynamics continued to develop. This provides a system structure with rules of thumb and is derived from the idea of flow measurement to solve practical problems. Typical fluid dynamics problems involve basic fluid properties related…
What Is Jet Engines And How Does It Works
A jet engine is a machine that converts energy, rich liquid fuel into a powerful thrust called thrust. The thrust of one or more engines pushes the aircraft forward, forcing the air through its scientifically shaped wings, creating an upward force called “lift” that pushes it toward the sky. One way to understand modern jet…
Starship SN15 Rocket Flew and Landed Successfully
On Wednesday, May 5, Starship serial number 15 (SN15) successfully completed the fifth high-altitude flight test of a Starship prototype from SpaceX’s Starbase in Texas. Since rocket parts have very expensive parts, being able to recover their parts as much as possible has been an issue that has been discussed by scientists. These rescue systems,…
Big Step in Search of Life on Mars
The spacecraft Perseverance of the American National Aeronautics and Space Administration (NASA) completed its seven-month journey and successfully landed on Mars on 18.02.2021. The vehicle will search for traces of past life during its stay on the Red Planet. The data obtained by Perseverance, which can obtain microscopic images thanks to the equipment on it,…
Boeing Will Ship New Solar Panels to the International Space Station
The International Space Station, which has pulled most of its electricity from eight large solar panels for the past 15 years, will be powered by six new solar panels. The new add-on will provide a 20 to 30 percent increase in total power and will enable the complex’s growing research capabilities and commercial opportunities. Boeing…
The Importance of Composites in the Aerospace and Astronautical Engineering
Materials science is of paramount importance to any industry. One of the most costly material research and investment areas is the space and aviation industry. Composite materials used in aviation are at the forefront as materials that give the best results in terms of strength / lightness. Looking at the aircraft and space industry, it…
Automobile Aerodynamics
Aerodynamics, in its most basic definition, is the study of how gases interact with moving bodies. Since air is the most common gas we encounter, aerodynamics is primarily concerned with drag and lift forces caused by air passing over and around solid objects. Engineers apply aerodynamic principles to the designs of many different things, including…
A Brief Introduction to Rocket Aerodynamics
The concept of aerodynamics is mainly the study of how air flows over and through objects, as well as the effects of forces generated by air flows. Therefore, a rocket flying in the air is necessarily subjected to aerodynamic forces, and therefore rockets must be designed in accordance with these conditions. The external design of…
