Some of the Elements of Aerospace Engineering

"The fact that the great scientist believed in flying machines was the one thing that encouraged us to begin our studies." 
~Wright Bersaudara, Penemu Pesawat Terbang~




  • Astrodynamics – the study of orbital mechanics including prediction of orbital elements when given a select few variables. While few schools in the United States teach this at the undergraduate level, several have graduate programs covering this topic (usually in conjunction with the Physics department of said college or university).

  • Statics and Dynamics (engineering mechanics) – the study of movement, forces, moments in mechanical systems.




  • Control engineering – the study of mathematical modeling of the dynamic behavior of systems and designing them, usually using feedback signals, so that their dynamic behavior is desirable (stable, without large excursions, with minimum error). This applies to the dynamic behavior of aircraft, spacecraft, propulsion systems, and subsystems that exist on aerospace vehicles.

  • Aircraft structures – design of the physical configuration of the craft to withstand the forces encountered during flight. Aerospace engineering aims to keep structures lightweight.

  • Materials science – related to structures, aerospace engineering also studies the materials of which the aerospace structures are to be built. New materials with very specific properties are invented, or existing ones are modified to improve their performance.

  • Solid mechanics – Closely related to material science is solid mechanics which deals with stress and strain analysis of the components of the vehicle. Nowadays there are several Finite Element programs such as MSC Patran/Nastran which aid engineers in the analytical process.

  • Aeroelasticity – the interaction of aerodynamic forces and structural flexibility, potentially causing flutter, divergence, etc.

  • Avionics – the design and programming of computer systems on board an aircraft or spacecraft and the simulation of systems.

  • Software – the specification, design, development, test, and implementation of computer software for aerospace applications, including flight software, ground control software, test & evaluation software, etc.

  • Risk and reliability – the study of risk and reliability assessment techniques and the mathematics involved in the quantitative methods.

  • Noise control – the study of the mechanics of sound transfer.

  • Flight test – designing and executing flight test programs in order to gather and analyze performance and handling qualities data in order to determine if an aircraft meets its design and performance goals and certification requirements.

Mengembangkan Mesin Pesawat Terbang

"Ketika ayah saya meninggal sedang shalat, Ibu Saya bersumpah bahwa anak-anaknya kelak akan berguna bagi masyarakat, bangsa dan agama" 
~Prof. Habibie~


Sebuah Cita-cita mengembangkan Permesinan untuk Pesawat Terbang


An aircraft engine is the component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines.




Aircraft Engine Manufacturing Industry 

In 2012, the size of the aircraft engine manufacturing market was almost $40 billion. There are over 350 manufacturing companies in the United States employing over 70 thousand. For a list of all manufacturers in the world see the List of aircraft engines.

Turbojet Engine


Turbojets consist of an air inlet, an air compressor, a combustion chamber, a gas turbine (that drives the air compressor) and a nozzle. The air is compressed into the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine into the nozzle where it is accelerated to high speed to provide propulsion.

Ilmu dan Teknologi Misil

“Saya bangga bisa menyapu jalanan di Teheran.” 
~Dr. Mahmud Ahmadinejad~

Iran's Missiles


In a modern military, a missile is a self-propelled guided weapon system, as opposed to a unguided self-propelled munition, referred to as just a rocket (weapon) . Missiles have four system components: 

targeting and/or guidance, flight system, engine, and warhead. 

Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballisticcruiseanti-shipanti-tank, etc.), surface-to-air missiles (anti-aircraft and anti-ballistic), air-to-air missiles, and anti-satellite missiles. All known existing missiles are designed to be propelled during powered flight by chemical reactions inside a rocket enginejet engine, or other type of engine. 

Non-self-propelled airborne explosive devices are generally referred to as shells and usually have a shorter range than missiles.

Lockheed Martin’s Theater High Altitude Area Defense (THAAD) System



The word missile comes from the Latin verb mittere, meaning "to send".
In military usage, munitions projected towards a target are broadly categorised as follows:
  • A powered, guided munition that travels through the air or space is known as a missile (or guided missile.)
  • A powered, unguided munition is known as a rocket.
  • Unpowered munitions not fired from a gun are called bombs whether guided or not; unpowered, guided munitions are known as guided bombs or "smart bombs".
  • Munitions that are fired from a gun are known as projectiles whether guided or not. If explosive they are known more specifically as shells or mortar bombs.
  • Powered munitions that travel through water are called torpedoes (an older usage includes fixed torpedoes, which might today be called mines).
  • Hand grenades are not usually classed as missiles.
A common further sub-division is to consider ballistic missile to mean a munition that follows a ballistic trajectory and cruise missile to describe a munition that generates lift.

Teknologi Pesawat Tempur Siluman


Advanced avionics give the pilot real-time access to battle space information with spherical coverage and an unparalleled ability to dominate the tactical environment. Data collected by F-35 sensors can be immediately shared with commanders at sea, in the air or on the ground, providing an instantaneous, high-fidelity view of ongoing operations – making the Lightning II a formidable force multiplier.  

The F-35’s built-in sustainment establishes new levels of operational readiness. Aircraft share common parts, support equipment and technical data, yielding greater reliability and long-term cost savings. And the F-35’s strong global partnership and broad industrial base ensures affordability through economies of scale while delivering thousands of technology sector jobs around the world

Berbagai Macam Jurnal Aerospace


"Kebahagiaan dan kesedihan tergantung bagaimana kita menyikapinya"
~Prof. B.J. Habibie~


Aerospace comprises the atmosphere of Earth and surrounding space. Typically, aerospace industries combine aeronautics and astronautics to research, design, manufacture, operate, or maintain vehicles moving through air and space. Aerospace is a very diverse field, with a multitude of commercial, industrial and military applications.
Along with these public space programs, many companies produce technical tools and components such as spaceships and satellites. Some known companies involved in space programs include BoeingEADSLockheed MartinMacDonald Dettwiler and Northrop Grumman. These companies are also involved in other areas of aerospace such as the construction of aircraft.
