The History of Rocket Science
Rocket technology has evolved for more than 2000 years. Today’s rockets are a product of a long tradition of ingenuity and experimentation, and combine technical expertise from a wide array…
What is the construction of a marine diesel engine piston used on board ships?
Introduction We started to learn about one of the most important marine diesel engine components namely the piston in the previous article. In this article we will proceed to learn about the…
Rocket Science 101: Operating Principles
In a previous post we covered the history of rocketry over the last 2000 years. By means of the Tsiolkovsky rocket equation we also established that the thrust produced by a rocket is equal…
Rocket Science 101: Fuel, engine and nozzle
This is the third in a series of posts on rocket science. Part I covered the history of rocketry and Part II dealt with the operating principles of rockets. If you have not checked…
Governing of IC Engines
(1) In petrol engines control is accomplished by means of a throttle valve which is placed in the intake manifold immediately following the carburetor. The amount of opening of the…
Rocket Science 101: Lightweight rocket shells
This is the fourth and final part of a series of posts on rocket science. Part I covered the history of rocketry, Part II dealt with the operating principles of rockets and Part III looked at…
Methods of Starting IC Engines
Starting devices are commonly employed with compression ignition engines and especially with the engines fitted with turbulence combustion chambers. Petrol engines as well as gas engines and small units of…
Supersonic Aerodynamics: Designing Rocket Nozzles
One of the most basic equations in fluid dynamics is Bernoulli’s equation: the relationship between pressure and velocity in a moving fluid. It is so fundamental to aerodynamics that it…
Supercharging of IC Engines
Supercharging is the name given to the process of increasing the pressure of the air-fuel mixture entering a petrol engine to a pressure greater than that of atmospheric air and…
Composite Materials and Renewables: Wind Energy
In the aerospace industry the benefits of exploiting the excellent specific strength and stiffness properties of composites in terms of lightweight structural design are immediately apparent. Other advantages of fibre…
