ERAST programme develops pilotless solar powered airplane technology. The HELIOS construction is based upon its predecessors like NASA’s solar plane Pathfinder‚ which was successfully tested a few years prior to HELIOS. Due to its speed HELIOS was able to fly over the same spot for days or weeks‚ therefore‚ in the future such aircrafts could substitute communication

The German government played an important role in the rejuvenation of the economy so the German state and the economic system are closely intertwined.

Aircraft Pressurization System Airplanes‚ which do not have pressurization and air conditioning systems‚ are usually limited to the lower altitudes. They need to stay below 8‚000 feet. A cabin pressurization system accomplishes several functions in providing passengers comfort and safety. It maintains a cabin pressure altitude of approximately 8‚000 feet at the maximum designed cruising altitude of the airplane‚ and prevents rapid changes of cabin altitude‚ which may be dangerous to the passengers

various film style and film form techniques. One of the main styles which defined German Expressionist films was the manipulation of mis-en-scene; this included creating twisted and distorted sets‚ actors using strange and dance-like movements and costumes and appearances tending to be over-exaggerated and outrageous (Horak‚ 2010‚ Moran‚ 2010‚ Read‚ 2010‚ Thompson and Bordwell‚ 2008). During this time‚ the culture of German Expressionism boomed as cinema-goers were excited and interested in the strange

Designing a Safer Passenger Aircraft Introduction to air safety: Aircrafts have become more advanced and fast‚ but they are drastically affected by ignorance and design incapability. However these structures can fly with more than 200 passengers and heavy cargo‚ but when they crash‚ they take away with them many lives and damage valuable property. To prevent such loses several aviation safety agencies like EASA(European Aviation Safety Agency) and FAA(Federal Aviation Administration) have been

Aircraft structures Abstract: The aircraft structure is an important part where the structure of an aircraft depends on the optimum requirement of the customer and the environments in which it will be going to fly for the major time. It has to go several checks at regular interval of flying hours under proper inspection. This paper contains the basic information regarding the components of an aircraft and the basic concept of its design. The main criteria of design and its philosophy is the

New study area This week I have learned more about the interior part of the aircraft which is the cabin layout in most aircraft . Seats are frequently equipped with further amenities. Airline seats may be equipped with a reclining mechanism for increased passenger comfort‚ either reclining mechanically or electrically (usually in long-haul first class and business class). Most aircraft also feature trays for eating and reading‚ either in the seatback which folds down to form a small table

What Are Aircraft? Everyone has seen a jet streaking across the sky leaving a trail of vapor as it goes. Maybe you have heard the distinct thud‚ thud‚ thud as a helicopter slows in its descent. You have probably marveled at a plane so massive that it seems to just hang in the air by some invisible force. These wonderful marvels of human engineering have captured the hearts of many. They are known the world over as aircraft. But what is an aircraft? Aircraft’s are comprised of many different things
