The nature of the fuel best suited to each type of propulsive engine is determined principally by the characteristics of combustion in that engine, but all aviation fuels must also meet the requirements of the aircraft fuel system, the distribution system, and the financial climate generally. The...
Open Sustainable TechnologyA directory and analysis of the open source ecosystem in the areas of climate change, sustainable energy, biodiversity and natural resources. Earth's uniqueness in creating a stable environment for life in a completely hostile space is a miracle. Various life forms have ta...
The calculators we know today were first invented in the 1960s, and the use of smartphones as calculators began in the 1990s. However, that does not mean that mathematical tools weren’t available a century ago. Several computing machines were made long before the arrival of digital calculators...
This type of arc welding process can have a high metal deposition rate of up to 20 kg/hour. It also has a capacity for welding metals with thicknesses up to 100mm. This type of welding is often used in heavy fabrication industries. The aviation industry, shipbuilding, railroads, and bridg...
Exergo-sustainability indicators of a turboprop aircraft for the phases of a flight Abstract One of the key challenges for sustainable aviation is to reduce global and local environmental impacts. The scope of this study is analysed and di... HATHK Midilli - 《Energy》 被引量: 25发表: 2013年...
The Jet-Flame forced draft retrofit accessory was recently developed to implement forced jets of primary air at a low cost into a wide range of types of cookstoves using a small 1.5-W fan housed in a low-cost cast iron body to be inserted beneath the fuel bed of a biomass cooking fire...
To solve these problems, an enormous development of clean, sustainable, and high-performance applications for energy conversion (such as solar cells, wind and wave energy convertors, thermoelectric generators, etc.) as well as for energy storage (such as batteries, supercapacitors, capacitors, etc....
Some of those options include more sustainable ones like Perlon straps made from recycled materials and leather straps made from sustainably sourced and tanned deer leather through Oris’s partner Cervo Volante. With screwed crown and solid caseback, the Unomat is water-resistant up to 30 bar ...
One place that AM is making a significant inroad is in the aviation industry. With nearly 3.8 billion air travelers in 2016,[36]the demand for fuel efficient and easily produced jet engines has never been higher. For large OEMs (original equipment manufacturers) like Pratt and Whitney ...
