An aircraft designer today would likely view the idea of using a steam engine to power an airplane as impractical and outdated. Modern aviation relies on engines that provide high power-to-weight ratios and efficiency, features that steam engines struggle to achieve due to their bulk and weight. Additionally, advancements in materials and aerodynamics have led to designs optimized for jet or turboprop engines, making steam technology less viable for contemporary aircraft. Overall, while steam engines played a significant role in early aviation, they are not aligned with today's performance and efficiency standards.
The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.
Horizontal search engines are general-purpose search engines such as Google and Yahoo. Vertical search engines, meanwhile, are specialized by content such as Trulia, Mocavo and Yelp.
yes car engines are pulleys
A Boeing 747 has four engines.
It is not commercially viable.
Not commercially viable.
Although experimental organic fibers existed as early as 1913, the first commercially viable synthetics were invented during the 1930s and 1940s.
It depends if the producers consider it commercially viable.
"Commercially viable" refers to a product or service that is able to generate enough revenue to cover its costs and create a profit. It indicates that there is a market demand for the offering and that it can be sustained or scaled effectively in the marketplace.
Only if someone can make money from it. It will have to be commercially viable.
No. Boeing and Airbus do not have any supersonic planes which are commercially viable for airtravel yet
Make changes in the operation so as to be able to increase production to a commercially viable level.
There are no commercially available or viable electric cars on the market today. The answer is virtually zero.
Because the managers think that is the most commercially viable option.
Corn needs large plots of land to be economically viable as a crop, so it is not grown commercially in any cities.
There used to be a British make of car called Wolseley. The world's first commercially viable rotary engine was the Wankel engine.
