Which came first sonar or radar?
During the 1930s American engineers developed their own underwater sound-detection technology, and important discoveries were made, such as the existence of thermoclines and their effects on sound waves. Americans began to use the term SONAR for their systems, coined by Frederick Hunt to be the equivalent of RADAR.
Did Japanese have radar in ww2?
Both the Japanese and the Allies developed radar countermeasures during the war, but Japanese radar countermeasures trailed behind those of the Allies. The Allies first recognized that the Japanese had significant radar capability with the capture of the “Guadalcanal radar” in August 1942.
Did Germany invent radar?
Germany. A radio-based device for remotely indicating the presence of ships was built in Germany by Christian Hülsmeyer in 1904. Often referred to as the first radar system, this did not directly measure the range (distance) to the target, and thus did not meet the criteria to be given this name.
Did the Luftwaffe have radar?
German Luftwaffe and Navy Kriegsmarine Radar Equipment during World War II, relied on an increasingly diverse array of communications, IFF and RDF equipment for its function. During the war, Germany renumbered their radars.
How did they detect aircraft before radar?
The 20th century ‘war tubas’ used to spot warplanes before radar. Before the invention of radar during World War II, incoming enemy warplanes were detected by listening with the aid of “sound locators” that looked more like musical instruments than tools of war.
Does radar travel at the speed of light?
The radio waves travel outward from the antenna at the speed of light (186,000 miles or 300,000 km per second) and keep going until they hit something. The antenna doubles up as a radar receiver as well as a transmitter. In fact, it alternates between the two jobs.
What is the big concrete thing in back to life?
The Dungeness mirrors, known colloquially as the “listening ears”, consist of three large concrete reflectors built in the 1920s–1930s.
Will we ever run out of concrete?
highly unlikely. Concrete and steel, as they are, are here to stay. You can add certain things and modify the mix, but the basics will remain the same. Say we do run out, there’s something called Seament which is created by having an electrical current run through minerals within salt water.
How long will concrete last?
For large scale projects like buildings, concrete should last up to 100 years if it’s properly cared for. Concrete projects that experience more wear-and-tear like sidewalks and driveways have an expected lifespan of about half that—50 years.
Who invented concrete?
600 BC – Rome: Although the Ancient Romans weren’t the first to create concrete, they were first to utilize this material widespread. By 200 BC, the Romans successfully implemented the use of concrete in the majority of their construction. They used a mixture of volcanic ash, lime, and seawater to form the mix.
What is the strongest concrete mix ratio?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
Why is Roman concrete so strong?
The concrete is made of quicklime, or calcium oxide, and volcanic ash. Minerals called Al-tobermorite and phillipsite form as the material leaches mineral-rich fluid that then solidifies, reinforcing the concrete and making the structures even stronger.
What is the strongest concrete in the world?
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to achieve specified requirements …
Is Roman concrete really better?
As it turns out, not only is Roman concrete more durable than what we can make today, but it actually gets stronger over time. This aggregate has to be inert, because any unwanted chemical reaction can cause cracks in the concrete, leading to erosion and crumbling of the structures.
