DLR Case Study

Superior Essays
DLR’s mission comprises the exploration of the Earth and the solar system, as well as research aimed at protecting the environment and developing environmentally compatible technologies, and at promoting mobility, communication and security. DLR’s research portfolio, which covers the four focus areas Aeronautics, Space, Transportation and Energy, ranges from basic research to innovative applications. DLR operates large-scale research centres, both for the benefit of its own projects and as a service for its clients and partners from the worlds of business and science.
The objective of DLR’s aeronautics research is to strengthen the competitive advantage of the national and European aeronautical industry and aviation sector, and to meet political

The objective of this five-year mission is to provide radar remote sensing data to scientific and commercial users. The satellite’s design is based on the technology and expertise developed in the X-SAR and SRTM SAR missions (Synthetic Aperture Radar). The sensor has a number of different modes of operation, with a maximum resolution of one meter, and is capable of generating elevation profiles.
TerraSAR-X is the first satellite that was jointly paid for by government and industry. DLR contributed about 80 percent of the total expenses, with the remainder being covered by EADS Astrium. The satellite's core component is a radar sensor operating in the X band and capable of recording the Earth’s surface using a range of different modes of operation, capturing an area of 10 to 100 kilometers in size with a resolution of 1 to 16 meters.
Suborbital Spaceplane[edit]
Studying a suborbital spaceplane, DLR conducted Falke prototype for Hermes spaceplane program, participates in non-realized Sanger II project and since 2005 work under the concept making fast intercontinental passenger transport possible. The so-called SpaceLiner is a reusable vehicle lifting-off vertically and landing like a glider.

In order to ensure that increasing traffic volumes do not lead to an increase in the noise pollution caused by air transport, DLR is investigating options for noise reduction. The "Low-noise Approach and Departure Procedures" research project (German: Lärmoptimierte An- und Abflugverfahren), for instance, forms part of the national research project "Quiet Traffic" (German: Leiser Verkehr). The objective of this project is to find flight procedures that can reduce the amount of noise generated during takeoff and landing. One approach is to analyse noise propagation at ground level during takeoff using a large number of microphones. Researchers are also trying to reduce the noise at source, focusing for instance on airframe and engine noise. They hope to minimise noise generated in the engines using so-called

    The modern times has seen even more NASA budget cuts and a rise in private contractors looking to space. The budget cuts may even be costing the US more than its saving them. A writer from the washington post says “Since the shuttle 's retirement, the United States has been forced to rely on Russia to take its astronauts to the station, an expensive and troubling arrangement that now costs $76 million per seat” (Davenport). There are multiple astronauts on the space station with multiple launches a year, the price of using rockets could severely add up. Most recently in the bid for cheaper space travel are the contracting of private corporations.…

    Many people are concerned about the dangers that cell phones pose, and they are told that keeping it a greater distance from their heads and using devices such as headphones can diminish much of the radiation; all of which is true. Unfortunately, since the technology industry has made the invention of wireless headphones, if people use their cell phones in conjunction with these devices, the radiation dosage can be even greater than normal. Using Bluetooth, the main type of wireless communication between devices, can have just as much electromagnetic radiation as talking on the phone. One team realized this and began to test the power density rating and the specific absorption rate (SAR), both of which measure radiation dosages. This team…

    Similar to the explorations of the New World and South America to be conquered, space is the modern conquest where we endeavor to survey our solar system and investigate the vast universe. What first arose as an idea in the 1950s, it has continued to expand advancing the rate of technological improvement. Some would say, other than exploration what greater influence has the reconnaissance of space brought upon? Other than analyzing different spectrums of the galaxy, the conquest of space led to an exchange of ideas between different nations in efforts to improve their spaceships and space technologies. The Soviet Union was the first country to send an orbiting satellite around Earth, for this started the fundamentals of space exploration and…
