Sigurd A. Sjoberg

Sigurd A. Sjoberg is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sigurd A. Sjoberg rather than just read about it. In short: Sigurd Arnold Sjoberg (September 2, 1919 — March 26, 2000) was the deputy director for the Manned Spacecraft Center from 1972 to 1979. Before his deputy director tenure, Sjoberg started his space career in 1942 with the National Advisory Committee for Aeronautics.

Key takeaways

  • Sigurd A. Sjoberg belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sigurd A. Sjoberg to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sigurd A. Sjoberg from memory before moving on to harder problems.

Reference excerpt

Sigurd Arnold Sjoberg (September 2, 1919 — March 26, 2000) was the deputy director for the Manned Spacecraft Center from 1972 to 1979. Before his deputy director tenure, Sjoberg started his space career in 1942 with the National Advisory Committee for Aeronautics. As a member of the Langley Memorial Aeronautical Laboratory until the end of the 1950s, Sjoberg worked in aerodynamics and primarily conducted research. For his flight operations career, Sjoberg joined the Langley Research Center and Space Task Group in 1959. After four years at Langley, Sjoberg was the deputy director for the MSC's flight operations department throughout the remainder of the 1960s. He also was the flight operations department's director from 1969 to 1972. While at NASA, Sjoberg worked on Project Mercury, Project Gemini and Project Apollo before leaving NASA in 1979. During the 1970s, some awards that Sjoberg received include the Presidential Medal of Freedom, NASA Distinguished Service Medal and Space Flight Award. He also became a member of the National Academy of Engineering and Fellow of the American Institute of Aeronautics and Astronautics.

Early life and education On September 2, 1919, Sjoberg was born in Minneapolis, Minnesota. Growing up, he lived with his two siblings and Swedish parents. For his post secondary education, Sjoberg graduated with a Bachelor of Science degree from the University of Minnesota in 1942 and specialized in aeronautical engineering.

Career

NACA After completing his studies, Sjoberg started his career with the National Advisory Committee for Aeronautics in 1942 when he worked in aerodynamics. As part of their Langley Memorial Aeronautical Laboratory, Sjoberg focused on aircraft stabilizers during World War II in the Flight Research Division. In 1946, Sjoberg started a decade long position at Langley as a Research Scientist. Throughout the remainder of the 1950s, Sjoberg worked in Langley as their Airborne Analysis lead. Outside of Langley, Sjoberg briefly worked for the Douglas Aircraft Company during the mid 1940s in aerodynamics. As part of the NACA High Speed Flight Station, Sjoberg focused on several x-planes by Bell Aircraft and the Douglas D-558 until the end of the 1940s.

NASA For his NASA career, Sjoberg joined the Space Task Group in 1959. With the task group, Sjoberg worked on Project Mercury until the early 1960s. During this time period, Sjoberg began his thirteen-year flight operations experience when he joined the Langley Research Center in 1959. After completing his four-year coordinator tenure at Langley, Sjoberg started out as an assistant for the Manned Spacecraft Center in 1962. While at the flight operations department for the MSC, Sjoberg was their deputy director from 1963 to 1969 before becoming their flight operations director at the end of 1969. During his tenure, Sjoberg was part of the operations team when the Apollo 13 accident occurred in 1970. By 1972, Sjoberg had worked on Project Gemini and multiple spaceflights of Project Apollo. That year, Sjoberg became the deputy director for the MSC and took over Christopher C. Kraft Jr.'s position. In 1973, the Manned Spacecraft Center was renamed to the Lyndon B. Johnson Space Center. While Skylab and the Apollo Soyuz Test Project were undergoing throughout the 1970s, Sjoberg continued to be part of Project Apollo. Sjoberg remained as deputy director until he ended his NASA career in 1979. That year, Sjoberg became the director of OAO Corporation for their Houston branch.

Awards and honors

From NASA, Sjoberg received the NASA Exceptional Service Medal in 1969. He was also presented with the NASA Distinguished Service Medal in 1971. In April 1970, Sjoberg and the MSC were awarded the Presidential Medal of Freedom. From the University of Minnesota, Sjoberg received the Outstanding Achievement Award in 1973. From the American Astronautical Society, Sjoberg received the Space Flight Award in 1976 and the William Randolph Lovelace II Award in 1977. He also became a fellow for the American Astronautical Society. Outside of the AAS, Sjoberg was named to the National Academy of Engineering in 1974. He was selected to be a Fellow of the American Institute of Aeronautics and Astronautics in 1976.

Personal life and death Sjoberg was married and had three children. His death occurred at Clear Lake, Texas during March 26, 2000.

Worked examples

Example 1 — a first encounter with Sigurd A. Sjoberg

Start with the simplest possible case. Write down what Sigurd A. Sjoberg claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sigurd A. Sjoberg before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sigurd A. Sjoberg ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sigurd A. Sjoberg

In research
Sigurd A. Sjoberg appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sigurd A. Sjoberg in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sigurd A. Sjoberg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1919 births, 2000 deaths, Apollo 13, so understanding it makes those chapters shorter.
In everyday life
Look for Sigurd A. Sjoberg outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
