Guidance, navigation, and control systems consist of 3 essential parts: navigation which tracks current location, guidance which leverages navigation data and target information to direct flight control "where to go", and control which accepts guidance commands to affect change in aerodynamic and/or engine controls.
Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch , roll and yaw .
A spacecraft's attitude must typically be stabilized and controlled for a variety of reasons. It is often needed so that the spacecraft high-gain antenna may be accurately pointed to Earth for communications, so that onboard experiments may accomplish precise pointing for accurate collection and subsequent interpretation of data, so that the heating and cooling effects of sunlight and shadow ...
Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. [1] It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics.
During arguments at the U.S. Supreme Court in this week's major transgender rights case, liberal Justice Sonia Sotomayor told the lawyer defending Tennessee's ban on gender-affirming medical care ...
By Jody Godoy (Reuters) -A U.S. judge blocked the pending $25-billion merger of U.S. grocery chains Kroger and Albertsons on Tuesday, in a win for the Federal Trade Commission that Kroger has said ...
The Sunset Fire broke out the evening of Jan. 8 in the Runyon Canyon area of the Hollywood Hills, forcing a new set of evacuations. It had burned dozens of acres of vegetation, officials said.
A new track that begins in or near the capture volume of an active track is called a split track. Coasted track, joined track, and split track trigger an operator alert. For example, a track coast can result from an aircraft collision, so the cause needs to be determined otherwise supervisory personnel need to be notified.
