Design Example: Calculating Safe Diameter for Wind-Exposed Disc

Design Example: Calculating Safe Diameter for Wind-Exposed Disc

Assessing safety in wind-exposed installations is crucial to preventing potential failures. This example explores the calculation and design adjustments needed to mount a circular disc on a building facade, where wind forces are a primary concern. A 4-meter diameter disc was initially designed as an aesthetic feature facing winds at a velocity of 25 meters per second, with an air density of 1.25 kilograms per cubic meter. Given these conditions, the drag force on the disc was determined using...

Vectors in 2D: Problem Solving

Vectors in 2D: Problem Solving

A plane traveling due north at 180 km/h in still air was found to be 80 km off-course after 30 minutes, deviating approximately 5 degrees east of north. This deviation means the influence of a crosswind alters the plane’s intended trajectory. The actual ground path formed a diagonal, suggesting that the aircraft’s effective ground speed was reduced to 160 km/h and directed slightly to the east due to the wind.By analyzing the displacement from the intended path, the velocity contributed by the...

Boundary Layer Characteristics

Boundary Layer Characteristics

When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...

Pole and System Stability

Pole and System Stability

The transfer function is a fundamental concept representing the ratio of two polynomials. The numerator and denominator encapsulate the system's dynamics. The zeros and poles of this transfer function are critical in determining the system's behavior and stability.
Simple poles are unique roots of the denominator polynomial. Each simple pole corresponds to a distinct solution to the system's characteristic equation, typically resulting in exponential decay terms in the system's response.

Azimuths and Bearings

Azimuths and Bearings

Azimuths and bearings are essential concepts in surveying, providing methods to express the direction of a line relative to a meridian. Azimuths refer to the clockwise angle measured from the north end of a reference meridian to the given line, ranging from zero to 360 degrees. This method gives a comprehensive directional reference within a full 360-degree circle, making it a straightforward way to communicate direction in various fields, including navigation, cartography, and...

Circular Orbits and Critical Velocity for Satellites

Circular Orbits and Critical Velocity for Satellites

The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.
Nicolaus Copernicus (1473-1543) first suggested that the Earth and all other planets orbit the Sun in...

Area of Science:

Atmospheric Science
Earth Observation
Satellite Remote Sensing

Background:

The PARASOL satellite joined the A-train observatory in 2004, complementing other advanced atmospheric instruments.
It utilizes a wide field-of-view radiometer derived from the POLDER program for visible/near-infrared measurements.

Purpose of the Study:

To present an overview of PARASOL's commissioning phase and post-launch performance evaluations.
To assess the radiometric and geometric performance of the PARASOL payload.
To detail in-flight calibration methods and algorithm adaptations for the PARASOL mission.

Main Methods:

Evaluation of radiometric and geometric performances using natural targets.
Adaptation and redevelopment of algorithms from previous POLDER missions.
Application of an innovative multitemporal algorithm for radiometric sensitivity correction.

Main Results:

PARASOL met most mission requirements, with band 443 not recommended for use.
Perfect geometric stability was observed after one year in orbit.
A slight decrease in radiometric sensitivity was identified and successfully corrected.

Conclusions:

PARASOL's performance meets mission objectives, enabling scientific exploitation.
The satellite's data can be coupled with other A-train sensor measurements for comprehensive atmospheric studies.
Ongoing monitoring and calibration ensure the reliability of PARASOL's atmospheric observations.
