In fact, basic aerodynamic tests are sometimes performed underwater. To put it simply, a salmon essentially flies through the sea, and a pelican swims through the air. The core of the matter is this: Even a clear sky isn't empty. Our atmosphere is a massive fluid layer, and the right...
To calculate the drag force, it is assumed that the drag coefficient (CD) is typically around 2.2 and that the cross-sectional area (A) of Starlink satellites is approximately 15.45 m2 (Hardy 2020). We attempted to examine the decay of altitude on Starlink satellites using the Two Line ...
To calculate the amount of power a turbine can actually generate from the wind, you need to know the wind speed at the turbine site and the turbine power rating. Most large turbines produce their maximum power at wind speeds around 15 meters per second (33 mph). Considering steady wind spe...
If your periapsis is too high you will need to burn retrograde after the aerobrake to achieve an orbit. Duna's highest terrain is around 8500m high, so placing your periapsis below that is not recommended even for the bravest. A heat shield might be necessary, but a good aerodynamic ...
NASA is making history with a 4-pound helicopter named Ingenuity. The world is about to witness an attempt of the first powered flight on another planet.
To calculate the gear ratio or development you must count the teeth of the pinion and the crown and perform the following calculation: Crown Teeth / Pinion Teeth The chain is the connecting element between the pinion, located on the motor, and the crown, on the rear axle. The chain must ...
Calculate the total cost of the parts for your race car. Consider factors such as the quantity of each part required for the car. This will help you establish a budget for your team and ensure that your expenses align with your available resources. ...
Moreover, the collected data is also used to calculate the size of the harvest, which in practice means that the producer can avoid overproduction. Blue River Technology has developed a technology that utilises cameras and information processing by artificial intelligence algorithms to accurately monito...
ofboundary layer separation(a source of drag and in the worst-case scenario aerodynamic stall). A similar streamline profile could also be created with a symmetric airfoil that introduces asymmetry into the flow by being positioned at a positive angle of attack....
To reduce the need for software development and shorten time-to-market, the DS2788 utilizes an embedded fuel gauge algorithm to calculate remaining capacity based on precision coulomb count, discharge rate, temperature and cell characteris- ditions, even as a battery ages. In addition to the ...
