Simulation Software Improves Pilot Training

Simulation of a helicopter landing on a ship. (Chair of Helicopter Technology/TUM) Providing pilots with the best possible preparation for extreme situations is the goal of new simulation software. The program that combines flow mechanics and flight dynamics in real time. The numerical model is extremely flexible and does not depend on stored flow data. External conditions such as topography, global wind speeds, and aircraft type are input. During the simulation, the algorithms use that data to continuously compute the interacting flow field at the virtual aircraft’s current location.

Computer Model More Accurately Predicts Flight Delays

Sina Khanmohammadi, a PhD candidate in systems science, leads a Binghamton University study that has developed a more accurate way of predicting airline flight delays. (Jonathan Cohen) Researchers at Binghamton University have devised a new computer model that can more accurately predict delays faster than anything currently in use. The multilevel input layer artificial neural network handles categorical variables with a simple structure to help airlines easily see the relationships between input variables (such as weather) and outputs (flight delays).

Aircraft Arrival Technology Will Reduce Flight Delays

Retired airline pilots test procedures that will be used during upcoming flight tests of FIM. The simulator is set up like a Boeing 757 jet. (NASA Langley/David C. Bowman) Flight Deck Interval Management (FIM) promises to safely increase the number of airplanes that can land on the same runway at busy airports by more precisely managing the time, or interval, between each aircraft arrival.

Pushbroom Stereo for High-Speed UAV Navigation in Cluttered Environments

The high-frame-rate stereo detection system requires no external sensing.Unmanned aerial vehicles (UAVs) rely on an external motion-capture apparatus that gives the vehicles almost perfect state information at high rates. Major challenges in gathering sensing data necessary for flight are the limited payload, computation, and battery life of the vehicles. Lightweight cameras are a good solution, but require computationally efficient machine vision algorithms that can run within the limits of these vehicles.

Modeling and Simulation of an Unmanned Ground Vehicle Power System

These models can be used to plan missions or roughly estimate power system operation for an unmanned ground vehicle.Robotic vehicles such as unmanned ground vehicles (UGVs) have multiple sources of power, including batteries, fuel cells, combustion engines, ultracapacitors, and solar cells to allow for extended periods of operation. Fuel-based power sources have a higher specific energy than batteries, which is why most current automobiles are gasoline-powered. Batteries have many other advantages in terms of low noise profile, easy replacement, and direct energy conversion. Solar charging allows for harvesting of natural resources to increase total energy reserves. Mission duration may be maximized using a combination of power systems.
