# Topic: Flight dynamics

###### In the News (Tue 19 Feb 19)

 Flight dynamics - Wikipedia, the free encyclopedia Flight dynamics is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are rotations in three dimensions around the vehicle's coordinate system origin, the center of mass. The motions relevant to dynamic stability are usually too short in duration for the motion of the Earth itself to be considered relevant for aircraft. en.wikipedia.org /wiki/Flight_dynamics   (3517 words)

 Reference Desk, Literature, Flight Mechanics, Performances, Aerodynamics One of the least understood problems of flight in the early days was the handling quality. The author starts from the basis of steady motion, free flight, symmetric and asymmetric moments, complete equations of motion, and includes numerical solutions for small disturbances (not a simple thing in the 1930s).

 Insect flight An important key to solving the mystery of insect flight, Wang said, is the understanding of the vortex "shedding" and how the vortices behave when they separate from the moving surface that created them. Any theory of insect flight has to account for both viscous and inertial effects, Wang said, noting that in a fluid environment like air, inertia is a force due to the motion of the fluid itself as fluid particles are carried along by their own velocity. Biologists with high-speed video cameras have been able to document the oscillating motions of insect wings as they move up and down and change pitch by tilting the edges, and the complex motions are beginning to be incorporated in the design of robotic "insect" wings. www.news.cornell.edu /Chronicle/00/3.30.00/insect_flight.html   (981 words)

Placing emphasis on dynamics and their importance to flying and handling qualities it is accessible to both the aeronautical engineer and the control engineer. www.amazon.fr /Flight-Dynamics-Principles-M-Cook/dp/0340632003   (431 words)

 FlightSim.Com Feature I saw this as great opportunity to look at the flight simulator world from the perspective of just one person who makes it so special. When I was asked to join PSS, the already nice.air file needed some changes to work flawless with the panel, as far flight simulator would let me. So, to answer your question; the 747 was for PSS already made.

 Head-up Guidance The presentation of all primary flight data in the pilot's forward field of view eliminates transitions from head-down to head-up flying. The pilot views this critical information, focused at optical infinity, as conformal with the outside world view. Using the displayed flight path and acceleration information, it is possible for the pilot to fly very accurate approaches to a precise landing in all conditions, even in turbulence, crosswinds and on fl hole approaches. www.rockwellcollins.com /page5680.html   (131 words)

 Aerospaceweb.org | Ask Us - Flight Dynamics Questions Flight dynamics is a rather broad area that relates the aerodynamic and propulsion characteristics of an aircraft to its flight characteristics, stability and control, and overall performance. While aerodynamics, propulsion, and performance are addressed in other sections, the questions answered here are primarily devoted to how planes are designed to make them stable and controllable during flight. The cruising speed for this plane is listed as 340 mph (547 km/h), but the trip from London Heathrow to New York is stated as taking 15 1/2 hours. www.aerospaceweb.org /question/dynamics   (433 words)

 Golf Ball's Interaction with Air It is the combination of the lift and drag properties of the ball, as well as its speed, launch angle and spin rate, which will dictate the flight path or trajectory of the ball, and thus the distance it will go. Most balls on the market today have thus converged to the middle ground with between 350 and 450 dimples (although one company produced a ball with 812, which didn’t set the world on fire). Although there are many factors which have a direct impact on increased driving distance over the past 2 decades, one of the most important factors for increased driving distance over the years is the golf ball. www.golfjoy.com /golf_physics/dynamics.asp   (648 words)

 Subject Listing for Flight dynamics In terms of flight mechanics the actuator displacement and force on the actuator are directly related to control surface deflection and hinge moment. Flight flutter tests are conducted to demonstrate freedom from flutter for critical aircraft conditi ons and to derive data to validate the flutter ana lysis. The flight test team felt that the three-ship formation data was inconclusive due to the difficulty of trying to fly a stable position as the third aircraft in the formation without station-keeping ability. aerade.cranfield.ac.uk /subject-listing/flight.html   (12784 words)

 Dynamics of Flight All these dimensions together combine to control the flight of the plane. Sometimes called speeds of flight, each regime is a different level of flight speed.

 AIN Online November 2003: Flight Dynamics expands head-up display capability   (Site not responding. Last check: 2007-11-03) Head-up display manufacturer Flight Dynamics, a division of Rockwell Collins, outlined its future technology strategy to AIN during a recent visit to the company’s Portland, Ore., facility. When AIN visited Flight Dynamics more than two years ago, a senior marketing manager stated that while EVS was an interesting concept, HGS already provided Cat III guidance and adding EVS might not repay what was then a very substantial investment. Finally, should the crew be uncertain about the aircraft’s actual position, they can instantly switch the HGS display to show a plan view of the airport’s runways and taxiways, with an aircraft symbol showing their location and, equally important, pointing in the direction they are headed. www.ainonline.com /issues/11_03/11_03_flightdynamicsp102.html   (786 words)
