static stability การใช้

• An aircraft with negative static stability can therefore be made more maneuverable.
• Another role of a longitudinal stabilizer is to provide longitudinal static stability.
• Digital fly-by-wire systems allow an aircraft to be designed with relaxed static stability.
• :: M _ \ alpha Pitching moment due to incidence-the static stability term.
• The relaxed static stability ( RSS ) was an ambitious requirement.
• Potential temperature is a useful measure of the static stability of the unsaturated atmosphere.
• Potential density is a dynamically important property : for static stability potential density must decrease upward.
• Static stability requires this to be negative.
• A free-floating mechanism may increase static stability and provide safe recovery from high angle of attack evolutions.
• At supersonic airspeed, a negatively stable aircraft can exhibit positive static stability due to aerodynamic center migration.
• Static stability also needs to be taken into consideration as it is necessary to maintain a high-drag altitude.
• The aerodynamic center plays an important role in analysis of the longitudinal static stability of all flying machines.
• However, positive static stability, the tendency to remain in its current attitude, opposes the pilot s efforts to maneuver.
• In the mesoscale, equivalent potential temperature is also a useful measure of the static stability of the unsaturated atmosphere.
• Fuselage geometry, engine nacelles and rotating propellers all influence lateral static stability and affect the required size of the stabilizer.
• This technique, called " relaxed static stability " ( RSS ), was incorporated to further enhance the aircraft s performance.
• Typically, computer based autopilots are required to control the vehicle when it has negative static stability-usually described as negative static margin.
• China set about to drop tanks in order to maintain a more stable center of gravity, and therefore better Longitudinal static stability.
• It is common practice to design manoeuvrable missiles with near zero static margin ( i . e . neutral static stability ).
• Being placed ahead of the center of gravity, a canard foreplane acts directly to reduce longitudinal static stability ( stability in pitch ).
