Relationship between location of center of gravity and stability of an airfoil/control surface.
The longitudinal spacing of aircraft at the same altitude with the minimum distance expressed in units of time. Longitudinal separation is achieved by requiring aircraft to depart at a specified time, to lose time to arrive over a geographic location at a specified time, or to hold over a geographical location until a specified time. Longitudinal separation between supersonic aircraft during the transonic acceleration and supersonic phase of flight is achieved by timing the start of the transonic acceleration appropriately rather than by imposing speed restrictions during supersonic flight.

While fittings are available in push-on or mechanical joints, they do not offer restraint against longitudinal separation. When these fittings are used, the pressure inside the pipeline creates a thrust force that would move the fitting and cause joint separation if not addressed.
The paper presents the analysis of the influence of the separations between vessels on the motions of the vessels, examining the influence of latitudinal and longitudinal separation between the vessels and recorded some really good validation data for computer models.
the subject of this invitation to tender is the delivery, installation and commissioning of a 110 kv sf6 switchgear with 5 cubicles as a single busbar with longitudinal separation including connection to protective and control cabinets, as well as all disassembly and disposal of the old system.
The new switchgear consists of: - 10 line fields, - 1 reserve line field, - 2 feed-in fields (mains coupler 200 mva), - 2 transformer fields, - 1 reserve transformer field, - 2 charge current compensation coil fields, - 1 triple busbar with 1 longitudinal separation and 2 busbar dome panels.
For a three-year period a total of about 65 pieces panels about 20 cubicles for transformer feeders and 30 switching fields for longitudinal separation fields is responsible for overall management branches, assumed.
