We will give here only a short explanation of the operation of the plant and deal principally with the question of what it has accomplished
Perancangan Interior Japanese Action Figure Center Di Surabaya
Japanese Action Figure Center in Surabaya is intended for lovers of action figures to be able to buy , assemble , and respond to their needs to provide a place that has the style of anime in Surabaya . The concept of this design is stylish and modern techno , which impressed futuristic design , and followed by the use of advanced technology in order to access the facilities in place . Brand image of the product sold itself is "imaginative and communicative " where the figure lovers will immediately be able to imagine the feel of the place is so into it . Therefore the design of the room is really an implementation of anime , or the character of the game , combined with a modern interior style
Flap-lag dynamics of hingeless helicopter blades at moderate and high advance ratios
Equations for large amplitude coupled flaplag motion of a hingeless elastic helicopter blade in forward flight are derived. Only a torsionally rigid blade exicted by quasi-steady aerodynamic loads is considered. The effects of reversed flow together with some new terms due to forward flight are included. Using Galerkin's method the spatial dependence is eliminated and the equations are linearized about a suitable equilibrium position. The resulting system of equations is solved using multivariable Floquet-Liapunov theory, and the transition matrix at the end of the period is evaluated by two separate methods. Results illustrating the effects of forward flight and various important blade parameters on the stability boundaries are presented
Calculated Hovering Helicopter Flight Dynamics with a Circulation Controlled Rotor
The influence of the rotor blowing coefficient on the calculated roots of the longitudinal and lateral motion was examined for a range of values of the rotor lift and the blade flap frequency. The control characteristics of a helicopter with a circulation controlled rotor are discussed. The principal effect of the blowing is a reduction in the rotor speed stability derivative. Above a critical level of blowing coefficient, which depends on the flap frequency and rotor lift, negative speed stability is produced and the dynamic characteristics of the helicopter are radically altered
