Abstract Innovations and modifications that produce cost reductions and enhance performance have driven the evolution of the classic solid rocket and the liquid bipropellant rocket into hybrid models that integrate the predominant solid and liquid model features into more sensical, more economical fabrications of design. The commercial spacecraft demands for aerospace propulsion have also evolved to include a market for environmentally sustainable hybrid rocket engines that has yet to fully mature to the Technology Readiness Level (TRL). Numerical modeling has been used as a tool to test the feasibility of new solid fuel types. ABS has been considered as ...

The investigation on The Burj Dubai tower and the Taipei 101 building

The Burj Dubai tower The Burj Dubai tower is one of the world tallest buildings to have ever been constructed by engineers. This type of a building wind forces and the resulting motions in the upper chamber of the building become some of the factors that call for a major concern in the construction of the building. Engineers had to make an extensive research programs in wind tunnels in the Rowan, Williams, Davies and Erwin (RWDI) 2.4 ×1.9 meter, and 4.9 × 2.4 meter boundary layer wind tunnels in Guelph, Ontario. In the wind tunnel program, it includes pedestrian wind environment ...

Every commercial aircraft is fundamentally designed for safety, passenger acceptance, fuel efficiency and airport compatibility among other important features. Numerous challenges face all current passenger aircrafts, for instance the conventional wing consists of a number of moving parts which increase the weight of the plane and are difficult to adjust and maintain. The current control surfaces also increase turbulence and drag since the smooth flow of air is disrupted, and the aircraft cannot adapt to different flight stages and conditions. Design architectures such as the vertical and horizontal stabilizer surfaces increase the overall drag of the plane, for example, the ...
