At present, domestic cruise tourism is still an emerging tourism industry. Although all regions have great enthusiasm for the development of cruise tourism, some bottlenecks have appeared due to the lack of relevant planning. In terms of cruise manufacturing, such as large-scale fin stabilizers and low-speed design of engine, crankshaft, and propeller. To solve the above problems, it is very important to optimize the design of cruise travel routes based on wireless communication networks and genetic algorithms and research on economic development. This paper proposes the use of wireless sensor network (WSN) architecture and genetic algorithms in intelligent bionic algorithms to design cruise travel route optimization. Based on the research on the basic theory of the cruise industry, this article expounds the construction and operation of world-famous home ports and my country’s cruise home ports. Through the analysis and evaluation of the characteristics and development status of my country’s tourism and tourism resources, the possible impact of the construction of cruise home ports on the development of my country’s tourism industry under the new situation is discussed. The results of the study show that a cruise ship carrying 2010 tourists and 952 crew members will spend about 323,700 US dollars on shore tourists and crew every time it stops at its home port city. The average consumption is approximately US$273,000.

“…Similar to ramjet and scramjet aspirated engines, RBCC comprises of an inlet, a diffuser, a combustor and nozzles to process incoming air, add fuel, and expand the products combustion to generate thrust. The rocket is lighter and can provide thrust in a vacuum environment (1)(2)(3) . RBCC is typified by Marquardt's Mach 8 Supercharged Ejector Ramjet (SERJ) as shown in Fig.…”

The takeoff-mass of a two-stage-to-orbit Rocket-Based Combined Cycle Engine-Rocket (RBCC-RKT) launch vehicle is a crucial factor in its comprehensive performance. This paper optimizes the takeoff-mass together with the trajectory by reformulating it to a nonlinear optimal control problem. The range of the second stage rocket mass is considered as a process constraint. When the scopes of initial and terminal states are specified, the problem can be solved by using the Gauss pseudo-spectral method (GPM). In order to reduce the convergent difficulty caused by using table data, the data in different stages are utilized by employing an integrated interpolation strategy through the optimization. Simulation results show that the mass can be effectively optimized to meet the inertia mass ratio constraint of the first-stage, and the separation of Mach number and altitude can be optimized at the same time.
