Abstract Fluid power system design is a skilful and complex task requiring significant practical experience and heuristic knowledge gained over many years. Industries specifying and/or designing fluid power systems in their products are at risk should they lose key personnel with this knowledge. This problem is compounded by a lack of formal training at the graduate level, creating a shortfall in qualified fluid power designers. Design support tools that assist and guide designers in their work, as part of a Concurrent Engineering approach, should be capable of providing both good practice guidance and a framework into which product specific information can be stored for later reuse. This paper discusses the early development of a fluid power system design tool that seeks to offer this support using a methodology developed in hypermedia.

This manuscript discusses the operation of an electrically driven fan for a hybrid-electric propulsion system for BAe-146 aircraft. The thrust requirement is fed into an integrated cycle and aerodynamic design tool for the sizing of a ducted fan as one of the main propulsors, podded under the wing as a replacement for a turbofan engine. The electric motor design is initiated with the torque and speed requirements and with the dimensional constraints arising from the driven fan geometry. The fan operation and aerodynamic design are derived by changing the fan pressure ratio and hub-to-tip ratio to obtain a 2-D design space. Surface-mounted permanent magnet electric motor designs are mapped on the 2-D fan design space. The design and operational flexibility of the system is investigated through three scenarios. In the first scenario, the aircraft rate of climb is changed to downsize the electric motor. In the second scenario, the electric motor rated frequency is changed to increase the power density and in the third scenario the electric motor current density is changed for the same purpose. The investigated three scenarios provide design and operational guidelines for reducing the weight of the electric motor for a direct drive application.

A car accident while parking the car is caused by the car driver, who is invisible around the car. However, there are no solutions for parking assistance when the driver is outside the car. The objective of this paper is to propose a reconfigurable embedded system design by voice controlled parking assistance system for a prototype electric vehicle connected to a smartphone via Bluetooth. Hardware and software co-design using the Xilinx VIVADO as a software design tool is introduced. We design the hardware and software on an ARM multicore processor and the reconfigurable system board model ZYBO: XC7Z010 by considering it as hardware accelerator. The hardware of the proposed voice controlled exterior car parking assistance system is installed on the miniature electric vehicle. The experiments are tested successfully at the parking area for both reverse parking and reverse parallel parking. This proposed system is better suited for users so that they can control their car comfortably while parking safely.
