NASA aeronautical programs require rigorous ground and flight testing. Many of the testing environments can be extremely harsh. These environments include cryogenic temperatures and high temperatures (greater than 1500°C). Temperature, pressure, vibration, ionizing radiation, and chemical exposure may all be part of the harsh environment found in testing. This paper presents a survey of research opportunities for universities and industry to develop new wireless sensors that address anticipated structural health monitoring (SHM) and testing needs for aeronautical vehicles. Potential applications of passive wireless sensors for ground testing and high altitude aircraft operations are presented. Some of the challenges and issues of the technology are also presented.I.

“…It is further suggested that, by including all the data necessary to make direct maintenance decisions within the sensor node rather than processing it centrally through other systems, wireless sensors can operate independently and reduce costs compared to timebased maintenance systems significantly. Bai et al [9] describe the architecture of a WSN for aircraft engine health monitoring, which comprises of a number of sensors and a central engine control unit. Its communication protocol stack includes a power-aware routing module, a node positioning module, a network membership module and a low-power media access module.…”

Wireless sensor and actuator networks: Enabling the nervous system of the active aircraft

The ever-increasing volume of air transport necessitates new technologies to be adopted by the flight industry to fulfil the requirements of safety, security, affordability and environment friendliness while still meeting the growing demand. What we need to achieve this goal is a new type of aircraft cruise control, interconnecting all the onboard active control systems and making more accurate control decisions than is currently possible, thus improving the overall flight efficiency. "Active Aircraft" envisions such a nervous system of distributed wireless sensor and actuator network (WSAN) components, enabling the early detection of potential problems, and quick, accurate reactions to these. As part of this vision, WSAN deployed on aircraft wings help the reduction of aerodynamic drag and significantly reduce fuel consumption.In this article, we first describe this conceptual change in aircraft control technology. We then introduce a WSAN application to reduce skin friction drag, and a network topology to enable it. In our application, WSAN form virtual flap arrays on the wings to measure the skin friction in real time, and to react using synthetic jet actuators, which suck and expel air on the wing to reduce the friction. The Active Aircraft vision imposes stringent performance requirements on the underlying WSAN communication algorithms. The medium access control and routing protocols, in particular, must meet the quality of service criteria set by active control applications. Thus, we also present the application characteristics of Active Aircraft and raise the issue of design considerations with regard to the communication protocols.

“…Research on energy harvesting (EH) has aimed to construct self-powered portable or wireless electrical devices (e.g., global positioning systems, wireless sensors) that use ambient, otherwise wasted, energy. As a result of the substantial research conducted in this field over the last two decades, current state-of-the-art devices can generate enough electrical power to operate wireless sensor nodes [1][2][3]. This EH technology is in high demand because wireless sensors are increasingly used in the areas of PHM (prognostics and health management) and/or building automation, and batteries can be troublesome due to their limited lifespan and high replacement 3 Author to whom any correspondence should be addressed.…”

This paper presents a design and experimental verification methodology for energy harvesting (EH) skin, which opens up a practical and compact piezoelectric energy harvesting concept. In the past, EH research has primarily focused on the design improvement of a cantilever-type EH device. However, such EH devices require additional space for proof mass and fixture and sometimes result in significant energy loss as the clamping condition becomes loose. Unlike the cantilever-type device, the proposed design is simply implemented by laminating a thin piezoelectric patch onto a vibrating structure. The design methodology proposed, which determines a highly efficient piezoelectric material distribution, is composed of two tasks: (i) topology optimization and (ii) shape optimization of the EH material. An outdoor condensing unit is chosen as a case study among many engineered systems with harmonic vibrating configuration. The proposed design methodology determined an optimal PZT material configuration on the outdoor unit skin structure. The designed EH skin was carefully prototyped to demonstrate that it can generate power up to 3.7 mW, which is sustainable for operating wireless sensor units for structural health monitoring and/or building automation.
