1. CHALLENGE CHOICE

Aircraft industry challenge is to develop efficienty aircrafts, which should have competitive features and ensure harmony between systems and enviroment. In this way, fly-by-wireless challenge shows a bias required for enchancement of aircrafts systems, in where wires reduction and sequente weight reduction presents a key point for a chain reaction of improvements in several aspects.

2. SOLUTION DEFINITION

Proposed system apresents significant reduction in number of wires and fulfil the following prerequisites:

- Low Weight;

- Reliability;

- Safety and security;

- High data transmission capacity.

Solution operate in three systems different adopting fly-by-light and fly-by-wireless technology. Chosen system were: flying command system, entertainment system e replacement of some sensors.

For flying command and entertainment systems, fly-by-light tech fits perfectly, replacing wires by optical fibers. This way, we get a decrease of about 25% in system width and 50% in weight, increasement in reliability, upon non existence of eletromagnetic interference, higher data transmission rate and capacibility. The proposed fiber will be constructed with Bragg sensors in order to reduct electro optical converters, resulting in a less expensive data transmission method.

Replaced sensors will be ice detector and measurements of fuel volume and cabin internal and external temperature. In which, we will use fly by wireless technoly with passive and ative sensors.

Thereby, presented solution impacts into the aincraft will be higher flying range and autonomy, lower fuel consumption and, therefore, lower pollutants emission. Furthermore, as aircrafts tendency is to use more composites materials, structure do not give a electromagnetic protection, which can be scorned using fiber optic solution. Moreover higher data transmission rate means aircrafts can fly faster.

3. LOOKING TO THE FUTURE

Solution can be developed in order to fit spacecrafts prerequisites, because it can generate the same benefits of aircrafts. Aligning introduced system with NASA proposes for wireless avionics and electrical atuator, the final result will be wires reduction, as well as hidraulic systems reduction, which means a higher weight reduction.
