Enviado por Felipe Machini flag Denunciar. Sikorsky Aircraft Corporation . Of course, in parallel with building vertically flying machines and heli- copters, fixed wing aircraft started to evolve over the last one hundred plus years, with the first flight demonstrated by the Wright brothers in Focusing on unmanned fixed-wing aircraft, major breakthroughs hap- pened over the past thirty years; therefore, a new Section is devoted to summarize progress. Included in new era designs are also modern rotor- craft configurations.

It includes giant scale, large, small, miniature and mini scale UAVs compared to their manned counterparts , as well as airship models. Figures have been retrieved mostly from refer- ences ,  and .
Some of the most well known models are the ones being used by the military around the world. Their advantages over manned aircraft in terms of endurance due to pilot fatigue and expendability have been demon- strated and proven in recent conflicts.

It is capable of delivering munitions. It has been designed by Northrop Grumman . It is used mainly for reconnaissance . It is designed by Northrop Grumman and it has demonstrated autonomous flight capabilities . The next set of Figures, up to and including Figure 2.
Unmanned Aerial Systems (UAS)
Representative UAVs of this group are the Seagull- Elbit UAV that consists of a single wing carrying the fuselage over it, powered by a rear mounted propeller. Similarly, the Dragoneye by AeroViroment has no tail wings but maintains its tail rudder. The Sikorski Cypher II is a duct-shaped rotorcraft that also has fixed wings. The X experimental UAV explores the canard rotating wing configuration. UAVs that belong to this category are shown next.

The X aircraft built by Boeing Corp. The benefits of UAS are wide ranging and impact nearly all aspects of highway transportation—replacing boots on the ground, increasing accuracy, speeding up data collection, and providing access to hard-to-reach locations. UAS provide high-quality survey and data mapping that can be collected automatically or remotely. Large areas can be mapped relatively quickly in comparison to traditional survey and mapping practices.
Other uses include survey and imagery as part of emergency response events, where traditional surveying and mapping practices may be inadequate or sites impossible to access. UAS can supplement conventional activities, such as bridge safety inspection and routine construction inspection, to increase safety and collect data from otherwise unattainable perspectives.

UAS improve operations, construction, inspection, and safety by collecting data needed to design, build, and operate the highway system. Bridge inspection enhanced by UAS improves safety for the inspection team and the traveling public by reducing the need for temporary work zones and specialized access equipment, which can also be very cost effective.
UAS technology gives State departments of transportation DOTs a new perspective during incident response for roadway disturbances such as rockslides, avalanches, and floods, and for damage assessment following earthquakes, fires, and bridge hits. It allows States to obtain quality data to make better-informed decisions, all collected from a relatively low-cost platform.
A survey by the American Association of State Highway and Transportation Officials found that 36 States are already using high-definition cameras, LiDAR, and other sensors to enhance construction inspection, bridge inspection, and incident response operations.
