Deploying Unmanned Aircraft Systems (UAS) in safety- and business-critical operations requires demonstrating compliance with applicable regulations a comprehensive understanding of the residual risk associated UAS operation. To support these activities enable safe deployment into civil airspace, European Union Aviation Safety Agency (EASA) has established regulatory framework that mandates exec...

It is generally accepted that there are no absolute contraindications to the movement of patients by air (1, 2). However, there are special physical and physiological factors that must be considered before subjecting a patient to the potentially hostile flight environment. The major considerations are altitude and airframe whilst minor considerations include space, noise, vibration, turbulence,...

The Rolling Airframe Missile (RAM) provides the US and German Navies with a quick reaction, high firepower defense against Anti-Ship Missiles (ASM) such as the Exocet and SSN-22. RAM incorporates passive RF and IR sensors allowing track and guidance against both radiating and nonradiating threats. The "fire and forget" feature coupled with RAMs quick reaction protects ships against dense raids ...

The Missile, Research, Development and Engineering Center, MRDEC, of the U.S. Army Aviation and Missile Command, AMCOM is developing and demonstrating tele-operated missile systems that provide many of the capabilities that the Army has stated it needs. These capabilities include flexible mission planning, improved Identification Friend or Foe, minimum collateral damage, and precision hit. The ...

This paper presents the hardware design and integration process employed to develop an Unmanned Aircraft System (UAS) helicopter. The design process evolves from the bare airframe (without any electronics), to become a complete and advanced UAS platform for remote sensing applications. The improvements, design decisions and justifications are described throughout the paper. Two airframes have b...

Unmanned aerial vehicles (UAVs) present in a wide range of scales, airframe types and possible systems configurations. Assessing how these different systems perform, therefore, should be an essential part of their design. This task, however, is particularly difficult due to the complex, dynamic interactions these vehicles are capable of, and the often complex operational conditions. In this pap...

An aircraft system noise study is presented for the Blended-Wing-Body (BWB) aircraft concept with three open rotor engines mounted on the upper surface of the airframe. It is shown that for such an aircraft, the cumulative Effective Perceived Noise Level (EPNL) is about 24 dB below the current aircraft noise regulations of Stage 4. While this makes the design acoustically viable in meeting the ...
