During Obangame Express 2015, Nigerian Forces Conduct Bilateral Visit, Board, Search, and Seizure Training Aboard the USS Spearhead
AUTHOR Kenan O’Connor During Obangame Express 2015, Nigerian forces conduct bilateral visit, board, search, and seizure training aboard the USS Spearhead. The Spearhead was deployed to the U.S. 6th Fleet area of operations to support the international collaborative capacity- building program Africa Partnership Station. 70 | FEATURES PRISM 6, NO. 1 Implementing the Design for Maintaining Maritime Superiority in Europe and Africa BY VICE ADMIRAL JAMES G. FOGGO III, USN, AND ERIC THOMPSON merica’s security interests have always extended beyond its own shores—and the U.S. Navy has always defended that security at home and abroad. From the earliest days of A the Republic, the waters of Europe and Africa have been critical to U.S. security. In 1775, John Paul Jones sailed into harm’s way with one of our first frigates—USS Bonhomme Richard—to defeat the British warship HMS Serapis. That pitched battle ended with the sinking of the Bonhomme Richard but also with the capture of the Serapis as an American prize. Later, in the early 1800s, Lt. Stephen Decatur fought numerous naval battles off North Africa against the Barbary pirates, most notably in Tripoli, Libya. Throughout the next century, the U.S. Navy played a key role in the defeat of Germany in World War I and World War II. During the Cold War, the Navy was on the front lines, meeting the challenges of the Soviet Union, and thus playing a key role in its ultimate defeat and dissolution. The waters of Europe and Africa are still critical to U.S. -

We make it fly. airbus.com Editorial Europe Needs More Pragmatism The elections to the European Parliament in May were beset with more paradoxes than they have ever been. The strongest party which will take its seats in the plenary chambers in Brus- sels (and, as an expensive anachronism, also in Strasbourg), albeit only for a brief period, is the Brexit Party, with 29 seats, whose programme is implicit in their name. Although EU institutions across the entire continent are challenged in terms of their public acceptance, in many countries the election has been fought with a very great deal of emotion, as if the day of reckoning is dawning, on which decisions will be All or Nothing. Some have raised concerns about the prosperous “European Project”, which they see as in dire need of rescue from malevolent sceptics. Others have painted an image of the decline of the West, which would inevitably come about if Brussels were to be allowed to continue on its present course. -

Abstract Effect of Interactional
ABSTRACT Title of thesis: EFFECT OF INTERACTIONAL AERODYNAMICS ON COMPUTATIONAL AEROACOUSTICS OF SIKORSKY'S NOTIONAL X2 PLATFORM Ian Kevin Bahr Master of Science in Aerospace Engineering, 2020 Thesis directed by: Professor James Baeder A. James Clark School of Engineering Department of Aerospace Engineering An in-house acoustics code, ACUM, was used in conjunction with full vehicle CFD/CSD coupling to create a computational aeroacoustic framework to investigate the effect of aerodynamic interactions on the acoustic prediction of a compound coaxial helicopter. The full vehicle CFD/CSD was accomplished by using a high- fidelity computational fluid dynamics framework, HPCMP CREATETM-AV Helios, combined with an in-house computational structural dynamics solver to simulate the helicopter in steady forward flight. A notional X2TD helicopter consisting of a coaxial rotor, airframe and pusher propeller was used and split into three simulation cases: isolated coaxial and propeller, airframe and full helicopter configuration to investigate each component's affect on the others noise as well as the total noise. The primary impact on the acoustic prediction was the inclusion of the airframe in the CFD simulation as it affected both coaxial rotors as well as the propeller. It was found that the propeller and coaxial rotors had negligible impact on each other.

We suggest that readers contact the specific government and military programme offices if seeking to confirm the reliability of any data. 1 MARKET OVERVIEW Broadly speaking, the global helicopter market is currently facing a two- pronged assault. The military helicopter segment has been impacted significantly by continued defense budgetary pressures across most traditional markets, and a recent slide in global crude oil prices has impacted the demand for new civil helicopters as well as the level of activity for existing fleets engaged in the offshore oil & gas exploration sector. This situation has impacted industry OEMs significantly, many of which had been working towards strengthening the civil helicopter segment to partially offset the impact of budgetary cuts on the military segment. However, the medium- to long-term view of the market is promising given the presence of strong fundamentals and persistent, sustainable growth drivers. The market for military helicopters in particular is set to cross a technological threshold in the form of next-generation compound helicopters and tilt rotorcraft. -

Rotorcraft (2011)
Rotorcraft Overview The rotorcraft industry produces aircraft, powered by either turboshaft or reciprocating engines, capable of performing vertical take-off and landing (VTOL) operations. The rotorcraft sector includes helicopters, gyrocopters, and tiltrotor aircraft. Helicopters, which employ a horizontal rotor for both lift and propulsion, are the mainstay of the industry. Gyrocopters are produced in much smaller quantities, primarily for use in recreational flying. Tiltrotor aircraft, such as the V-22 Osprey1, can take off vertically and then fly horizontally as a fixed-wing aircraft. Rotorcraft are manufactured in most industrialized countries, based on indigenous design or in collaboration with, or under license from, other manufacturers. Manufacturers in the United States of civilian helicopters include American Eurocopter, Bell, Enstrom, Kaman, MD Helicopters, Robinson, Schweizer (now a subsidiary of Sikorsky), and Sikorsky. Bell moved its civilian helicopter production to Canada, with the last U.S. product completed in 1993.2 American Eurocopter—a subsidiary of the European manufacturer and subsidiary of EADS NV—has manufacturing and assembly facilities in Grand Prairie, Texas and Columbus, Missouri. European producers include AgustaWestland, Eurocopter, NHIndustries, and PZL Swidnik. Russian manufacturers including Mil Moscow, Kamov and Kazan helicopters, as well as a number of other rotorcraft related companies, have been consolidated under the Russian government majority-owned OAO OPK Oboronprom.3 (See this report’s Russia -
Design and Performance of Lift-Offset Rotorcraft for Short-Haul Missions
Design and Performance of Lift-Offset Rotorcraft for Short-Haul Missions Wayne Johnson Aeromechanics Branch National Aeronautics and Space Administration Ames Research Center, Moffett Field, California [email protected] Alex M. Moodie and Hyeonsoo Yeo Aeroflightdynamics Directorate (AMRDEC) U.S. Army Research, Development, and Engineering Command Ames Research Center, Moffett Field, California [email protected], [email protected] ABSTRACT The design and performance of compound helicopters utilizing lift-offset rotors are examined, in the context of short-haul, medium-size civil and military missions. The analysis tools used are the comprehensive analysis CAMRAD II and the sizing code NDARC. Following correlation of the comprehensive analysis with existing lift-offset aircraft flight test data, the rotor performance model for the sizing code was developed, and an initial estimate was made of the rotor size and key hover and cruise flight conditions. The rotor planform and twist were optimized for those conditions, and the sizing code rotor performance model updated. Two models for estimating the blade and hub weight of lift-offset rotors are discussed. The civil and military missions are described, along with the aircraft design assumptions. The aircraft are sized for 30 passengers or 6600 lb payload, with a range of 300 nm. Civil and military aircraft designs are described for each of the rotor weight models. Disk loading and blade loading were varied to optimize the designs, based on gross weight and fuel burn. The influence of technology is shown, in terms of rotor hub drag and rotor weight. and the rotor efficiency and lift capability steadily INTRODUCTION. -
