Technical Committees

Through its Technical Committees, the AHS has gained a reputation as an organization to which the government, industry and the general public look for assistance, direction and leadership with respect to vertical flight aircraft.

Serving on an AHS Technical Committee is an excellent way to stay current on the state-of-the-art advances in your specific technical discipline, while interacting and sharing your expertise with others who possess the same professional goals and face similar challenges. Our Technical Committees are populated with a broad cross-section from across the community -- review the rosters of the technical committees (AHS members can access committee rosters with email and phone when logged in by clicking on commttee description) to decide if you could help advance the state-of-the-art of vertical flight technology.

Technical committees provide the AHS with timely, high quality technical information that is disseminated to the industry through our Annual Forum, at AHS-sponsored technical meetings, chapter meetings and at regional specialists' meetings.

Acoustics Committee
This committee studies component and full-system noise generation and propagation. Methods of internal and external noise alleviation through active and passive control are also investigated.

Advanced Vertical Flight Committee
This committee's purpose is to broaden the vertical fight technology base with emphasis on V/STOL concepts beyond the conventional rotorcraft area.

Aerodynamics Committee
This committee studies lift and external propulsion components and systems and their interaction; airframe aerodynamics; noise mechanisms; overall performance; and air loads.

Aircraft Design Committee
This committee coordinates Society activities on (a) overall aircraft, subsystem, and component design; (b) design technology, design criteria, and design synthesis; (c) interdisciplinary design considerations including performance, reliability, maintainability, weights, and economics; and (d) vulnerability and crash safety considerations. The Aircraft Design Committee also oversees the activities of the Icing ITT.

Avionics & Systems Committee
This committee studies avionics, armament, and other mission equipment, and human engineering subsystems synthesis, integration and design relating to aircraft missions.

Crash Safety Committee
This committee studies all aspects of rotorcraft crashworthiness technology including human tolerance to crash impacts, in-flight obstacle strike, cockpit delethalization, crashworthy fuel systems, ditching and post-impact flotation, energy absorbing components such as landing gears, subfloor structure, seats and restraint systems with associated design criteria formulation, analytical model development, testing, and system integration into a crashworthy rotorcraft design.

Crew Stations & Human Factors Engineering Committee
This committee studies operational environments and mission requirements for identification of the aircrew and maintainer vehicle interface issues that impact workload and mission success. This will include the study of integrated crew station design; control concepts; information transfer; display methodology; symbology and formats; automation and artificial intelligence concepts; prototyping of crew systems; and the interdisciplinary interface of crew systems with other vehicle systems.

Dynamics Committee
This committee studies aeroelasticity; mechanical stability, vibration characteristics and isolation; structural response to steady and unsteady aerodynamics and other loading, including: noise, gusts, landing, and criteria.

Handling Qualities Committee
This Committee studies flying qualities, stability and control, response modeling criteria, control systems, and ground and water handling.

Health and Usage Monitoring Systems (HUMS) Committee
Studies the application and benefits of helicopter Health and Usage Monitoring System technology. The emphasis is focused on the application of helicopter monitoring systems, and monitoring system technologies, that have the potential of providing reduced helicopter direct operating costs and enhanced safety.

Modeling and Simulation Committee
This committee provides focus on the use of manned simulation in support of rotorcraft engineering design, test and evaluation, and aircrew training. The primary orientation of the committee is toward effective scientific and engineering applications of manned flight simulation as opposed to facilities, per se.

Operations Committee
This committee works to enhance the effectiveness of civil and military vertical flight operations.

Product Support Systems Technology Committee

Propulsion Committee
This Committee studies powerplant and power transmission design and criteria including their interaction, airframe interface, operational environment, related accessories and subsystems with primary emphasis on the disciplines of thermodynamics, internal aerodynamics, dynamics and drive-system technology.

Safety Committee
This committee studies the application and benefits of technology and operational procedures in order to negate the safety critical hazards to commercial, private and military rotorcraft in worldwide operations.  Safety is considered both at the component reliability level and integrally at the level of the helicopter and its operations.

Structures & Materials Committee
This committee studies structures and structural research, analysis, and testing; design criteria and position loads; material and processing technology.

System Engineering Tools/Processes Committee
This committee seeks a better understanding or communication implementing Systems Engineering elements within the AHS International community. This includes management, application, processes, tools, or results which illustrate the precepts of Systems Engineering integration across the AHS technical areas.  Specific topics of interest can range from understanding and documenting of customer requirements and design through manufacturing and field support.

Test & Evaluation Committee
This committee studies testing of all operational aspects, e.g., availability, survivability, economics, interdisciplinary tests and procedures for aircraft and components--small scale, full scale or simulation.
