2. AIAA High Speed Air Breathing Propulsion (HSABP) Technical Committee
The HSABP TC brings together experts in high speed air breathing propulsion, providing the opportunity to exchange research findings, ideas, disseminate knowledge, and network with colleagues from around the globe.
We leverage the application of mechanical design, fluid mechanics, thermodynamics, combustion, science and technology of systems that enable supersonic and hypersonic vehicle propulsion, including: ramjets and scramjets; combined cycle systems and Unsteady propulsion devices e.g. pulse detonation engines, rotary detonation engines, and pressure-gain combustion devices.
We work to advance high speed air breathing propulsion technology by: Developing and sponsoring technical sessions and other conferences of interest; Coordinating with other AIAA TCs and PCs and other technical societies to organize and promote joint sessions and activities; Facilitating communications and reviews, and by Offering professional courses, and giving awards and recognition for special achievements.
We also provide AIAA with authoritative technical opinions and public policy recommendations on subjects related to high speed propulsion technologies.

8. AIAA HSABP TC Past Courses
Pulse Detonation Engines
Numerical Propulsion System Simulation (NPSS): An Introduction
Course presented a comprehensive overview of air-breathing Pulse Detonation Engines and other Constant Volume Combustion (CVC) propulsion concepts, including detonation combustion theory, performance metrics, fuels and initiation systems, detonation physics research, technical challenges, and opportunities for development of PDEs.
CVC approach is recognized as having the potential to significantly impact multiple propulsion applications. The course will address how CVC technology can be integrated into a turbine engine through different architectures.
The objective of this course is to give attendees a working knowledge of the Numerical Propulsion System Simulation (NPSS) code and allow them to create and/or modify system models using this software tool.
Course was co-sponsored by AIAA Air Breathing Propulsion Systems Integration Gas Turbine Engines, and High Speed Air Breathing Propulsion Technical Committees

14. USA - X51 Program
X51b is an unmanned Mach 7, JP-7-fueled scramjet demonstrator.
X-51 WaveRider program is a consortium of US Air Force, DARPA, NASA, Boeing and Pratt & Whitney Rocketdyne.
Managed by Propulsion Directorate within USAF Research Laboratory (AFRL).
During flight demonstrations, a B-52 carries vehicle to altitude of ~50,000 feet and then releases it.
Initially propelled by an ATACMS solid rocket booster, X51b scramjet will take over at ~ Mach 4.5, and vehicle will accelerate to a flight speed near Mach 6.
Purpose of flight testing is to observe acceleration between Mach 4 and Mach 6

Reaction Engines, Ltd. (REL) is developing SABRE, a hybrid air-breathing / rocket engine, which represents a huge advance over LACE technology.
Through a synthesis of elements from rocket and gas turbine technology, SABRE evolved from liquid-air cycle engines (LACE) which have a single rocket combustion chamber with associated pumps, pre-burner and nozzle, utilized in air-breathing and rocket operational modes.

20. Nomination of New TC Members
The AIAA HSABP TC invites colleagues involved in research, development, teaching, and application of high speed air breathing propulsion to join us.
The nomination period is open on 1 August for terms starting in May of the following year. However, nominations may be submitted at any time, and are held until 1 August to be submitted. Nominees should be individual AIAA members, or be ready to join if appointed.
The HSABP TC has between 30 and 35 members. Nearly one-third of the members rotate off the committees each year, leaving six to ten openings per year.
The TC chairs work diligently to maintain a good balance in (1) appropriate representation to the field from industry, research, education, and government; (2) the specialties covered in the specific TC scopes; and (3) geographical distribution relative to the area’s technical activity. Young professionals, women, and international members are especially encouraged to apply.
