The Army is launching a Long-Range Hypersonic Weapon program to develop a capability to punch through
contested, anti-access environments - a big-ticket acquisition project that will re-purpose a Navy hypersonic
booster being developed by Lockheed Martin for use on a road-mobile system, giving ground forces a
conventionally armed strategic system for the opening salvos of a major fight. On Oct. 4, the Army presented
secret plans for this new deep-strike weapon to a select industry audience, setting in motion an...

For reference on the intermediate range booster stack:

Quote
SSP seeks input from industry to determine if there are sources capable of satisfying its potential requirements
to design two Technology Booster Solid Rocket Motor stages. The booster should use high energy Hazard Class 1.3
propellant, be capable of Intermediate Range, and in the 30 to 40 inch diameter class. The anticipated primary
deliverables are a Technology Booster Design Disclosure, a Performance Analysis and Design Report, a Technology
Booster Demonstration Static Firing Test Plan and associated Post-Test Analysis Report.

The potential booster design, build, and ground test does not reflect any endorsement by the Department of Defense
nor does it reflect any policy considerations that may apply to any given concept (e.g., basing arrangements, treaty compliance, etc.)

From March of 2017; that last chunk on treaty compliance is cute.

Program Targets Innovative Propulsion Solutions for Ground-Based Weapons Delivery System


Quote
The joint DARPA/U.S. Army Operational Fires (OpFires) program will soon kick off with three performers awarded contracts to begin work: Aerojet Rocketdyne, Exquadrum, and Sierra Nevada Corporation. OpFires aims to develop and demonstrate a novel ground-launched system enabling hypersonic boost glide weapons to penetrate modern enemy air defenses and rapidly and precisely engage critical time sensitive targets.

OpFires seeks to develop innovative propulsion solutions that will enable a mobile, ground-launched tactical weapons delivery system capable of carrying a variety of payloads to a variety of ranges. Phase 1 of the program will be a 12-month effort focused on early development and demonstration of booster solutions that provide variable thrust propulsion across robust operational parameters in large tactical missiles.

“OpFires represents a critical capability development in support of the Army’s investments in long-range precision fires,” says DARPA’s OpFires program manager, Maj. Amber Walker (U.S. Army). “These awards are the first step in the process to deliver this capability in support of U.S. overmatch.”

The OpFires program will conduct a series of subsystem tests designed to evaluate component design and system compatibility for future tactical operating environments. Phase 2 will mature designs and demonstrate performance with hot/static fire tests targeted for late 2020. Phase 3, which will focus on weapon system integration, will culminate in integrated end-to-end flight tests in 2022.

DESLA Team Successfully Tests Thrust Chamber and Nozzle Technologies Key for Advanced Upper Stage Engine

VICTORVILLE, CA – November 1, 2012 The DESLA Team, which is comprised of Exquadrum, WASK Engineering, and ATK (NYSE: ATK), announce they have successfully conducted testing on a modular thrust chamber design and aerospike nozzle as part of AFRL research efforts. The data gathered on these programs will be leveraged for the Dual Expander Short Length Aerospike (DESLA) engine.

Exquadrum conducted a series of full-scale hot fire tests up to 100 percent chamber pressure on the modular thrust chamber funded under the Deep Throttle Enabling Nozzle Technology SBIR contract at its Adelanto, California test facility. The modular thrust chamber enables modern manufacturing methods that significantly lowers recurring and non-recurring costs, which are necessary to achieve an affordable engine while enhancing overall system performance.

“The successful testing of the modular thruster demonstrates both the performance and significant cost savings this technology provides," said Philip Pelfrey, Executive Vice President for Exquadrum.

Additionally, WASK Engineering has successfully completed baseline performance cold flow testing of a 30 percent length annular aerospike nozzle from sea level to vacuum conditions as part of the Third Generation Reusable Boost (3GRB) Program at the NASA Marshall Space Flight Center Nozzle Test Facility in Huntsville, Alabama. The testing obtained high quality data that validated computer tools and performance predictions which will be used for the DESLA engine.

“The results of this testing effort validated the performance predictions for the nozzle technology we are using for DESLA”, said Wendel Burkhardt, President of WASK Engineering.

The DESLA engine is an advanced, 30,000 pound thrust liquid hydrogen / liquid oxygen upper stage engine intended for the Air Force’s Evolved Expendable Launch Vehicle (EELV) and NASA’s next generation Cryogenic Propulsion System (CPS).

AFRL has awarded Exquadrum a nine month contract to develop a novel upper stage engine cycle. In performance of the contract, Exquadrum will further develop its SLATE dual-bleed expander cycle engine conceptual design and conduct proof-of-concept demonstration testing. The SLATE engine enables lower pump discharge and system pressures for high-reliability and reduced weight.

The goal of the program is to reduce the weight and cost of the upper stage rocket engine while maintaining state-of-the-art performance and increasing reliability, operability, and scalability. Exquadrum’s upper stage rocket engine concept is significantly smaller and lighter than historical engines, is scalable to larger thrust levels, and promises increased stability over any existing conventional thrust chamber of comparable engine size.

Contract leverages company’s expertise in hypersonic technology
Goal is to develop a mobile, long-range weapon that could engage time-sensitive targets
Design work could lead to hardware development and testing

HUNTSVILLE, Ala., Dec. 11, 2018 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne will design propulsion concepts and
technologies for a novel ground-launched tactical weapon system under a U.S. Defense Advanced Research Projects
Agency (DARPA) contract potentially valued at $13.4 million.

DARPA’s Operational Fires, or OpFires, program seeks to develop a mobile missile system that would be capable of
delivering a variety of tactical payloads to different ranges that could rapidly and precisely engage time-sensitive targets.
The program will leverage and integrate ongoing investments being made in hypersonic tactical boost glide vehicles.

“We are very pleased to have been selected by DARPA to develop propulsion technologies to support the OpFires
program,” said Eileen Drake, CEO and president of Aerojet Rocketdyne. “Our innovative team has a tremendous amount
of experience developing hypersonic and missile technologies, such as solid rocket booster motors, divert and attitude
control systems, warheads and scramjet propulsion systems. We look forward to applying our experience to the OpFires
program.”

The first phase of the OpFires program is focused on the design and development of an advanced solid rocket motor and
is valued at $4.6 million over a 12-month period. The award contains an option for Phase 2, under which Aerojet
Rocketdyne would build and test at least two representative booster test articles. That option, if exercised, would be
worth $8.8 million over 12 month

DARPA pursues materials, architecture to cool hypersonic vehicles



Quote
To address the challenge DARPA has initiated the Materials, Architectures, and Characterization for Hypersonics (MACH) programme. The programme seeks to develop and demonstrate new design and material solutions for sharp, shape-stable, high heat flux capable leading edge systems for hypersonic vehicles travelling more than five times the speed of sound.

DARPA is seeking expertise in thermal engineering and design, advanced computational materials development, architected materials design, fabrication and testing (including net shape fabrication of high temperature metals, ceramics, and their composites), hypersonic leading-edge design and performance, and advanced thermal protection systems. DARPA has specified that it does not want research “that primarily results in evolutionary improvements to the existing state of practice”.

The MACH programme will comprise two technical areas. The first area aims to develop and mature a fully integrated passive thermal management system to cool leading edges based on scalable net-shape manufacturing and advanced thermal design. The second technical area will focus on next-generation hypersonic materials research, applying modern high-fidelity computation capabilities to develop new passive and active thermal management concepts, coatings, and materials for future cooled hypersonic leading edge applications.

Bill Carter, Program Manager in DARPA’s Defense Sciences Office (DSO), said, “For decades people have studied cooling the hot leading edges of hypersonic vehicles but haven’t been able to demonstrate practical concepts in flight.

“The key is developing scalable materials architectures that enable mass transport to spread and reject heat. In recent years we’ve seen advances in thermal engineering and manufacturing that could enable the design and fabrication of very complex architectures not possible in the past. If successful, we could see a breakthrough in mitigating aerothermal effects at the leading edge that would enhance hypersonic performance,” he added.

The DSO will convene a Proposers Day meeting on 22 January 2019 to advise potential proposers on the objectives of the MACH programme.

Aviation Week reports that the schedule for DARPA/USAF Tactical Boost Glide has moved from late-June 2019 to December 2019 owing to "technical challenges" and  this along with delays in FY18 funding/awards have pushed the ARRW pre-design review and a flight test of the first instrumented measurement vehicle to this summer (should have been done by now) since ARRW apparently shares the glide vehicle with DARPA's TBG. HCSW which apparently uses the the "Swerve" inspired vehicle is on track for a December 2020 flight test with PDR scheduled for this June with a CDR for next March.

If we'd actually stuck to it in the past, instead of quitting at the first sign of difficulty, we might not be having these "technical challenges" right now.
