Since 2009, AMPT has completed over two thousand hot-fire tests over nearly two dozen programs. Highlights from our recent programs include:

In Space Engine 100 test program

NASA and Aerojet Rocketdyne

100 hot-fire tests | -4F to 90F Propellant Conditioning | Mission Vacuum
The In Space Engine 100 is a 500 N divert and attitude control engine developed by Aerojet Rocketdyne for a variety of NASA programs. The engine is being provided to Astrobiotics, Moon Express, and Deep Space Industries for lunar commercial use as well as various government deep space missions.


By demonstrating a high level of flexibility and responsiveness, AMPT achieved same-day modifications to engine instrumentation, feed system modifications, and hardware changes. AMPT’s relationship with local fabrication partners provided next day machined parts for quick turnover.

Exoatmospheric Kill Vehicle test program

Aerojet Rocketdyne and The Missile Defence Agency

1500 hot-fire tests | Mission Vacuum

The Alternate Divert Thruster is a 2 kN to 4 kN engine developed by Aerojet Rocketdyne for use in the Missile Defense Agency’s Exoatmospheric Kill Vehicle. EKV are capable of intercepting Intercontinental Ballistic Missiles in the exosphere, minimizing loss of life events and chance of target impact.


AMPT interfaced with several agencies and industrial partners, including Aerojet Rocketdyne, the Missile Defense Agency, Raytheon, and Boeing. This program included engine qualification followed by extensive failure review and a final qualification; in total, the program lasted eighteen months of nearly continuous six days a week testing. AMPT was proud to deliver industry leading flexibility and response time, executing day-of design modifications and engine hardware changeovers, and performing an average of seven tests daily after completion of failure review. AMPT completed hot-fire and water flow testing in parallel. 

DACS Engineering Services

Air Force Research Laboratory, Edwards AFB

Data Acquisition and Control System Upgrade for GOX/GH2/CH4 Testing
AMPT was the prime contractor in a major overhaul of a DACS system employed in rocket engine injector analysis. As prime, AMPT led the design, documentation, layout, and planning of the DACS system and collaborated with the facility engineers to ensure the platform was straightforward and upgradeable.


AMPT implemented a National Instruments cRIO based control system with a fully customized software suite, upgrading from a basic Programmable Logic Controller (PLC) to a fully customizable Field Programmable Gate Array (FPGA) based platform. This solution provided fast implementation, tighter synchronization, and faster control speeds. AMPT designed a custom graphical user interface to control and configure the test article streaming relevant data for the user. The facility upgrade was designed to be highly scalable and expandable, initially providing over 100 control channels and 100 acquisition channels.

Temperature Conditioning

Custom capability to meet customer needs

AMPT emphasizes flexibility and turn around time in all our contracts. We also seek to continuously improve our capabilities to meet customer desires. AMPT developed a propellant temperature conditioning system capable of maintaining target temperatures between –20F to 100F to better simulate in-space temperature conditions. Propellant can be conditioned within the run tank, the bleed tank, the run lines, and engine inlets, and can maintain target temperature to within +/- 2 F.


Providing this additional capability allows our customers to collect higher fidelity data that better matches real world performance. AMPT successfully exceeded customer expectations for performance and completed system installation within four months of contract assignment. AMPT seeks to continually add and improve system capability to provide the highest fidelity test data.
