Recent Projects

We love to get our hands and feet wet in a variety of projects ranging from race cars to unmanned aircraft and everything in between. Some of our most recent projects include:


As part of a NAVAIR Phase II SBIR, HF Designworks and ThayerMahan have developed FortiFly, a next generation aviator training tool. Through AI-teaming; understanding, use, and trust in automation; and proprietary real time workload measurement FortiFly can elevate pilot skills for tomorrow’s missions; today.

Navy VTOL Family of Systems for Future Vertical Lift

HF Designworks is leading an effort supporting the Navy’s Future Vertical Lift (FVL) Vertical Take-off and Landing (VTOL) Family of Systems (FoS). Through the use of workload modeling, simulation training, and automation we are building a Learning Management System to help future aviators better understand and effectively use artificial intelligence as it applies to the needs of next generation Navy missions and beyond.

Eagle Cap Aero Charting

Supported Eagle Cap Software with the design of their Aero Charting iOS application (now available on Apple’s App Store). This application allows general aviation pilots to create and chart their flight routes over various maps and overlays.

Army Future Vertical Lift (FVL)

HF Designworks is supporting the FVL effort through identifying best of breed technologies and automations as well as developing human performance models to test and evaluate these technologies and automations to help determine optimal crew configurations.

Resource Central

HF Designworks has been working with Resource Central assisting with their Slow The Flow water conservation program. We have developed an interface for auditing customer water usage as well as an online calendar system for scheduling appointments.


HF Designworks has supported NASA’s Dryden Flight Research Center in meeting the goals of the Unmanned Aircraft Systems Integration in the National Airspace System, aka UAS in the NAS. This effort seeks to fill key gaps in the current NASA research and technology portfolio in the areas of modeling and simulation, separation assurance and detect and avoid, systems analysis, certification and test techniques for unmanned aircraft systems. Current Federal Aviation Administration safety of flight rules and certification standards were written with the assumption of having a pilot aboard the aircraft. These standards limit operation of unmanned aircraft systems in the national airspace. The goal of NASA’s UAS in the NAS project is to reduce technical barriers related to the safety and operational challenges associated with enabling routine access for unmanned aircraft systems to the NAS. As part of this effort, HF Designworks reviewed the latest UAS advances, exploring advanced waypoint navigation and autopilot technologies, as well as detect and avoid auto resolver type algorithms.

Location Based Critical Information Reporting

Leveraging Natural Language Processing (NLP) and HF Designworks’ own analytic algorithms, we built a system that scoured through social media and news outlets to extract needle in a haystack news stories of proximal- and preference-based importance to end users.

Army Corps of Engineers CREATE

HF Designworks developed the Cultural Reasoning and Ethnographic Analysis for the Tactical Environment (CREATE) tool. CREATE helps users visualize relationships between data using factors such as location, name, organization, affiliations, interests, etc.

iWarrior and Transformative Applications

Starting with a Phase I effort and culminating with a Phase II enhancement effort, and now looking at commercialization opportunities, HFDW developed iWarrior, a web based information visualization tool for commanders. iWarrior supports human behavior analysis, situation awareness, and mission planning by leveraging historical GPS data and presenting it to commanders in an easy to understand manner. Visualizations include playback of missions, mission notes, and importantly, statistics and heat maps which identify patterns in travel/patrol behaviors used for preventing insurgents learning coalition force techniques. Features of iWarrior have been transferred to other programs including Blox, Response Force, and Transformative Applications (HFDW has developed two Android mobile applications under the Transformative Applications program; MyHeatMaps and TransCalendar). Components of our products as well as entire in-house HF Designworks developed applications have seen use in Iraq (U.S. Army), Afghanistan (U.S. Army), Presidential inaugurations [by the Department of Homeland Security (DHS)], and Boston Marathons (DHS). As part of an internal commercialization effort, HF Designworks has also developed these heat maps to be used by UAS (leveraging data provided by local UAS manufacturers) to show areas of travel for sensor optimization and fuel efficiency.
