Safe was awarded a Phase II SBIR program by the U.S. Navy/NAVAIR to continue development of a Passive Anti-Resonance (PAR) vibration isolator system that will isolate an entire helicopter crew seat at its floor attachments. The PAR vibration isolator will adjust automatically to limit displacement during inputs near the resonance frequency. It will address and improve the health risks, discomfort, and pain of military aircrew brought on by whole-body vibration in helicopters. The MH 60S rotorcraft pilot/co-pilot seat has been selected as the target platform for the initial system design and demonstration tests. However, the PAR system can be easily adapted to other platforms and/or seat positions.
Safe was awarded a Phase I SBIR program by the U.S. Navy/NAVAIR to develop a device that can measure rotorcraft dynamics to support objectives for improving crash safety. Two of the program’s technical objectives include developing a software algorithm that effectively discriminates between normal flight and crash conditions and specifying a hardware and software architecture that strikes a good balance of trades for a practical solution.
Safe was awarded this program’s continuation effort of SBIR Phases I and II under the United States Navy’s Topic N101-026, “Multi-Axis Vibration and Habitability Improvement for Seated Occupants.” The unique vibrations and flight characteristics of the E-2C/D aircraft cause significant crew discomfort, distraction, fatigue, and even pain. Safe will develop a new seat that will incorporate magnetorheological technology to help isolate the occupant from aircraft-generated vibrations and will optimize seating angles.
Safe was awarded a Phase II SBIR program from the United States Army to develop a new, effective spall liner for combat vehicles. Safe’s new spall liner design will benefit vehicle occupants by protecting them from the hazardous conditions associated with combat, including head injury. Occupants of ground combat vehicles are at risk of head injury when the vehicle is attacked by an underbody blast and its violent motion causes the head to strike the interior. Occupants are also at risk from spall, fragments of material liberated from the interior wall of the vehicle by shock waves or overmatched threats. The design solution will be generally applicable for use in many armored ground vehicles, but it will not yet be specifically designed for integration into any particular vehicle. Safe’s design approach addresses all key technical requirements including head impact, ballistic, thermal, acoustic, and FST.
Safe was awarded a Phase II SBIR program from the United States Army to refine, ballistic test, and demonstrate Safe’s Phase I design for armor for a Mobile Missile Launcher. Rocket motor propellant can react violently when struck by bullets or fragments of exploding weapons. Therefore, the primary benefit of the armor will be to allow mobile missile launchers to have Insensitive Munitions behavior simply by applying armor panels at select locations, rather than the far-more-difficult endeavor to change propellant or redesign the rocket motor. Limiting the most-severe reaction type to only burning, as opposed to a more violent reaction such as detonation, should make the missile launcher much safer for soldiers to operate in hostile environments.
Safe was awarded a Phase I SBIR program by the U.S. Navy/NAVAIR to develop a thermoelectrically cooled seat cushion to improve aircrew mission endurance and effectiveness. Effective cooling will prevent heat stress by limiting mission durations and reducing the detriment to concentration on mentally demanding tasks that reduces mission effectiveness. Safe’s innovative design will also address complaints reported by aircrew over back pain, inadequate padding, and loss of sensation in the legs with existing seat cushions by distributing pressure more uniformly across the body.
Safe was awarded a Phase I SBIR program by the U.S. Navy/NAVAIR to develop a Passive Occupant Weight Relief (POWR) harness to lift the weight of the pilot’s survival vest and armor carrier off of the torso while operating the aircraft. Aircrew back pain is a significant factor affecting aircrew mission endurance and effectiveness and increasing costs for medical treatment and disability. A Design of Experiments (DOE) will be used to determine ability to balance upward load and aft load created by the harness. The POWR harness will not hinder egress and will not require any additional steps to egress.
Safe was awarded a Phase I SBIR program by the U.S. Navy/NAVAIR to address and improve the health risks, discomfort, and pain of military aircrew brought on by whole-body vibration in helicopters. Safe is developing a Passive Anti-Resonance (PAR) vibration isolator that will isolate an entire helicopter crew seat at its floor attachments. The PAR vibration isolator will adjust automatically to limit displacement during inputs near the resonance frequency.
Safe was awarded a program by the U.S. Navy/NAVAIR to produce 530 MH-60S Next Generation Gunner Seat Selectable Profile Energy Absorber (SPEA) production kits and 50 spare SPEA production kits, with tasks including fabrication, assembly, and source inspection.
Safe was awarded a Phase I SBIR program from the United States Air Force/Air Force Research Laboratory (AFRL) to develop a flexible system of powered rollers for cargo aircraft to increase efficiency and reduce airman injury during loading and off-loading of aircraft. The program designed a study demonstrating feasibility of integration of powered rollers onto cargo aircraft and produced initial designs for roller construction and total system architecture.
