The objectives of the proposed effort are to develop a geotechnical investigation scheme and a design methodology for hardened underground structures. these are to be achieved by entending existing new austrian tunneling method(natm) techniques through theoretical modeling combined with… More

Deep basing facilities require that structures be protected against blast effects. inherent in this need is for the tunnel support system to be economically installed and capable of withstanding overstresses which may reach or exceed 1 kilobar. in order to more efficiently harden a structure, the… More

Recent treaty negotiations between the us and the ussr place limits on the size and locations of nuclear tests. these limits are perceived as potential inducements for the ussr to conduct hidden tests outside the treaty requirements. one method of secretly conducting tests would be to perform… More

Air Force bare base shelters are "minimal facilities" designed to be rapidly transported, easily erected, weather resistant, and able to withstand some level of protection against attack. Due to these requirements, structural design is ideally carried out through an optimization process where… More

Drilling has been an integral part of defense community weapons effects testing for over 40 years. Hard target defeat programs have required specialized drilling technology in the creation of test targets and in the monitoring of weapons tests, that canonly be accomplished by directional drilling. … More

UTD proposes to develop a low reaction force drilling system for use on micro-gravity environments based on UTD's patented Helical Drag Bit technology. The Helical Drag Bit is unique in that it self advances into the hole, and thus does not require a large reaction force. Drilling into the Martian… More

UTD proposes to develop a lightweight, tethered autonomous small diameter core drill capable of reaching 200 m in depth, and greater, and able to extract core samples for the determination of water and/or biological life forms. The significance of this research is the enabling of exploration for… More

Blood-sucking or haematophagous arthropods such as mosquitoes, ticks, and sandflies act as vectors of some extremely deadly and debilitating diseases such as malaria, dengue, yellow fever, sandfly fever, Japanese encephalitis, Q-fever, and tularemia. Thecurrent kit used by preventative medical… More

UTD proposes to develop a lightweight, tethered autonomous small diameter core drill capable of reaching 10 and even 200 m in depth. The proposed approach is consistent with the planetary protection requirements and can be used to extract intact and tailings samples for biological and geological… More

78585S Some regions inside a nuclear reactor are not inspected because they are not accessible with current technology. Limited-access Remotely Operated Vehicles (ROVs) such as "FireFly" have been successfully used in limited cases to inspect inaccessible areas of concern in the reactor. However,… More

The goal of this proposal is to develop an articulated connection system that allows conventional landing craft/cargo vessels, such as the Landing Craft Utility (LCU) 1600 Class, to be linked in a train for increased cargo transit speed. The proposed method allows the connection device to link… More
