Abstract: A holder for an x-ray sensing device having a first retention member and a handle. The first retention member includes a back plate, a first retention guide, and a second retention guide. The first retention guide is connected with an end of the back plate and the second retention guide connected with an opposing end of the back plate. The first retention guide faces the second retention guide. The handle is connected with the first retention member. Preferably, the first retention member includes a retention stop on a front surface of the back plate and between the retention guides.

Abstract: A system for holding and aligning an x-ray sensing device is described. The system includes a holder for an x-ray sensing device and a ring guide adapter which is removably connected with the holder. The ring guide adapter forms first and second alignment members. The system also includes a rod which is removably connected with either the first or second alignment member of the ring guide adapter.

Abstract: An instrument for holding and aligning an x-ray sensing device is described. The instrument includes a ring guide having a sight for aligning the cone of an x-ray device with an x-ray sensing device and arm having a first end slidably engaging an adjustment cavity formed in the sight. The adjustment cavity forms at least one alignment groove. The instrument also includes a holder for holding the x-ray sensing device. The holder has a first retention member including a back plate, a first retention guide connected with an end of the back plate and a second retention guide connected with an opposing end of the back plate. The holder further has an upper retention stop connected with the back plate and between the retention guides. The first retention guide faces the second retention guide. The arm has a second end engaging the holder.

Abstract: A low drag ducted ram air turbine generator and cooling system is provided. The ducted ram air turbine generator and cooling system has reduced drag with respect to prior ram air turbine generator systems while extracting dynamic energy from the air stream during the complete range of intended flight operating regimes. A centerbody/valve tube having an aerodynamically shaped nose is slidably received in a fairing and primary structure to provide a variable inlet area. An internal nozzle control mechanism attached to the valve tube positions nozzle control doors to provide variable area nozzles directing air flow to the turbine stator and rotor blades to maintain optimum generator efficiency. An alternate embodiment includes an annular internal nozzle having interleaved panels to modulate the air flow to the turbine.
