way 5.2 EQCLPMENT 2D RECLNTRY PROCESLRES 5.2.1 Introductioa The sampling elements which were to have been carried to Teak burst al- titude are housed in mose cones having the same external configurations as those carrying instrimestation and are propelled by the sae type rocket motors. Unfortunately, both rad-chew rockets on Teak went unstable at the approximate tine of second-stage burnout, broke up, and fell into the sea about one mile from the Launchers. The four sampler rockets fired on Orange flew their plannea trajectories and were recovered. They did not, harver, contain samples. In operation, just before the rocxet enters the radioactive cloud, the wind screen (the forward 2& inches of the nose cone) and two side-vent ports are ejected, exposing the sampling elements to the debris. At apogee the sampling elesents are enclosed ian a watertight compartment, and an RF homing beacon sod a flashing light are actuated. During descent the nose cone separates from the second-stage rocket motor and a paracbute is deployed to lower the nose cope to the sea. A search-and-recovery operation is theo initiated for the sampler noose cones as well as for the instrumentation nose cones. 8 5.2.2 Sampler Nose Cone The external configuration of the sampler nose cones is identical to that of the instrumentation nose cones (Fig. 5.7) and consists of a 2h-iach wind screen, a 25 1/2-inch main body, and a 5-inch aft parachute ring. The wiod screen is automatically ejected in flight ta expose the filter just before the rocket enters the radioactive cloud. The parachute ring contains the parachute which is packed in a doughnut-shaped container, two dye-oarker containers, and the flight-progracming junction box. be sain body contains two filters, a filter container having two separate watertight compartoents, sanpler-actuating mechanisas, a beacon transmitter antenna, a flashing light, two ejectable vent ports, a dye-aarker container, and a watertight compartment containing the renainder of the beacon aad flashing light components (Fig. 5.0). 137
