The 8.5 kW of power available for research <br /> <br />purposes~ and divided up as indicated in Table l.l~ is monitored and controlled <br /> <br />from a distribution panel in the forward cabin. The panel contains a master <br /> <br />switch enabling the pilot to switch off all research instrumentation. This <br /> <br />system for the electrical wiring has proven to be very convenient and permits <br /> <br />rapid changes in the instruments and equipment. <br />A number of research instruments need to be located well away from the <br /> <br />region of disturbed air around the fuselage. For this purpose two bomb racks <br /> <br />were attached under each wing and well removed from the fuselage. Each rack <br /> <br />can support a load up to 70 kg. In addition, a substantial pylon and <br /> <br />shackle assembly was installed on the belly on the plane forward of the wings. <br /> <br />This can take a load of 230 kg and will accept any standard military fuel <br /> <br />tank into which large instruments can be mounted. <br /> <br />1.3 Research Instrumentation System <br /> <br />1.3.1 Instruments and Data Recording <br /> <br />The location of the research instruments on the B-23 aircraft are <br /> <br />indicated in Fig. 1.2. Detailed specifications on all of the instruments are <br />given in Table 1.2. These instruments give us the capability of tracing cloud <br />microphysical processes from nucleation through to the production of <br />precipitation particles. Fig. 1.3 and Table 1.3 contain information on the <br /> <br />methods which are used for recording and displaying the data. The data <br /> <br />recording system is a combination of direct recording, PM recording, FM <br /> <br />multiplexing and time-share multiplexing. This system (which was developed <br /> <br />
