1998 Intrumentation Tests (TINT 1998)
The armored T-28 deployed to Ft. Collins-Loveland Airport (FNL), for two
weeks in June, 1998, for flight tests of new and refurbished research equipment.
New equipment included a Science Engineering Associates (SEA) data acquisition
system, a Droplet Measurement Technologies (DMT) liquid water probe, a
video recording system, a prototype Stratton Park Engineering Corporation
High Volume Particle Spectrometer Probe (HVPS), and two systems of electric
field meters mounted in underwing pods from the New Mexico Institute of
Mining and Technology (NMIMT). A newly refurbished Particle Measuring
Systems, Inc. (PMS) Forward Scattering Spectrometer Probe (FSSP), was also
flown for the first time.
In-flight guidance was available to the pilots from the ground, via
radio link with the CSU-CHILL S-band meteorological research radar. Six
research flights in small to large convective storms, in the vicinity of
the CHILL radar, were carried out within the two-week program.
Most of the equipment worked well, in some cases after some tinkering.
The NMIMT field meter pods proved to have a negative effect on aircraft
performance and handling and caused the facility to re-direct its efforts
to improve the T-28 electric field meter system. Plans to build pod
meters for the T-28 were changed and instead a 6th meter was added to the
system of 5 meters mounted at various locations on the airframe. Also,
the unrefurbished PMS OAP-2D-C two-dimensional particle imaging probe showed
erratic behavior, leading to a subsequent significant refurbishment.
