The engine is equipped with water injection for NO x control. 4.1.3 High Pressure Turbine (HPT) The PGT25+ HPT is a high efficiency air-cooled, two-stage design. The HPT section consists of the rotor and the first and second stage HPT nozzle assemblies.
LIDAR sensors are capable of receiving multiple returns, some up to five returns per pulse. This means that a 30-KHz sensor (30,000 pulses per second) must be capable of recording up to 150,000 returns per second. The first return recorded by a LIDAR sensor is the first thing hit by a laser pulse.This could be a treetop, roof, ground point, or a bird in flight. When a laser pulse hits a soft target (e.g., a forest canopy), the first return represents the top of that feature.he first return recorded by a LIDAR sensor is the first thing hit by a laser pulse.

Normal Pulse Rate for Infants. The average pulse of an infant at birth is 140 beats per minute. A normal pulse rate for children under one year old ranges from 90 to 170 beats per minute. This decreases slightly throughout the child's first year, but pulse rates up to 170 beats per minute are considered normal.
