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.

THE FACTS. The normal resting heart rate for an adult ranges from 60 to 100 beats per minute. But some researchers believe it may be time to re-examine whatâs considered normal. Researchers have found that a resting pulse at the upper end of ânormalâ may indicate a higher risk of stroke and heart disease.HE FACTS.
