Honeywell Green Jet Fuel Powers the First Single-Engine Turboprop Flight

Honeywell’s Green Jet Fuel™ was used to power the first single-engine turboprop flight on a Texas Turbines Conversions, Inc.-operated Cessna Caravan 208B at EAA’s 2012 AirVenture air show in Oshkosh, Wisconsin.  The aircraft’s Honeywell TPE331-12JR turboprop engine was fueled with a 50/50 blend of petroleum-based fuel (Jet A) and Green Jet Fuel made from the inedible plant camelina, which met all of the specifications for Jet A fuel and did not require any modifications to the aircraft or engine. 

Based on life-cycle analyses, during the flight from Texas Turbine’s headquarters in Celina, Texas to Oshkosh, the fuel provided a net reduction in greenhouse gas emissions of 34% compared to pure Jet A. 

Texas Turbines retrofitted the Cessna Caravan 208B with the 900 SHP Honeywell TPE331 engine to provide substantially improved performance for climb, speed or cruise fuel burn compared to the current production Caravan.  This retrofit is certified for both the Caravan 208, Grand Caravan 208B and is certified for wheels, floats and flight-into-known-icing (FIKI).

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
