First CFM LEAP-1C engine powering C919 delivered to COMAC

CFM International has delivered the first LEAP-1C engine to the Commercial Aircraft Corp. of China (COMAC) for installation on the first C919.

The 150-seat aircraft was originally supposed to achieve first flight in 2014, but that has been pushed back to 2016. CFM and COMAC said the first C919 will roll out by the end of this year.

“Delivery of this engine paves the way for the final assembly and rollout of the first C919 aircraft later this year,” COMAC VP Wu Guanghui said in a statement. CFM and COMAC added, “C919 airplane development has entered a critical phase and final assembly of the first airframe structure is nearly complete. The wind tunnel test, iron-bird test, avionics integration and power system tests are all progressing well. With the delivery of the first LEAP-1C engine and the hydraulic systems, the installation of the airborne systems will begin soon.”

The LEAP family of engines was launched in 2009 when COMAC selected the 1C for the C919. The LEAP-1A will power the Airbus A320neo while the LEAP-1B is the sole-source engine for the Boeing 737 MAX. CFM EVP Allen Paxson said the first LEAP-1C “is the culmination of more than six years of hard work between the CFM and COMAC teams and represents the launch of the next exciting phase of the C919 aircraft development.”

Following on from the updates to its large frame 6R tractors, John Deere has updated its full line-up of 6M and 6R tractors.

Mainly driven by engine emissions compliance, all new 2016 models from 110 to 195hp will get Stage 4 power units using a combination of exhaust gas recirculation (EGR) and selective catalytic reduction SCR).

John Deere’s Craig Erskine explains: “These engines offer increased responsiveness over their predecessors and crucially have low AdBlue consumption – about 2 per cent of the fuel use.”

A new model, the 6195M, takes the 6M series to 195hp (206hp maximum). “This takes the design concept from the popular 7810, and offers more horsepower than the 8100, so we expect it to be a popular choice among stock farmers,” says Mr Erskine.

A new powershift transmission option, CommandQuad Plus, offers 20 by 20 or 24 by 24 speeds with Ecoshift mode and auto clutch.

Hydraulic system upgrades include an electronic loader joystick and the choice of four rear service valves or three with power beyond – new for this specification level – plus three mid service valves for the new R Series loader.

Statoil, Siemens develop subsea hydraulic power unit

MUNICH, Germany — Siemens and Statoil have jointly developed and qualified a subsea hydraulic power unit for use in offshore oil and gas fields in order to provide hydraulic power right at the well site.

The Subsea Hydraulic Power Unit (SHPU) supplies low pressure and high pressure control fluid to the subsea control modules. The subsea control module operates the hydraulic valves, the downhole safety valve and downhole chock/sliding sleeve. The hydraulic power unit can be used in the event that the umbilical fails and also as an alternative to the hydraulic lines in the umbilical. The power unit has successfully completed the qualification process, in which it has passed function tests under hyperbaric pressure equal to a water depth of 500 m.

The SHPU is an important building block in the industry-wide vision for a subsea factory, where the process plant is placed on the seabed. This unit was developed to be used as a contingency for an umbilical failure on a field in the North Sea. In addition to a repair function, the SHPU can also be used to extend the life-time of brown fields. For green field developments, especially in deep water and long step-outs, the SHPU can be a cost-efficient alternative to complex umbilical lines. The most significant advantage will be to replace hydraulic power transmission lines with local subsea hydraulic power generation and storage.
