Manufacturer of GSE for Carolina GSE, Inc / PilotJohn.com – Clyde Machines Expands Production Facility With a 35,000 Building Addition

Source: Area Development Online
Date: 7/2/2014

Clyde Machines Inc., a company that designs and manufactures aircraft ground support equipment, is expanding its production center in Glenwood,Minnesota, with a 35,000-square-foot building addition.

The company that manufacturers trailers, towbars, maintenance stands, crew and passenger stairs, baggage carts and other equipment for the airline industry plans to add 15 associates to its workforce. To assist the company with the expansion, the Minnesota Department of Employment and Economic Development approved a $200,000 low-interest loan from the agency’s Minnesota Investment Fund. The company plans to use the funding for the expanded facility and new equipment.

“Significantly increasing our investment in the Minnesota Investment Fund has helped dozens of businesses like Clyde Machines expand across our state, creating thousands of new jobs,” said Governor Mark Dayton. “I congratulate Clyde Machines on its success in Minnesota and for this important expansion that will create 15 new jobs in Glenwood.”

“Clyde Machines is a family-owned business that has built an international clientele over the past 50 years,” said DEED Commissioner Katie Clark Sieben. “The company is a Minnesota success story, and we welcome the opportunity to help them to build on that success with new jobs and a bigger facility.”

What is Soft Start on Aircraft Ground Power Units?

$
0
0

Soft Start on Ground Power Units – What is it and do I need this option?

This is a limiter that can be either added into the power cart during manufacturing or at a later date. It limits the output current of the unit and will allow the voltage to automatically decrease as more current is drawn from the unit.

Its purpose is to “soften” the inrush of current when the starter of a turbine engine is first engaged to protect the starter from being over torqued and the solenoid contacts from arcing. Starting current will be limited to approximately 1000 amps when using the “soft start”.

On inrush, the “soft start” drops the voltage as needed to limit the current to around 1000 amps in order to stay connected. As the engine spools up, the voltage will return to 28 volts. On some aircraft, the battery must be turned on in order to be able to inject external power into the start system. In this type of arrangement the aircraft batteries and power cart are in parallel. On a start, the engine draws power from both the batteries and the power cart. If the “soft start” is switched on the batteries will furnish about 80% of the power and the power cart about 20%. With the “soft start” switched in “normal” position, or out of the circuit, the reverse is true, 80% will come from the power cart and 20% from the aircraft batteries as it should. On aircraft where the start can be supplied from external, the power cart will supply 100% of the power.
