SEPAC
Perfects Jet Engine Brake
|
SEPAC,
a clutch and brake company from Elmira, NY, used an engineering support program
funded by NASA to perfect a brake used on jet engines. The program offers 40 hours
of free engineering service. SEPAC has been developing new thruster-reverse brakes
to be used on Airbus' A380 jumbo jet, which will hit the skies in 2006. Airbus
has used SEPAC's brakes to hold the thrust reversers in place in the company's
jet engines. The thrust reversers work in combination with the A380's wheel-braking
system, slowing the aircraft on landing. Airbus asked SEPAC to reduce the weight
of its brake components without sacrificing strength and reliability. Thanks to
the NASA grant and with help from Design By Analysis, the company succeeded in
making the brakes thinner. More details can be found here.

Apollo
13's Unsung Heroes Receive First GlobalSpec Great Moments in Engineering Award
|
On Tuesday, April 19th, the GlobalSpec Great Moments
in Engineering Award was presented to NASA's Crew Systems Division (1970) at the
Space Center Houston.
This April marks the 35th anniversary of their heroic
efforts to bring the imperiled Apollo 13 safely home. The Crew Systems Division
showed engineering ingenuity and quick thinking under extreme pressure to conceive
and implement an in-flight modification to the environmental control system in
order to utilize the Command Module carbon dioxide absorbers in the Lunar Module.
Former Chief of Crew Systems Division, Ed Smylie accepted
the award on the team's behalf. Fred Haise, Apollo 13 astronaut, and TK Mattingly,
Apollo 16 astronaut, were also both on hand to celebrate the Crew Systems Division's
outstanding achievement. Click

Dear N.G.
Knear:
This is my first job and I love the company I'm working
for, the team of individuals I work with and believe it or not, even my manager.
So what's the problem? Unfortunately for me, my manager has been promoted to our
home office 1,000 miles away and we're getting a manager who is a stranger to
all of us. I feel like my mentor has been taken away. How do I get off on the
right foot with the new person?
Afraid of Change
Dear Afraid:
Sorry to break this to you, but change is going to happen. Good managers get promoted.
Some day, especially if you stay with the company, your former manager may have
a say in your promotion. Until then, it's important to remember that all good
managers want to help you succeed because your success means his or her success.
If you regard this new manager as a nemesis or try to compare him with your former
manager, you are setting yourself up for failure. One way to help both yourself
and your new manager is to be a "can-do person," the one your manager
can depend on. One key point to remember when you do a job and look good,
it reflects well on your manager. Good Luck!

New Engine-Braking
System Hits the Track
Ducati MotoGP team riders have been testing the motorcycle
company's new engine braking system. The new system is designed to optimize braking
stability by reducing excessive engine-braking forces and reducing fuel consumption.
In addition, the racers are also testing a new clutch system. While the new systems
may not be street-ready for a up to a year, you can see how the bikes are doing
at the Ducati racing site here.

Goldberg National Challenge 2005
For the third time in a row, the Purdue
Society of Professional Engineers again captured first place in the 2005 Theta
Tau Rube Goldberg Machine Contest.
This year's challenge was to remove both old batteries from a two-battery flashlight,
install new batteries and turn the flashlight on in at least 20 steps. The Purdue
machine was a hunk of vacuum tubes, cycle spokes, boxing gloves, wire tracks and
billiard balls. Take a look here.
