Three large U.S. manufacturers reported results that topped Wall Street’s expectations. It cited recovering demand in all aspects from corporate jets to equipment so they can run factories more effectively.

Rockwell Automation, Textron Inc, and United Technologies Corp posted increased gains in the recent quarter. They said they were growing more optimistic in the recovery of the economy, most especially in rising markets.

Scott Donelly, chief executive of Textron said they are chiefly motivated by the pick-up in the demand of business jets and commercial helicopters.  That reflects relative stability in global economies and improving confidence in general business.

Textron, which creates Bell helicopters and EZ-Go golf carts, is rising from an abrupt two-year slump in demand for corporate jets. They are expecting profits to grow more than three times this year as returns rise by about 11 percent.

Rockwell Automation sells machines and equipments to factory owners. They saw strong demand growth from rising markets and abruptly increased its profit forecasts for the year 2011.

The largest maker of elevators and air conditioners in the world United Tech said the demand for supplies to maintain air conditioning equipment and jet engines enhanced their results in the quarter.

Their sales increased to $14.9 billion, which is up to 6 percent. Both profit and sales topped the forecasts of the analysts. Textron reported fourth-quarter gain of 33 cents per share, except one-time items, leading the 25 cents that analysts had forecasted, Thomson Reuters said.

Rockwell informed their fiscal first-quarter profit was $150.1 million or $1.04 per share in comparison to year-earlier earnings of $76.6 million or 53 cents per share.

Thomson Reuters said analysts looked for a profit of 88 cents per share on average.
