After years of promoting travel to and from Dulles International Airport, the Washington Dulles Task Force is turning its attention to its crowded cousin, National Airport.

The Metropolitan Washington Airports Authority has awarded the task force a $200,000 contract to work on facility improvements at Dulles and National. This contract has prompted the private, nonprofit group to broaden its charter and change its name to Washington Airports Task Force.

"We are trying to make the best use of both airports we can," said Thomas G. Morr, president of the task force. At Dulles, that means "attracting more international flights and encouraging more passengers to use the airport," he said. "At National, we are trying to improve service to the passengers who choose to use that airport."

Over the next five to seven years, the airports authority is investing about $1 billion to renovate everything from terminals and parking areas to bathrooms at both airports. Under the contract, the task force will conduct a survey of public opinion about what improvements are needed at the airports and explain construction projects to travelers. It is distributing brochures and presenting video and slide shows to ease passengers through the construction period.

"It will be most painful at National because of the limited space," Morr said. "Dulles' projects should not disrupt passengers too much, except for those using the midfield runway."

The original mission of the task force, when it started as the Dulles Policy Task Force in 1981, involved a cap that was declared on growth at National. After a ceiling was put on the number of flights at National in December of 1981, the task force set out to make Dulles a more popular and successful airport.

"The business community was concerned about Dulles because it had so few departures compared to National," Morr said. "Passengers had no choice about which airport to use. The airports themselves, which were federally owned and operated, could not advertise, because the government is forbidden from competing with the private sector."

The task force found a niche in marketing that airport to airline executives and travel agents. Its original goal -- to double the number of passengers from 2.1 million to 4.2 million a year by the end of 1985 -- was met in August of that year. Now Dulles has more than 11 million passengers a year and 300 departures a day.

"We were not the sole cause of this growth, we were a catalyst," Morr said. "We made the airline community aware of the changes occuring in the Washington metropolitan area."

Exhibition Marketing and Management Co. Inc., a McLean-based consulting firm, has a $2.25 million contract from the Soviet Union to stage a Soviet cultural exhibition in six U.S. cities. The exhibition, called "U.S.S.R.: Individual, Family, Society," is the result of a 1985 Geneva Summit pledge by the Soviet Union to take part in a cultural exchange with the United States. The show is to include 1,000 display booths, fashion shows, folk dancing and discussions with prominent Soviet citizens.

Exhibition Marketing is providing "everything the Soviets require, from promotion, transportation and electronic equipment to Customs clearances and security needs," said David Wolstenholme, president of the company.

"The only difficulty with the project was trying to convince the Soviets that funds were needed for advertising," Wolstenholme said.Exhibition Marketing circumvented the problem by calling schools in the area to encourage students and parents to attend.

In spite of having no advertising budget, the exhibition drew 72,000 people when it opened in New Orleans in August. The show is coming to the Departmental Auditorium at 1301 Constitution Ave. in the District.

R.M. Vredenburg & Co. of McLean is monitoring the costs and progress of the Navy's torpedo program under a $7.8 million contract with the Naval Sea Systems Command.

The firm has supported the Navy's advanced lightweight torpedo program since 1976.

Global Trade is collecting trade information on a data base that will track trade laws, export and imports flows, and balance of trade statistics around the globe. "We are trying to combine the traditional merchant banking role with computer capabilities," McKinn said.

Technica will become AMS' credit analysis group. Paul A. Makowski and Steven C. Mutschler, cofounders of Technica, have been named managing officers of the new group. It will move its headquarters from New Jersey to Arlington next year.
