Model Airplanes

With a population of close to 200 million people and rounding up to about 40 per cent of Africa’s population, Nigeria remains one of the world’s biggest aviation markets. In this report, SAMSON ECHENIM looks into the recent plan to concession the country’s four major international airports and other plans of the federal government to reposition the country’s aviation industry.

The aviation industry for nations is like the web that connects all other sectors of the economy to the engine room of the nations. It does not stop there. It also connects countries and continents, eliminating economic and physical boundaries and cementing successful business across the globe.

The contributions of aviation to the world’s super powers remain obvious and still very relevant to the sustenance of growth in those countries.

According to an industry report obtained from the aviationbenefits.org, air transport supports 36.9 million jobs and $656 billion in gross domestic product (GDP) in developing countries. The air transport industry in developing countries directly generated an estimated three million jobs in 2012, with airlines generating 789,000, which is 26 per cent of the total. Airport operators generated 299,000, indicating 10 per cent, while other on-airport services provided 1.5 million jobs reaching 51 per cent of the total job figure in developing countries. The civil aerospace took up some 299,000, about 10 per cent, leaving 95,000 to air navigation service providers, which filled up the remaining three per cent.

Including indirect and induced impacts, the air transport sector supported eight million jobs and contributed $365

Long Islanders were invited Sunday to take a trip down memory lane – in classic cars, motorcycles and airplanes.

The Bayport Aerodrome Society welcomed the public to revel in transportation of times past at the second annual Celebration of Vintage Transportation show, a week ahead of the Island’s beloved Bethpage Air Show at Jones Beach. Collectors and enthusiasts showcased rows of antique and vintage motorcycles and automobiles along the grassy space; behind them, 24 hangars – some intricately decorated – were opened to reveal more than 30 biplanes, Champs and Cubs, many from World War II. To the right of the property, two-seater Pipers took off and landed casually on Long Island’s only grass airfield.

Bayport Aerodrome opened its hangars to the public

The free event, co-hosted by the Bayport Aerodrome Society, the Big Sandbar Chapter of the Antique Motorcycle Club of America and the Vanderbilt Region of the Antique Automobile Club of America, is the only one of its kind in the region. In addition to the display, the event also featured food, music, vendors, a people’s choice competition and raffles – one of which gave guests a chance to win a plane ride that afternoon. The event also accepted donations to go toward charity.

The effortless balance between three modes of transportation did not only signify a unity between enthusiasts, but a sincere interest from the community, as hundreds of Long Islanders flocked

3-D printing has become a powerful tool for engineers and designers, allowing them to do “rapid prototyping” by creating a physical copy of a proposed design.

But what if you decide to make changes? You may have to go back, change the design and print the whole thing again, perhaps more than once. So Cornell researchers have come up with an interactive prototyping system that prints what you are designing as you design it; the designer can pause anywhere in the process to test, measure and, if necessary, make changes that will be added to the physical model still in the printer.

“We are going from human-computer interaction to human-machine interaction,” said graduate student Huaishu Peng, who described the On-the-Fly-Print system in a paper presented at the 2016 ACM Conference for Human Computer Interaction, May 7-12 in San Jose, California. Co-authors are François Guimbretière, associate professor of information science; Steve Marschner, professor of computer science; and doctoral student Rundong Wu.

Their system uses an improved version of an innovative “WirePrint” printer developed in a collaboration between Guimbretière’s lab and the Hasso Platner Institute in Potsdam, Germany.

In conventional 3-D printing, a nozzle scans across a stage depositing drops of plastic, rising slightly after each pass to build an object in a series of layers. With the WirePrint technique the nozzle extrudes a rope of quick-hardening plastic to create a wire frame that represents the surface of the solid object described in a computer-aided design (CAD) file. WirePrint aimed to speed prototyping by creating
