All of that extra wetted area read drag and weight requires a bigger rubber band to make it fly, and that it has. The older version could stay aloft for 40 hours powered by the ubiquitous Rotax , a hp turbocharged version of the Rotax seen in most LSAs. Despite this gargantuan jump in power, it can fly missions of more than 30 hours duration. On static display last year, the Icon A-5 amphibian was demonstrated at the air show site and the EAA seaplane base on nearby Lake Winnebago.

With sleek aerodynamics lines, automobile-like landing and taxi lights and an instrument panel more like that in a Lamborghini supercar, it makes a big first impression. Although no specific materials for the production version have been called out, the folks at Icon Aircraft Los Angeles, Calif. In the case of the prototype on view, some wet layups were used, but this will no doubt be minimized during development, with prepregs predominating.

The wing is fairly conventional, with a top skin molded in one piece, and the spars, ribs and control linkage are installed, with the structural components secondarily bonded.

The bottom skin is molded separately, and bonded onto the underlying structure. The wings are hinged and fold back along the fuselage just outboard of the center section the exact break may change in the production model.

The main spar is staggered to permit folding the wing. The outer spars are joined to the center section spar for flight with two large pins per wing.

Punta Gorda, Fla. Unlike the Icon , it can seat up to 12 passengers and a crew of two, although a more realistic six-to-eight passenger arrangement is more likely in actual service. Not a really good ratio, but seaplanes are a compromise to begin with, and efficiency is not generally their strong suit. Even though streamline tubing is strong stuff, the structure has to support not only the weight of the powerplants but withstand the combined thrust of the engines as well.

The aircraft and its builder have an interesting history: Prof. After the war, the company became Dornier GmbH and expanded with projects as diverse as a turboprop regional airliner and an open-air, single-seat helicopter, with Prof.

Claudius Dornier, Jr. In , the professor retired as chairman of what was, by then, a very large multinational conglomerate, and returned to seaplane design, launching the an all-composite amphibian, the Seastar , a modernized read compositized version of the Wal German for whale , a similarly sized flying boat from the early s.

In the ensuing litigation, the bulk of the company fell to Fairchild, but Dornier Jr. Nowadays, Conrado Dornier, grandson of the founder, is at the helm. The plane will be built and marketed in the U. Most of the components were made with wet layup — no vacuum bags, no bladders.

It's great to thank veterans for their service, but perhaps better to understand what we ask them to do in the first place.

And why. Read more. Featured Video. Paul Bertorelli - November 7, Yearly favorites such as Sean D. Look for even more top performers to be added to the list in early The afternoon air show is an anticipated spectacle each day at EAA AirVenture, providing an exciting way to round out to a full day on the Oshkosh flight line.

In , the best elements of the daily air show and the "showcase" flying from previous years will be combined to provide several hours of exciting and entertaining aerial entertainment. I have a lot of respect for Alan in that regard. Who knows whether that will work out? It was clearly their choice. Piper is hiring 50 new engineers for the PiperJet program.

At the same time, slow sales of existing products forced the company to lay off about 60 production workers. According to Kromer, Piper booked a significant number of orders for the new Archer at a pre-AirVenture dealer meeting. Time to climb to the 35,foot maximum altitude will be 18 minutes or 22 minutes at a higher cruise-climb speed. PiperJet orders currently stand at aircraft for retail customers and more for Piper dealers.

There was some concern that the placement of the engine on the vertical stabilizer would cause pitch changes with power application, but that problem has been solved, Kromer said. A passive variable thrust-vectored nozzle designed by Williams engineers automatically deflects thrust to counteract pitching moments.

The nozzle employs the Coanda effect, using no moving parts and adjusting the vector of the thrust depending on the strength of the air flowing through the nozzle. Imprimis is committed to long-term strategic investment in Piper, according to Kromer. We have the appetite for that process. Stratos is based in Bend, Ore. Those companies trained a lot of people on composite design and manufacturing, including Stratos chief technology officer and vice president of engineering Carsten Sundin, who worked for kit manufacturers Lancair and Epic Aircraft.

The goal of knots and 1, nm range is easily achievable in a twinjet, but all jets that offer that level of performance also have more seating capacity in addition to the greater initial and ongoing costs. Why pay for eight seats, Lemaire wondered, when all he wanted was a roomy four?

What Lemaire and the Stratos team discovered was a sweet spot in the market niche lineup for something like the , with high performance, low cost and plenty of room to enjoy the flight. The performance goals assume four pound occupants, each with a pound bag and one pound flight bag for the pilot. A challenge for single-engine jet designers is the location of the engine.

But these configurations run the risk of pitch changes when power is changed and require additional design work to minimize or eliminate this effect. One optimal solution, chosen by both Stratos and Diamond on its D-Jet, is to embed the engine in the fuselage and channel airflow through inlets grafted to the fuselage.

Turbine engines are finicky and demand a clean and uniform flow of air, so the design of the ducts that deliver the air to the engine is critical. The mid-fuselage engine installation has an added benefit for the Stratos And that location also helps provide a wide cg range so that owners will find that no matter what they carry, the CG will remain within that range unless they opt to transport lead bricks.
