PT6 Celebrates Fifty Years Part 1

When it was developed in 1963, the PT6 was the first turboprop engine rated at 450 shaft horsepower, impressing Beechcraft to the point that the company chose to install the engine in their King Air line of turboprop twins.  Fast-forward 50 years, and Beechcraft still choose the PT6, although of ever-increasing power ratings, to power their engines.

 Before The PT6

beechcraftPratt & Whitney began development of the PT6 in the late 1950’s in an attempt to replace the manufacturer’s Wasp radial engines, developed during in the 1930’s.  In 1925, Frederick Rentschler, President of Wright Aeronautical, approached his brother, Gordon, and Edward Deeds, who were both on the board of Niles Bement Pond, convincing them that Pratt & Whitney Machine Tool, a subsidiary of Niles, should fund the creation of a new aircraft engine Rentschler and a colleage, George Mead, were developing.  The engine was to be a large, air-cooled radial design.  The executives at Pratt & Whitney saw an opportunity for growth and lent Rentschler $250,000, the use of the Pratt & Whitney name and space in their building to begin creating the new engine.  Rentschler left Wright Aeronautical and took over operations of Pratt & Whitney Aircraft Division, The first of the Wasp series debuted on December 24, 1925, quickly becoming one of the most widely used aircraft engines in the industry due to their superior speed, rate of climb and reliability.  Charles Lindbergh and Ameila Earhart both set records in Wasp-powered aircraft.

Wasp to Hornet

 With the development of the PT6 still a few decades away, Pratt & Whitney created the next line of radial engines, the Hornet, rated at 525 horsepower.  The dependability of both the Wasp and the Hornet made them very popular among commercial aircraft, and as the public use of air travel increased, so did the demand for Pratt & Whitney engines.  As it became apparent that the United States would enter World War II, President Franklin D. Roosevelt called on manufacturers to produce 50,000 aircraft a year for military use, requiring Pratt & Whitney to expand its workforce from 3,000 to 40,000.  Throughout the war, Pratt & Whitney continued to innovate, until, by the end of the war, their largest engine provided 3,600 horsepower.  However, radial engines were slowly being replaced by lighter turboprop engines.

Vision of the PT6

In 1957, Pratt & Whitney saw an opportunity to channel profits from the piston engine spare parts business to the development of smaller gas turbine engines than those currently being manufactured in the United States. The company gathered a team of 12 young engineers after conducting market studies that found there was a need for a 500 shaft horsepower engine that could replace piston engines, such as the Wasp and Hornet.  In December 1963, Pratt & Whitney shipped the first of the PT6 series, the PT6A-6, a highly innovative gas turbine representing technology advances that were significant at the time.  Because gas turbines have a higher power to weight ratio than piston engines, the PT6 was perfect for aviation engines.

pt6aThe PT6 has enjoyed a rich and colorful history since it began production in 1963, and Pratt & Whitney is proud to celebrate the 50th anniversary of this timeless aircraft engine.  Learn more about the colorful past, pioneers who flew this engine and continuing evolution of an engine ahead of its time.  For more information on the PT6 or about aircraft maintenance, contact Covington Aircraft online or by telephone today.

Aviation Station: Landing Equipment/Landing Gear

landing gear

Pilots use cockpit controls that receive information from the engine, like the PT-6A, for optimum ground handling of turbo prop airplanes. However, without landing equipment and gear, the plane could not be controlled on the ground at all.  Landing equipment and gear are used for takeoff, landing, and taxiing of an airplane.

Conventional Landing Gear

Planes with two wheels forward of the aircraft’s center of gravity are known as conventional landing gear.  Often seen in older aircraft, pilots must brake carefully as, without a wheel at the front of the plane, the turbo prop airplanes pitch easily.  Because the tail is free to move in any direction, planes with conventional landing gear are difficult to control when landing or taking off, even with the cockpit controls found with the PT-6A engine.

Tricycle Landing Gear

Tricycle landing gear looks much like its name indicates, with one wheel on the nose of the plane and two main wheels.  This configuration makes the plane less likely to tip over and easier to handle on the ground.

Tandem Landing Gear

Used for very large aircraft, tandem landing gear has two sets of main landing gear, located one behind the other on the fuselage.  This allows planes with highly flexible wings to be better managed on the ground.  In some cases, small wheels are added to the tips of the wings to keep them from scraping the ground.

Cockpit Controls

Turbo prop airplanes, such as the PT-6A, often have cockpit power-plant controls for greater ground-handling capability.  Although these controls focus on propeller control, the propeller and landing gear often work in tandem, especially during takeoff and landing.   Because landing equipment and gear are a crucial part of the ground operations of any airplane, these cockpit controls found on the PT-6A play an important role in ensuring the safe takeoff and landing of turboprop airplanes.

Corporate Jet Series – Most Expensive Celebrity Business Jets blog – Covington Aircraft

Which Celebrity Owns the Most Expensive Business Jet?

Information about the highest-priced jets owned by celebrities  is not easy to find.

The answer to this question will have to be a multiple answer because the price paid for a business jet can add up to a good deal more than the price of the jet. With the price of customization of an aircraft as an unknown, it is hard to determine which high-flying palace cost the most.  The concession will be a listing of who owns what and let your imagination run wild from there. One thing is for certain, there are people out there who own some beautiful aircraft.

If we are going to list the most expensive business jets, why not start with the biggest?

The biggest of the business jets we found belongs to Sergey Brin and Larry Page, the co-founders of Google.  Their Boeing 767-200 wide body is by far the biggest. During the customization of the interior, there was a legal issue with the designer, so the total cost of refurbishment included legal fees.  This flying penthouse features two private staterooms, seating for fifty and, of course, a kitchen.

John Travolta loves to fly his Boeing 707-138B.

QANTAS-John-Travolta-707-100B-N707JT-59-V-JetGrd-MIA-BDLRThe price of this plane comes into question. John received his 707B from Quantas Airlines as payment for his continued ambassadorship for the airline. Built in 1964, the 138B was a model only purchased by Quantas. This model is 10 feet shorter in the rear fuselage, making it the shortest of the 707’s and helping to give it an increased range. Purchased by Quantas new, it has since been through a number of owners, including Frank Sinatra from 1972 to 1975.  It shares its home with a vintage Gulfstream IISP and the Travolta family. Yes, the family lives in a home near Ocala, Fla., off of John’s 1.4 mile private airstrip.  The planes are both berthed in carport-like structures that are attached to the home.  The Travolta home resembles a squat control tower. The 707 is the family vehicle while the Gulfstream is John’s sports car.

Oprah cruises around at Mach 0.85.

Oprah-JetThe leathery interior of the Bombardier Global Express XSR was purchased by the production company, HARPO, for Oprah Winfrey.  It’s touted as the most expensive business jet at $49.3 million just for the jet, excluding interior furnishings.  With a 94-foot wingspan and a 99-foot, 5-inch length, it is not as large as the commercial liners, but it will leave them behind.  Cruising at Mach 0.85 (Mach 0.89 top speed) it will travel 6,150 miles with a ceiling of 51,000 feet.  Designed to seat nine and a crew of four, the cabin sports 6 foot, 3 inches of head room and a floor-line width of 6 foot, 11 inches with a length of 48 feet. This aircraft has been in production since 2005.
