Conversation with an aircraft propeller designer, the ongoing search for MH370, LaGuardia Airport: Delta skids off the runway and the “perimeter rule” may become history, and NASA has plans for NP2000 propellers,
Anthony Falzone is the developer of the open source, public domain aircraft propeller design software named PROP_DESIGN.
We talk with Anthony about basic propeller design parameters and the mathematics involved. He tells us why propellers (which are really rotating wings) have different numbers of blades, and he explains propeller pitch, including variable pitch props.
PROP_DESIGN can be used to design aircraft propellers, but it also works for similar products such as propfans, open rotors, unducted fans, and geared turbofans. With the software, you can find the optimum geometry for any given operating condition, analyze takeoff condition, design swept blades, and much more.
Anthony is retired now, but he worked in the aerospace industry for over twelve years, holding positions at Hamilton Standard, Pratt & Whitney, McCauley Propeller Systems, and Atlantic Inertial Systems. He also did contract work for the Air Force Compressor Aero Research Lab, and designed the propeller for the General Atomics Predator B and Altair unmanned aerial vehicles.
On the March 8 anniversary of the disappearance of flight MH370, the Malaysian Ministry of Transport made available the MH370 Safety Investigation website, which provides links to the Interim Statement and Factual Information on the investigation of Malaysia Airlines Flight MH370.
Australian Deputy Prime Minister Warren Truss has said the country’s search for missing Malaysia Airlines flight MH370 “cannot go on forever.” The current phase of the search is scheduled to end in May.
The Delta Air Lines Inc. plane that skidded off a runway at LaGuardia Airport last week injured 23 passengers and damaged about 940 feet of the airport’s perimeter fence.
You can fly from New York’s JFK airport to California, and you can fly from Newark Liberty airport to California, but under the “perimeter rule,” in most cases you can’t fly from LaGuardia to a destination more than 1,500 miles away. Except on Saturday or to Denver.
The perimeter rule was established in 1984 to combat overcrowding at LaGuardia, but the Port Authority of New York and New Jersey is considering lifting the rule.
NASA selects UTC Aerospace Systems NP2000 Propellers and Electronic Propeller Control Systems for a P-3 aircraft
The NP 2000 propellers are large, 8-bladed propellers used on the Northrop Grumman E-2C Hawkeye (a tactical airborne early warning aircraft), the Grumman C-2A Greyhound (twin turboprop cargo plane used for aircraft carriers), and on C-130 Air National Guard aircraft.
NASA uses their P-3 for scientific investigations and as a technology test bed for new airborne and satellite instrumentation.
