A report on the evolution of jet engines

F-9F-8T Cougars Did we miss any? Did they just hand out an aircraft contract to everybody or what? Is it any wonder that the Navy was "running out of money" by the end of the s after an orgy of aircraft carrier-dedicated aircraft spending?

A report on the evolution of jet engines

The following anecdote suggests Pirie had "help" in the murder of the Navy's seaplanes. Parker aka bobnutes1 aol. Ralph Hendrix kemo chief engine mechanic. The mine bay was capable of carrying 10 each lb mines or being equipped as an air-to-air refueling tanker with drogue chute and tanker hose with bladder tanks.

I was present when Admiral Hyman Rickover came to witness the second flight of ship 4 the first week in August The test pilot in charge was C. Corb Johnson, a huge careful man.

The oxygen regulator was not to his liking and the flight was scrubbed with the admiral sitting in his caddy limo. A few weeks later, the program was cancelled in favor of the nuclear sub and nuclear missile programs headed by Rickover. Ship 9 had just arrived on Strawberry Point. Ships were still under assembly at main plant.

The beaching vehicle was a problem along with the foul weather during the winter months.

The sight of the airplane with the chase plane, a RB over the Strawberry Facility was a joyful sight. Hats off for the men and women who assembled and flew this great aircraft.

Thanks for handicapping our Navy. Jimmy Doolittle versus Glenn Martin: People cause wars and they live on land. To get political effect, warfare must affect people on land. One of the tragedies of WW2 is that we walked away from it learning the wrong lessons in a case of who-gets-the-land-attack-licks-in-first, being remembered and emulated in our current un-balanced and dangerously unready naval force structure.

If a weapon system does not achieve political effects it will not be rewarded by the tax payers with a continued existence regardless of how important or vital the roles it performs at sea where no one sees them doing these heroic deeds nor gives a damn.

When a nation-state is attacked it wants BLOOD not operational art that provides leverage to end a war with the least amount of blood being shed.

Land Attack LA provides the "red meat" the public wants in a "feeding frenzy" of revenge. Before WW2, the Navy had realized it needed long-range, large seaplanes and refuel tender ships to range out ahead of its fleet much farther than any land-based planes could reach and certainly any wheel landing gear small airplanes from a carrier could reach.

At a critical juncture the twin-engined PBY Catalina seaplane was put into mass-production and it gave us the critical edge in both the Atlantic and the Pacific at finding enemy submarines and surface ships first and then enabling naval commanders to "shape" the sea battlefield so we ganged up combined all elements into a stronger whole than the enemy could defeat individually; cargo ship escort aircraft carriers by the dozens with hundreds of short-range planes, long-range LTA blimps and land-based patrol planes, small seaplanes from smaller ships etc.

However, Martin was already thinking of projecting LA power by large seaplanes in two ways; by firepower using them as long-range bombers to smash land targets and for maneuver delivering ground troops to defeat land armies, hold key terrain and eventually topple the enemy nation-state government.

To do firepower LA from a seaplane across oceans, you first need range and enough speed to survive enemy land-based fighter interception. Being able to land on the water in the ocean to refuel from surface or submarine tenders was and still is a HUGE advantage, but the fuselage boat shape is not and hurts aerodynamically with speed reducing drag.

When Martin designed his supersized Mars "Sky Battleship" seaplane with 4 engines to carry enough fuel, he got the range but not the speed to do LA bombing at least during the daylight hours; the plane flies today as a forest fire water bomber at mph. At this critical, pre-Pearl Harbor Japanese attack juncture, the Navy told him to make the Mars a transport and this tragically stopped seaplane LA development for a decade.

And most importantly for getting the necessary political visibility effect to make a place for seaplanes, the Mars bomber was not ready when the Japanese took our bait and attacked our WW1 battleships at Pearl Harbor so the American people would be pissed off enough to declare war on them and by alliance fight the real mortal threat to America, the high technology Nazi Germans.

As our WW1 battleships were being quickly refloated and patched up to go kick the Japanese's asses, plans were underway pardon the pun for Army Air Corp land-based Bs to do a short take-off from a Navy aircraft carrier and strike back immediately at the Japanese to assuage the American public's need for revenge and serve notice to the Japanese that their home islands were not safe and to expect more to come.

In contrast, the Mars seaplane could cruise at mph but could fly for 4, miles unrefueled only risk a couple of tender ships and deliver 34, pounds of bombs!. That's over 11 times the amount of bombs one BC could deliver. In fact, with 16 x Doolittle B raiders launching from the Hornet, a pair of Mars seaplanes could deliver more damage than a squadron and a half Bs at 50 mph slower speed, which if done at NIGHT would be a wash.

As we know now with hindsight, no Bs were shot down even during daylight on the surprise Doolittle raid, but resulted in the execution deaths of some brave Americans by the sore loser asshole Jap militarists after they were forced down in China and captured.

Which in any case was high-tailing it out of the area before they got attacked and sunk. So here is the point, and I'm sure you see it coming.

There is a good chance that NONE of these raiders would have died at all. None would have been forced to crashland or bail out in China because they didn't have a way home.Essay The Evolution of Jet Engines The jet engine is a complex propulsion device which draws in air by means of an intake, compresses it, heats it by means of an internal combustion engine, which when expelled it turns a turbine to produce thrust, resulting in a force sufficient enough to propell the aircraft in the opposite direction (Morgan 67).

The Jet Engine. Sir Frank Whittle’s jet engine transformed travel. The jet engine has allowed millions of people now to do something that was barely thinkable just 70 years ago – crossing the Atlantic at speed.

Whoosh! It took a little more than one hour of test flight to convince us that Phenom EV, short for “Evolution,” finally has shed the original Phenom ’s matronly image. The diagram to the left illustrates the traditional jet engine, a turbojet, where air is sucked in through the compressor, gets combusted, and then exits the engine through the turbine, which also powers the compressor.

Great engine. Runs flawless, easy to start by hand with a chicken stick. I am running mine on a 18x8 right now because it's still breaking in but I plan to try a 18x10 .
