A hypothetical German experimental aircraft from WWII.

Essentially a gyrocopter, the blades were variable pitch. For take off, the Strahlrohr baffles in the rear jet wash box behind the BMW engine would be raised, directing the exhaust onto the rotor to spin it up allowing vertical take off. Once the rotor was spinning, the baffles would be orientated horizontally and the jet engine then provided the forward thrust as normal.

A new Flying Site for Phoenix Flight Sim. Star Wars!

As the mighty Imperial Battle Fleet jumps in from hyperspace to reinforce the partially complete yet functional Death Star, Han Solo in the Millennium Falcon, pursued by the evil Darth Vader rushes to join the fight. Nothing will stop him, not even Vader.

Anticipating the impending attack, the Rebel space fleet barely manages to escape in time evacuating the innocent, women and children who have fled their homes.

The Imperial Death Star fires its main superlaser weapon blasting the Rebel Planet apart which explodes in a massive fireball spewing molten debris into space as it is ripped asunder. The Death Star launches its TIE fighter squadrons to counter the oncoming Rebel Xwing forces who are lead by Luke Skywalker himself. May the Force be with him.

Let battle commence!

Can you find Darth Vader?

A new flight video for Leonardo da Vinci's Air Screw for Phoenix Sim.

Leonardo Air Screw for Phoenix Flight Simulator (1 min 15 sec)


Leonardo is credited with inventing the helicopter with his Air Screw. In fairness he was probably influenced by the Chinese Top.

The idea was a bunch of guys would stand on the platform and running round the mast, turn the capstan thus providing power to the screw so generating lift.

The original Sketchup model was created by alfebilbao and took quite a lot of modification to get it into Phoenix Builder.

The Phoenix model can be downloaded here.

Piasecki H 21 Banana (2 min 16 sec)


You can download the model here


The Piasecki H-21 Workhorse/Shawnee is an American helicopter, the fourth of a line of tandem rotor helicopters designed and built by Piasecki Helicopter (later Boeing Vertol). It was a multi-mission helicopter and first flew in 1952.

The H-21 was nicknamed the "flying banana" because of the upward angle of the aft fuselage which ensured that the large rotors could not strike the fuselage in any flight attitude.

The H-21 uses two tandem, three-bladed counter-rotating rotors, and was powered by a nine-cylinder Curtis-Wright R-1820-103 Cyclone 1,150 hp air-cooled radial engine.

In 1959 Piasecki Helicopters came up with a concept for heavy lift over short distances where between two and six H-21Bs would be linked by beams to lift heavy loads. It was considered to be unsafe and never implemented. Presumably that is what the channel in the aft of the fuselage was intended for.

RickP made a beautiful Blender model and gave me the pleasure of getting it flying in Phoenix.

Vought Sikorsky VS-300 Experimental Prototype Helicopter (1939) (1 min 2 sec)


You can download the model here

Igor Ivanovich Sikorsky, the Father of Modern Helicopters was born in Kiev, Russia in 1889.

In 1931 he filed a Patent for a direct lift aircraft which was awarded in 1935 and as the Engineering Manager of the Vought-Sikorsky Division of UAC in 1938 he started to develop his dream, the VS-300 experimental helicopter. The first untethered flight was demonstrated in 1940 as shown in the video.

The VS-300 was fitted with a Lycoming O-145-C, horizontally opposed four cylinder, 75 hp air cooled engine. It had a three-blade main rotor and a vertical antitorque tail rotor. The tail rotors (at one stage three) were driven by a shaft along the tail boom and a complex system of gears, belts and pulleys.

This configuration of a single main rotor with collective and cyclic control and a shaft driven vertical tail rotor is found today in most modern helicopters.

The helicopter underwent a series of modifications. Initially cyclic control of pitch and roll was ineffective so at one stage, side gantries were added at the end of the tail boom to support two lateral, horizontally orientated variable pitch rotors. By varying pitch of these rotors simultaneously, fore and aft control was provided. Roll was provided by differential pitching of the blades. Sikorsky found that in this configuration the VS-300 could not fly forward easily and he joked about...Continue Reading

Pitts Sky Car "Umbrella" Ornithopter (2 min 8 sec)



We have all seen the movies of this early ornithopter pumping and bouncing as seen in the 2nd video below and had a good laugh. However, the idea was not quite as ridiculous as it may seem at first sight.

The "umbrella" was not just a simple membrane which of course would be unable to provide any lift. It was in fact an ingenious and sophisticated device that had been well thought out even if it wasn't successful.

It was composed of sixty radial slats that opened on the upstroke allowing air to pass through and closed on the downstroke trapping and forcing air down. In addition, it also spun on each stroke in an attempt to generate more lift. These movements were driven by a complex mechanism with gears and cranks to generate the spin and reciprocation. 

"Jack" John W. Pitts filed a Patent for his idea in 1924 which was granted in 1926. Pitts, in collaboration with W. P. Kindree constructed two versions, the first of which was tested in 1928. 

Apart from the Patent and newsreel movies that were made, little more is known about Pitts or his aircraft. 

The first version which is modeled here was powered by a 65 hp engine of unknown manufacture. The second version was much more robust but weighed a massive 1,200 Kg (!) and was powered by a Curtis OX-5 90 hp engine.

As It was not possible to determine the manufacture of the engine used in the first version, the Curtis ...Continue Reading

Flying Teapot is the third studio album by the progressive rock band Gong, originally released by Virgin Records in May 1973.It was re-issued later in the year with different cover art by BYG Actuel in France and Japan.

That cover art was used as the texture for the model.


A challenge set by my buddy John although he meant a real model!

Asboth AH Helicopter (1 min 6 sec)


Following the work of Petróczy, Karman and Žurovec (PKZ) around the time of WWI, Hungarian engineer Oszkár von Asboth who had worked on both of the PKZ helicopters and who was a specialist in propeller design and manufacture started to develop the concept and designed and flew four different helicopter between 1928 and 1931.

As with the PKZ series, two counter rotating coaxial rotors were employed which were capable of providing sufficient lift. However, just like the PKZ aircraft, his were also inherently unstable and need to be tethered. Over 250 flights were made, some of which lasted for up to an hour. The helicopters were capable of climbing to an altitude of 30m. The problem of providing forward thrust was addressed with the addition of a forward facing propeller in later versions as with typical fixed wing aircraft.

Looking closely at the few photographs that are available, the two central, lateral panels appear to be articulated with control horns and wires attached. This may have been an attempt to deflect the main rotor down wash to one side or the other to provide some degree of control although it seems to have been ineffective. The front and rear panels were also probably similarly hinged although that is not apparent in the available pictures.

The problems of providing directional control and forward thrust were not solved until the genius Igor Sikorsky invented both collective and cyclic pitch mechanisms...Continue Reading

Lego 42092 Rescue Helicopter with upgraded Blade 130s mechanism.

Upgrades include Rakon Heli Carbon Fibre frame, 180 Trio Three-Blade Head, alloy tail boom, alloy tail motor mount and alloy tail blade fittings.

A breezy day so altitude holding was a little problematic at times hence the bumpy landing.

Not much in the way of modifications need to fit the 130s inside. I cut a carbon fibre plate and after drilling holes to bolt the plate to the Lego kit I then found I could attach the 130s Rakon frame to it! Doh!

So in the end I went with hot glue. It holds well so far and if needed I can free it up with a little isopropyl.

Petróczy, Karman and Žurovec (PKZ)

In 1916, István Petróczy proposed an electrically driven rotorcraft to replace the dangerously flammable observation balloon. His original concept was for the onboard electric motor to be supplied by a dynamo driven by an internal combustion engine.

PKZ-2 WWWI helicopter for Phoenix Flight Sim. (0 min 59 sec)

PKZ-1

The PKZ-1 was designed by Karman and Žurovec. It had four radiating arms with four-bladed propeller on top of each, geared in pairs such that each pair spun in the opposite direction just like a modern Quadcopter.

The rotors were driven from a single centrally located electric motor. A ground-based generator fed power through the tethering cables to the motor. In a short series of four test flights in March 1918 the craft was able to lift three men. The wiring insulation in the motor burned out on the fourth flight and was not repaired.

PKZ-2

The PKZ-2 was developed by Žurovec in parallel with the PKZ-1, but wholly independently. Zurovec only acknowledged the support of Petróczy.

It had three radiating arms, each housing a rotary piston engine. These engines were coupled together to drive a central pair of contra-rotating wooden propellers mounted above the airframe. A round cockpit for the aircrew was fixed centrally, on top of the rotor mast. Landing gear consisted of rubber-fabric cushions, one large central one and three smaller ones at the end of each arm.

The Sikorsky S-58 is a piston engine helicopter developed from the earlier S-55 as an anti-submarine warfare and general utility and transport vehicle for the US Navy. It first flew in March 1954.

It was given the military designation by the US Navy as HSS-1 Seabat in the ASW configuration, HUS-1 Seahorse in the utility configuration and H-34 Choctaw when later adopted by the US Army.

In 1956 one was sent to the UK to serve as a pattern where it was developed further by Westland Helicopters as the Westland Wessex for the British Royal Navy Fleet Air Arm and later the Royal Airforce. It was fitted with a Napier Gazelle turboshaft engine overcoming the piston engine limitations and also with an automatic pilot system and used for ASW, Utility and SAR roles. Sikorsky subsequently developed a turbine version themselves, the S-58T.

Monday 19th April 2021 flight history was made! The first aircaft to fly off world!

Ingenuity coaxial helicopter succeded with its maiden flight after days of delay while new flight software was tested and uploaded.

Here to celebrate is Perseverance at Jesero Crater, Mars flying site for PhoenixRC Simulator.

Made from the 360 deg panorama taken by Perceverance on 20th February 2012 while it waited for Ingenuity to fulfill her destiny.

Edit:

While visiting the Jesero Crater in my Occulus Quest Virtual Reality Headset (an amazing experience!) I realised that the flying site has considerable distortion with a goldfish bowl effect causing the horizon to be too high.

I have consequently rebuilt the site to make it more realistic.

I strongly suggest you download and use Jesero Crater Mars v2 instead, a more realistic rendering.
