BO-105 PAH1A1 progress news

[Flagrum]

Uh - thanks, Flagrum...I was typing too fast ;).

 

"Can you tell us what type of NAV system that is? So we can start googling for infos and manuals ... :o)"

 

Do you mean. The Doppler ?

Yes, "DPLR NAV". Sooo many buttons ... sweet! :o)

What is it exactly? Or perhaps you even have some links to related information, manuals, etc.?

Textures are looking great! Great Work!

The doppler navigation system AN/ASN-128 is a complete autark navigation

system. It does not need any ground station. position and ground speed is

calculated by the comparing two radar reflection frequency generated by

several on board directional antennas. Since one pair of antennas are

directed forward and a second pair backwards, the received reflections

differ slightly in frequency, because the helicopter moves towards the

forward reflection point and away from the backward reflection point. The

effect is comparable with the situation of a train passing by. If the train

moves towards the listener, he hears the sound on a higher frequency. If it

is passed by, the sound is on a lower frequency. The frequency delta is the

base for speed and direction calculations. Based on the initial home

location, the current position can be calculated by continuous incremented

speed vectors. In former times, the precision was very poor. It needed

periodic manual corrections by the operator. The state of the art doppler

systems are very precise because the newer hardware works on higher clock

cycles and is more sensitive. Even the use of laser gyros enhanced the

system precision. There are still some restrictions to be maintained to

avoid signal misinterpretation. These are turns with more than 45° bank or

pitch higher than 30°.

 

It displays:

 

- your present Position to your destination in longitude and latitude and/or transversal mercator coordinates

 

- Groundspeed in km/h or knots

 

- Steercourse over ground in degrees

 

- Sphäroidcode to Destination (Entered via Keyboard)

 

- flightpath deviation to Destinaton (Entered via Keyboard)......

Thanx, Cobra :)

[Devrim]

Fragger, I'm excited for this machine.

Thank you so much for making this.

 

Best wishes.

Great progress! :thumbup:

Looks amazing, I have been following you work for a while know and I can't wait to get my hands on it. I was wondering, are you going to go with just the AN/ASN-128? or upgrade to the AN/ASN-128B or D? We have been using the AN/ASN-128B/D's in the uh-60A/L's for a long time. It integrates both Doppler and Gps. We dont use the Doppler part anymore, its pain in the ass to keep updating with known points to keep it accurate and on course and its not near is accurate as Gps. Not sure what the real Bo-105 used but I cant imagine only having Doppler after all these years.

 

Keep of the great work.

I just want to bring the helicopter to a "default state" Once the whole helicopter is finished, I will upgrade the devices to a more modern state. That state will feature the SEM-91 (VHF/FM), XT-3010/01 (UHF/AM) and a more modern version of the Doppler. Basically I would like to have a menu where you can choose your configuration.

 

And, by the way, I'm not a friend of modern devices. That's because of the more technology a device/plane/helicopter have, the more the possibillity increases of failing (in real life):smilewink:

 

Best example is the Tiger/Eurofighter/NH90 :D

Centerpanel update.

 

Centerpanel is finished and features the UHF-Panel.

On a closer look I recognize that I missed modeling the Ventilation panel. Besides, the floortexture have to be adjusted :doh:. Shame on me.

thanks for sharing, looking great as usual

[Darkwolf]

LOVE IT !

[REL]

WOW!!!

[Andi31]

Wow great updates.. I wish you success for your Bo, that it gets the best DCS module ;) I can't wait :thumbup:

 

Also I wish everyone merry Christmas and a happy new year :)

Do I spot another "RETARN"? :D

[GeorgeLKMT]

Really great work!

 

But what caught my eye was use of word "megacycles". Ha, ever heard of that one. Only more ridiculous I can think of is "million of back-and-forths" :D

[VTJS17_Fire]

Thanks for the update and I wish you merry X-Mas.

 

 

Fire

Uh -forgot to correct it on the second box :music_whistling:

A specific frequency is expressed in Hertz. Means, the number of full electro magnetic wave cycles per second. If you speak about (Example) a VHF frequency of 122.1 MHz, then you can even say 122 100 000 Hz or 122 100 000 Cycles, which is 122.1 Mega Cycles.

[GeorgeLKMT]

As a electrician myself, I know this stuff. It's just that I really never heard of using the word "megacycles" before. ;)

that's the german way and It's comparable with a german phrase which says: "bureacracy is making simple definitions difficult"

Will Chuck Aaron's Red Bull paint scheme be included in the module? :lol:

And the composite rotor blades mounted to a solid titanium fixed rotor head. :P

This one will be included as well but I first want to bring out the Anti-Tank version.

Wow you are talented!
