    Beast Horus

    You may know this aircraft from the previous thread, where I designed it starting from 2015. Well, the project has gained traction and we registered a company building the prototype right now. This new thread is for showing the progress and giving you the opportunity for asking questions. You...

    Mass flow and pressure recovery

    Hi! I am simulating the air inlet ducts (scoop type) for my small jet right now which is approximately the same category as the BD-5 or JSX-2. I read the chapter in "Raymer: Aircraft Design - A conceptual approach" where inlet geometry is discussed (also for the specific BD-5). Speed has to be...

    Problem with static margin and neutral point

    Hi! I was already starting building my scale model (fortunately the wings where the design is already frozen), when I noticed I had one small error in my CoG calculation (CoG of fuselage estimated too much in the front, as front half has almost twice the carbon as the rear half). Now I did not...

    "Beast One" - the next generation Microjet

    Hi fellow homebuilders! This is the thread where I am answering all questions about the "Beast One" Microjet that I am building. The "Beast One" is meant as a successor to the infamous BD-5 and as a better alternative to the JSX-2. In years of research I have analyzed all shortcomings and...

    Aerobatic T-Tail

    Hi, as some may know, I am working on a Microjet. The design is using a conventional tail, similar to a BAE Hawk. Now, the problem is that below the elevator you get a lot of interference drag and that also spin behavior is not the best (hence the huge ventral fin). When changing the design...

    Internal aileron linkage

    I am interested in what internal aileron linkage methods you know of. I am only aware of how it is done in the Cirrus SR22, but I don't like the way they are using cables. Is there any good solution to do it push/pull tubes? The easiest solution would be to "shorten" the lever arm in the...

    Canopy frame design

    My project has a 3mm Plexi window over a carbon frame, with the form of the window already fixed, but the rest of the details are still out for discussion. I have watched a video () where a guy is asking Mr Jonkers about their new JS-3 glider. Apart from the stunning details they added to this...

    Beast One - Part #1: Building the mockup

    As space constraints are the biggest problem, the project begins with the build of a mockup. Center of gravity is not allowed to move much and the space available is not much more than for a glider. So most things will have only one possibility where to fit them. The mockup is used as sort of a...

    Split rudder solution and their effect on flutter

    Hi, as the Beast is designed to cruise at 220kt and topspeed should be above 260kt, I am going through great lengths to remove the likelyhood of flutter everywhere possible. The problem we have to face is, that the engine produces around 150N of thrust at idle. The BD-5 is using a thrust...

    Carbon over honeycomb

    Hi! Recently I read a paper about asymmetric composite thickness optimization, where it said you should use a coupling layer as ort of bonding help over honeycomb. They used an additional layer of 80g/m² of glass as it is "loosely woven" and therefore has alot of excess resin. I checked some...

    IFR with certified Garmin G3X

    Hi, a few days ago I saw on Youtube that the G3X can now also be bought in a certified version. I asked whether you could fly IFR by internal GPS on the old uncertified version of the G3X and got the answer, that you would need a GTN650 as you require a certified navigation device. Now, with...

    The "Beast One": What doesn't kill you makes you stronger

    This is the thread where I present the concept of the "Beast One". Unlike the title, it is the goal to create an economic BD-5 alike single seat jet which on the contrary to the BD-5 won't try to actually kill you. The plane is not about re-inventing the wheel, nor to follow this stupid higher...

    Integrated aerobatic fuel tank with exotic engine

    Hi, for my project I would like to build integrated wing tanks located between double spars (like Cirrus and Diamond but without the aluminum). The wing is is built from carbon over honeycomb and it will use Jet A1. Short durations of inverted flight should be possible (5min). I have knowledge...

    FADEC with Garmin G3X Touch

    Hi, for our project we would like to use a powerplant which sends the engine parameters via FADEC. All sensors are buried inside and are not really accessible. The Garmin G3X Touch has a FADEC interface, but according to the manual you can only select Rotax and UL-Power. Is there a way to use...
