Simple Delta Model Development

Simple Delta SD5 based on MAV model, has not enough power to climb. Moments of inertia were increased to that of the SPORT model, which may make it too sluggish, however, the power parameters need to be adjusted.

from mav.xml

<mass_inertia version="1" units="0" Mass="0.0034254" I_xx="4.21067e-05"

I_yy="4.72453e-05" I_zz="9.1537e-05" I_xz="-1.29652e-06" />

From SD5

<mass_inertia version="1" units="0" Mass="0.0113061" I_xx="0.0456257"

I_yy="0.0445163" I_zz="0.0882453" I_xz="0.00304607" />

Now we come to the power settings

</engine>

</shaft>

</battery>

</automagic>

</power>

We ask ChatGPT to interpret this, and changed th epropeler size from 6 cm to 12 cm. Roll rates are very low due to inertia, and the plane floats and floats, displays strange charactersitics when belly landing

The provided configuration file seems to be describing parameters for a radio-controlled model within a simulator. It appears to specify various aspects of the model's power system, including the motor, battery, shaft, and propeller. Here's an interpretation of the parameters and how you can increase motor power and propeller size:

power:
- This section seems to encompass the entire power system of the model.
power units="1":
- The power section indicates that there is one unit of power. This could mean that there is one motor and one power source.
automagic:
- It seems to be a subsection describing various characteristics of the power system.
F="0.222411" and V="11.076536":
- These parameters within the automagic section may refer to some characteristics of the motor system, possibly relating to thrust (F) and velocity (V).
battery:
- This section seems to define properties related to the battery that powers the model.
throttle_min="0.0":
- This parameter might specify the minimum throttle setting for the model's motor.
automagic T="420":
- This appears to relate to a property of the battery or motor system, possibly thrust (T) or torque.
shaft:
- It defines characteristics of the motor shaft and associated components.
J="0" and brake="0":
- These parameters could be related to the inertia (J) of the shaft and whether a brake system is enabled or not.
propeller:
- This section defines parameters related to the propeller used in the model.
D="0.06096" and H="0.042672":
- These parameters seem to represent the diameter (D) and pitch (H) of the propeller.
n_fold="-1":
- The value of -1 for n_fold might indicate that the propeller is not a folding type, as positive values are often used to specify the number of propeller blades in folding props.
engine:
- This section appears to describe characteristics of the model's engine or motor.
automagic omega_p="2827":
- This parameter might represent the motor's rotational speed (omega_p).
eta_opt="0.78" and eta="0.7":
- These parameters may be related to the motor's efficiency (eta) under optimal and general conditions.

To increase motor power and propeller size, you can consider the following modifications:

Motor Power:
- To increase motor power, you can look into the following options:
  - Choose a motor with a higher omega_p value (higher rotational speed).
  - Increase the thrust (T) value by selecting a more powerful motor.
  - Check if there are other motor-related parameters not listed in this configuration file that can be adjusted for increased power.
Propeller Size:
- To increase propeller size, you can consider the following:
  - Increase the propeller diameter (D) for more thrust, but keep in mind that this may require a more powerful motor to handle the larger propeller.
  - Adjust the pitch (H) of the propeller to match the motor's capabilities and desired performance characteristics.

Remember that modifying these parameters should be done cautiously, as changing one component may require adjustments in other components to maintain balance and efficiency in the model's performance. Always refer to the manufacturer's recommendations and guidelines for your specific radio-controlled model and simulator for safe and effective modifications.

Regenerate

Simple delta planes, sometimes a single sheet of foam board, are interesting for their ability to be built quickly and fly slowly if needed. Could this be a good trainer? I build one for CRRCSIM.

First, some example models:

The last one has a 30 inch, 76 cm span wing. It flies slow enough, so anything with similar wing area should fly the same, with proper stabilizers. It is somewhat of an experiment. The Boeing Microfighter has a span of 5 metres or so, and the Mirage III 8.22 metres, so that leaves some leeway for a 1:10 scale model.

The weight of the model is not known, but the author has listed the components

Motor: BE1806-2300KV Prop: 6x4 Battery: 850mAh 3S Radio: FlySky FS-i6

The motor weighs Weight: 22g

And the build thread: https://www.rcgroups.com/forums/showthread.php?2145562-SIMPLEST-simple-delta-with-simple-plans/page3

All that remains is to build a model to similar dimensions and add some scale details, then edit the configuration file of the SuperZagi.

Choose a suitable scale model..

Preliminary design with a flat delta wing and flat sided foam (recylceable alternative better) and a roll of card for the exhuast

Need to design space for the battery, receiver and ESC and wing cutout

For the 3D model, 3D versions of the RC components are also to be created for planning purposes.

Motor: BE1806-2300KV Dimensions: 23 × 21mm

Prop: 6x4 6 inches = 15cm

Battery: 850mAh 3S

Dimensions: Tattu 850mAh 3S Lipo battery dimensions is: 59*30*24mm/2.32*1.18*0.94inch; Approx Weight:85g/0.19l

Radio: FlySky FS-i6

Receiver:5.1 x 2 x 0.01 inches
