Preparing the experiment…
BUILD IT. RUN IT. REPRODUCE IT.
From Lemonergy blocks to the simulation.
Assemble the same model in five stages. Each stage adds real Lemonergy blocks and their wires. Run the completed graph to drive the 3D simulation and plots, or download the exact recipe and rebuild it yourself.
This free builder includes every required block. For manual editing in Simulation Studio, use catalog 2026.10.1 with the Vehicle and Math blocks; an older Studio catalog cannot run this model. Reopen accepts this lab’s model files and computes fresh results.

Exact blocks, parameters and input-port wiring for this stage
Use the palette block shown, set its ID and output quantity, then enter every listed parameter. Connect the source block’s output to the destination row’s input port: in0 is the first input. Feedback wires may connect to a later stage.
| Block ID / name | Palette block | Output quantity | Exact parameters | Wire into each port |

Solver settings and signals to plot
Use these exact solver values. Add Display or Scope to the following block outputs. All quantities are SI; SOC is a fraction and the page displays it as a percentage. Roll angle and angular acceleration use the catalog’s Number quantity, interpreted as rad and rad/s².

ENGINEERING NOTES
Explore an idea.
Keep the assumptions visible.
This is an independent Lemonergy engineering study of suction, gas propulsion and battery demand. The shared reference informed the request for visible physics. The controls, block model and simulated trajectories are authored for Lemonergy. The second-generation exterior uses Tesla Roadster 2020 by metarex.4d, under CC BY 4.0, with adapted materials, lighting and placement. The cutaway hardware is schematic and does not depict Tesla’s production engineering.

Surface adhesion: a static floor, wall or ceiling check, with a 10 s battery run. The required reaction is N = Fₛ + mg cos θ and the grip reserve is μ max(0, N) − |mg sin θ|. A failed check shows an unsupported pose, not a prediction that the car remains attached.
Vertical lift: thrust and gravity determine height; the mass decreases as air leaves. The run is displayed through the first sampled return to the ground plane. It does not predict body impact, suspension travel or a safe landing.
Airborne roll: the lift burn ends before two balanced roll-jet pulses. Each couple has zero net translational force; τ / I drives angular speed and angle. Both opposed jets consume air at 2|τ| / (d vₑ). Constant roll inertia and unchanged tank pressure are assumptions. This is one-axis rotation, not a six-degree-of-freedom vehicle model.
Tank refill: the compressor draws power until the tank is full or the chosen time expires. The stated isothermal estimate is w = R T ln(p₂/p₁) / η. Flow equals P / w; this is a study operating point, not a compressor map.
Battery, component data and validity
The cell choices and pack mass come from Lemonergy’s pinned Designer / Garage parts snapshot. Each cell retains its source basis and estimated fields. Candidate S/P layout is editable and is not a claimed Roadster configuration.
The pack uses constant nominal open-circuit voltage U and series resistance R. I = 2P / [U + √(U² − 4RP)], V = U − IR, heat = I²R, and dSOC/dt = −I/(3600 Q). Negative U² − 4RP flags infeasible electrical demand. Cell continuous current, contactor/fuse carry current and the 5% study SOC floor are checked; pulse capability is not assumed.
Fan pressure and power scale with command squared and cubed. The seal is ideal and fixed hardware does not become stronger when a heavier pack is selected. No OCV–SOC curve, temperature dependence, RC polarization, pressure blow-down, leakage, cooling system, aging, BMS or structural limit is solved. Beyond a rating flag, the trace describes hypothetical demand.
Public nominal ratings do not independently validate these vehicle scenarios. Thrust, inertia, fan operating point, timing, body/rig mass and compressor inputs are editable authored assumptions.
Reproduce the run and trace the sources
Use the guided block builder above, then run the assembled graph. Download the block-by-block recipe for every parameter, wire, solver setting and reference result. Reopen the native model in this lab to rerun it, or import it into Simulation Studio with catalog 2026.10.1 and the required blocks. The model includes its input assumptions, component provenance and engine hash. CSV contains the displayed native samples; the run record includes the graph, solver identity and validity flags.
