SkyEye UAV Catapult Launcher is a high‑efficiency ground launch system designed for fixed‑wing UAVs in the 30‑50kg class. It uses high‑toughness rubber bands for energy storage and a pull‑cord release, delivering a pure mechanical launch speed of 9‑15m/s (not including the UAV’s own propulsion) with an adjustable launch angle of 6°‑8°. This allows UAVs to take off safely without runways or in confined spaces. The whole frame is built from high‑strength aluminium alloy; deployed length is 6.2m with a 5.5m rail, while folded size is only 2.2m, making it easy to transport by vehicle and quick to reposition in the field. Electric winch reset, with a team of 3 people, allows deployment/retrieval in about 10 minutes, greatly improving mission responsiveness. The system operates in temperatures from ‑20°C to 60°C, has an IP54 rating, withstands winds of at least Force 6, and adapts to hard, soft, or sloped terrain – whether in high altitudes, islands, jungles, or disaster zones. It is widely applicable to emergency rescue, border/coastal patrol, power/pipeline inspection, agricultural surveying, environmental monitoring, and more. It is the reliable partner that frees fixed‑wing UAVs from runway dependence and enables mobile deployment.

Frequently Asked Questions

Q1: My UAV weighs exactly 50kg – can the launcher safely launch it?

Yes. The recommended launch weight range is 30‑50kg, so it is well within the limits. However, please ensure the UAV mounting points are compatible with the cradle; if you use a non‑standard model, contact us for a customised cradle in advance.

Q2: Does the launch speed of 9‑15m/s include the UAV’s own motor/engine thrust?

No. This speed is purely the mechanical speed provided by the launcher rail; the UAV’s own thrust adds to it after leaving the rail, resulting in a higher actual take‑off speed. Please set the appropriate release timing according to your flight control logic.

Q3: What if the battery runs out in the field? Is the battery mandatory for reset?

Reset is done by an electric winch that requires an external 12V 80AH lead‑acid battery (user‑supplied). If the battery is dead, manual reset is not possible on site, so we recommend carrying a spare battery or charger. The release operation itself is a mechanical pull‑cord and does not rely on electricity.

Q4: Can it be used on soft ground (grass, sand) or slight slopes? How to ensure launch direction stability?

Yes, the launcher is designed for soft and sloped terrain. However, make sure the rail is firmly set and does not shift due to gravity or recoil. We recommend using ground stakes or ballast, and compensating for the slope with the adjustable launch angle (6°‑8°).

Q5: Does the 10‑minute deployment/retrieval (3 operators) include cradle modification and UAV mounting?

No. The 10 minutes refer only to the time needed to unfold the launcher from its folded state to launch‑ready (or vice versa). It does not include UAV loading, cradle adjustments, or pre‑flight checks. Please allocate extra time for model‑specific adaptation.

Q6: What is the service life of the rubber bands? How to inspect them?

Rubber bands are consumables; their life depends on usage frequency, temperature, and stretch level. Generally, we recommend replacing them every 200‑300 launches or every 12 months (whichever comes first). Check regularly for cracks, hardening, or significant loss of elasticity – if any abnormality is found, stop using and replace immediately.

Q7: What if the UAV gets stuck on the rail or the release hook doesn't disengage during launch?

First, cut off winch power immediately and keep all personnel away from the launch direction. Check whether the slider is fully in place and whether the cradle hook is jammed. For minor mechanical jams, you can use a pry bar or push rod to help release it. If the problem cannot be solved, contact our technical support – do not force launch or use violent disassembly.

Q8: Can it work in rain or high humidity with IP54 rating?

IP54 provides dust protection and splash resistance, so light rain or brief humid conditions are acceptable. However, we recommend using a simple rain cover to protect the winch motor and battery connections. In heavy rain or standing water, stop operation and wipe the rail and lubricate after the rain.

Q9: How long does one electric winch reset take? How many resets can a 12V 80AH battery support?

Each reset (pulling the slider back from the launch position to the initial position) takes about 1‑2 minutes. Battery consumption depends on load; typically, a fully charged battery can handle 20‑30 resets. We recommend checking battery voltage before each mission and carrying a spare.

Q10: Can the folded size (2200×570×620mm) fit into a regular SUV or pickup?

The length (2.2m) is relatively long; most SUVs may not have enough longitudinal space. We recommend using a pickup or small van. If you must use an SUV, you can fold the rear seats and place it diagonally, but ensure it is securely fastened to prevent sliding during driving.

Q11: What data do I need to provide for custom cradle/mounting? Will it affect the UAV’s CG?

We need the UAV model, 3D drawings or scan files of the bottom structure, the centre‑of‑gravity position, and the load capacity of the mounting points. Our engineers will design the mounting points to match the UAV’s CG and the rail release point, ensuring the CG remains unchanged and the take‑off attitude is stable. Please contact customer service for lead time and cost.
