Spectra UAV Pod

Contest Closed
The 3D Spectra UAV pod design will be utilized to mass produce a UA designed specifically for Search & Rescue (SAR) use. The hand built Spectra has been flown and used for the past 8 years, so it is a mature product that simply "just works"! The completely hollow design is strong but could benefit from bulkheads that would minimize impact on payload area.
Pod has already been CFD'd so those are known. We are looking to ease the construction of the ABS monocoque design. Interior considerations, hatch designs, access for batteries and electronics Widest hatch possible, closures, and options for payloads.
Overall length - 18"
Width - 8"
Root Chord - 13"
Pod depth - top to floor - 3.25
Catamaran runner - 1/2"
Inside dim runners - 4"
Don't Wants:
Don't want a complete redesign. The profile and overall shape should remain roughly the same.

I had to alter the shape of the upper section to enclose the camera case, I notice too that the lens projects below the skids an might be subject to damage when landing, I used G15 dimensions.

Batteries are : 4KAH 150x43X20mm and 286g. 3KAH are 148X43X16 and 231g weight

If the pod width is expanded to 8" the batteries may be situation in the nose so there is no need for battery mounts, holders, etc. Same goes for the camera, it may be a very small point and shoot or be a larger sensor so it is only important that the "shell" design be maintained and open as much as possible.

Everyone : Delete the air scoop on the side.

The two 7/16" holes need to be 1/8" from the bottom of the airfoil shape. The spar will run completely through the pod shell near the bottom of the floor.

I have prepared the 3D drawing and 2D drawing for the UAV project, and placed some main dimension there based on the information you provided. Now I hope that you can review the 2D drawing and let me know whether it is your expected shape and dimensions, at same time also provide more details: 1. Those battery's sizes and weight, 2. roughly size and weights for avionics, 3. Do you need battery boxs or similar like these staffs 4. Do you have requirment for mounting the camera. if you can provide more, we can do more analysis such as center gravity, inteference etc.

I have only 5 drawings to view. Four are from you, one from another. Is there someplace else for drawings?

You should have received 13 iterations of the design now with the updates requested. Final adjustments included increasing the width to 9" and the length to 19.5" and height to crown 4,25" to allow for camera and battery enclosure. The G15 has been accurately modelled from pictures of plan and elevation and I have included a nacelle for the tele lens. The dome for the Movie camera is now 3" as requested.

The intent is to have molds made from the final drawings via CNC machine. Any software that is exportable to a format that will be easily supported for that process is OK. Solidworks seems to have the widest following for that sort of end operation. If you can convince me otherwise, I will listen.

Hi - is it necessary for this to be created in Solidworks?
Sat, 11 Jan 2014 00:51:31 +0000

Actually that is a sub-floor and is required to keep the fully extended lens inside the pod. The sub-floor comes down approximately half way down the catamaran sides.
Also, the clear dome is a 3" dome so would need to be scaled up. Looking good though.

entry One image shows a recess in the bottom where the strut for the aerodynamic testing has been attached, is that required for the avionics ? on can it be left off.

Please look at additional pictures SM_Pod1 and SM_Pod2. This is the prototype that was vacuformed in ABS plastic and is a little smaller than specified here. The two images have the Panasonic Lumix camera installed and out showing the lens barrel and the width.
Please also note there is a 7/16" aluminum wing spar guide in these pictures as well. This goes all the way through the pod from side to side in two places.

If it can be exported to Solidworks compatible file format then OK. The idea is to be able to CNC machine a mold/plug

I have found some differences between the sketches and the dimensions you have provided. Are the sketches correct or the dimensions in the text?

I'm a student of aerospace engineering and really interested with your project.
Can I use Catia V5R19 for the design instead of Solid Works? Because I'm quite experienced with Catia.
I still can provide you with solid surface though.

Thank you for your consideration.

Hi, Sir,
I have learned your project, and have a few question and suggestions here:
1. As mentioned, you want remain the shape of the original UAV as much as possible, so I want to know whether it is possible that you can provide more detailed pictures,(please refer to the following sample pictures), Because I cannot attach some files here, so I have to attached a PDF file using “ submit”, please kindly find it.

Would like to use a minimum of a 5k mah battery or two 3k mah batteries
The avionics would fit in the rear third of the pod
The imager (payload) would be based around a Canon G15 or something of similar size.

The payload would need to be positioned in the forward third of the pod with the batteries placed near the nose to maintain center of gravity.

Hi Aeden,

Yes, I actually need a 3D model of my crude sketchings. The original is vacuformed from ABS so I have solid models of the top and bottom. Now I need a digital version of same.

Tue, 07 Jan 2014 00:11:44 +0000

This is Aeden from Lexington, KY. I am not very clear what you are asking? Are you asking 3D model of 3D Spectra UAV pod based on the pictures shown?

I am looking for an aerospace engineer to design a ducted fan for a personal aircraft. It is preferable that the engineer have previous experience with the design of fans or propellers before. The engine specs, such as horsepower and rpm are already known. I am expecting a 3D model of the fan blades along with the forces exerted on the propeller so that I could build the blades accordingly. I will construct the fan blades out of carbon fiber. It is also preferable if the Engineer could design the molds that the fan blades will be made from.
