Cancellation on publishing the U206 assembly project

Due to the restriction given by my Lecturer and the university, publishing of the project( on most project) in this blog has to be GROUNDED, including the aircraft Cessna U206 project. Huhu....

So, my posts will then goes on my journey and the aviation engineering OUTSIDE THE UNIVERSITY itself. So don't worry about this. Blogging on the aircraft engineering still goes on....

Fluid lines and fittings

The 2024 T3 pipe tubing is sawing and bending by using the bending tools

Using this faring tools, every open (inlet and oulet) of the tubing will be flaring. Like this tube which is 4/16 inch, the proper size to make the flaring with this flaring tools must also be compatible with that tube size.

Successful !

Play time..feeling something?

No sparking on bullets.No dangerous or do harm to our body. Remember, this is a just a toy-toy gun. I buy it at figura or gundam shops located in times square. Why do I buy this? Well thats because of I do like collecting replicas like gun and firearms -Thats is the hobby, you know.

About this one, this is almost alike to the guns.Their 'fire mechanisms' when click or pull the trigger like real-throw the plastic bullets and the shells can be removed from the chamber after have 'backfired'. But what does makes it difference is that the head slide of this pistol must always be sliding before pull the trigger. Hmm...

PS: Bilamana membuat pistol nih...saya cukup berasa seronok. Akan tetapi, ia juga membuatkan hatiku berasa sedih...mengapa? kerana bilamana aku berfikir seketika , aku berfikir betapa untungnya diri ini berada di negara ini ...dibesarkan di negara ini dengan pembelajaran...dibesarkan dengan kefahaman ilmu yang baik dan tanpa perlu mengangkat senjata seumpama ini. Sejata api pulak sekiranya mahu memperolehinya pun cukup susah...kena pulak ada lesen ...huhu

Bukan itu sahaja... malahan aku juga turut terasa bilamana membaca artikel di Palestinkini.net yang berbunyi begini:

Polis Rejim Zionis memukul kanak2 di Baitulmaqadis- barangnya dirampas dan diperlakukan hina hanya disebabkan memiliki pistol mainan?

Rakan-rakan sekalian...adakah anda berfikiran sedemikian juga? Alhamdulillah baguslah. Cuba ambil iktibar tentang bagaimana kesusahan yang dihadapi oleh saudara kita di Palestin.. Lihatlah, betapa mereka teruk ditekan dan ditindas oleh Zio4is akhirnya juga mengangkat senjata...biarpun ianya adalah penyapu atau batu sekalipun disebabkan hanya itulah yang mereka ada untuk memerangi...ya...untuk mendapatkan kembali tanah air mereka dan dikembalikan semula Baitulmuqadis yang dijajah ini.

Jadi apakah tugas kita dalam membantu mereka?...Adakah duduk diam membatu sahaja dan hanya mendengar dan mengutuk perbuatan zionis itu bagai angin berlalu begitu sahaja? adakah terus membiarkan anasir-anasir luar mejajahi pemikiran kita untuk tidak memboikot barangan keluar Zio4is ini? Masihkah kita dilekakan dengan 4 protokol zionis yang utama iaitu sex, song smoke dan sport?

Usahlah begitu...diriku dan saudaraku...tinggal-tinggalkanlah larangan itu!.. Masih banyak keperluan atas saudara kita perlu ditunaikan...

Saudara yang berada di kemboja kebuluran..

Tiada daging..tiada makanan berkhasiat

menunggu simpati dari kita

mengharapkan simpati kerjaan Kemboja jauh sekali

Lalu apa yang kita buat?

Saudara yang berada di tanah mereka ditindas oleh bangsa angkuh dan laknat

Persepakatan dan persaudaraan sesama meraka menjadi talian hayat

Roti...air ...barangan asasi mereka

dicatu dan dikongsi bersama

Masyarakat antarabangsa pula berbelah-bahagi

Lalu Apa yang kita buat?

Kini bulan puasa akan bakal tiba tidak lama lagi.sama-samalah kita doakan mereka supaya memperoleh kemudahan dan kebaikan di sisiNya. Sama-samalah kita berikan yang terbaik buat mereka ini. Ayuh bangunlah.....

Cable splicing- nicopress methods ...

Have you seen this type of cable before? This is the cables with different termination technique for the purpose of connecting the cable controls in aircraft. They are fit , durable and could maintain to full cable strength. To do this, things must be have is like cable cutter, gono-go gauge, caliper, nicopress sleeve and tools, and pliers also.

The center of the compression made first(with this tools) , then the compression nearest to thimble , and finally the compression at the end of the sleeve . After all the 3 compressions made, they are checked with special gauge. If they are properly made, the sleeve exactly fit the slot.

Cable that has been cut then goes to other process- swaging and nicopress

Access panel& blind rivet riverting

Equipment used

Bucking bar, Various File, Prick Punch, Hammer, Center Punch, Hammer, Burring tools, Cleco, Countersink, Lead Pencil/Marker, Deburring tool, Aviation Snips, ScalePneumatic drill, Cleco pier, Aluminium Sheet, Rivet Gun, Combination Square, Dividers, Rivet sets, Rivet, Rivet Gauge, Scale

b. Given

1. Material 2024 T3 0.032” [a. Skin(5.5”x 6.0”) b. Doublers(4.5”x 5”) c. Access panel(3.5”x4”) d. Metal sheet Strip(5.5”x0.75”)], Anchor nuts and screws MS21059L3& NAS603-6P 4 sets ,Rivet MS20426AD3-3; 32 rivets, Edge Distance ¼”, Rivet Pitch ½”, Cherry Max ; 3sets(Universal CR3213-4-02&CountersunkCR3212-4-02 1/8” )

Procedure:

1st, the sheet metal layout is transferred (exactly the same in the figure above) with all the metals separated from each other. Something have to be sure is that rivet pitches and edge distances is follow the AC43.13 1B/2A/ a/c repair manual/SRM procedures.

After that skin is taken and cut to the required hole for the access.File and deburr the hole to size. The rivet positions is marked with the center punch , drill thru it and holes get deburred.

Doublers(4 ½ “ x 5”) be taken and cut to the required hole size. The doublers must be place at the back of the skin and drill it thru the holes of the doublers. As the drill is finished, use cleco. Cleco are used to hold both pieces together firmly.

Use anchor nut to mark the holes . How we do?-palace and secure it to the piece, that’s all….

Em, another piece of metal with the size of (3 ½ “ x 4”) are to be cut, file and trimmed. This then should be used for access door on the combined sheet metal.

Ok, now the the best part itself- coating the Alodine(use for preventing the corrosion). Clean it and dry it for half an hour.

By using the given machined screws, close the access door.

Now, the last part of sheet metal- the bottom metal sheet strip must be mark at the desired holes for the Cherry max installation. As you already see here, there are two types of Cherrymax rivets -3 countersunk and 4 universal heads) installed by using the pop rivet gun.

Flush patch

2. flush patch-

Tools-same as to what we need for surface patch.

What we do;
Calculate ed,rd,nr n rl. Cut the sheet metal following the diagram of flush metal on a piece of sheet that patched onto that surface. Filling it, (Note:make the center punch befor drill) make a hole, (the plug and skin) with diameter of 3/32 inch. On the skin, make countersunk with using the countersink drill. Then rivet both skin and patch. At the center, rivet the plug onto the patch.

Once finished, clean the flush patch with the soap. Soak it in the alodine to prevent it from corrosion for 5 minutes. Clean the flush patch with water and dried it well

The skin countersink is looks like 'flower'- does happen because of unpropagated adjustment and maintaining the countersinking drills to the skin.

Once finished, clean the flush patch with the soap. Soak it in the alodine to prevent it from corrosion for 5 minutes. Clean the flush patch with water and dried it well

Next---> will be Door Access panel

Surface patch

1.Surface patch====

what we need;

universal rivet ms470, sketch of the patch and panel, sand paper, tools; rivet gun with straight sets, deburring tools, gleco, filling tools ,bucking bars, fastener pliers

what we do;

calculate the rivert including Ed(edge distance), Rd( rivet diameter),Nr(no of rivet),rl(rivet length).Then sketch onto the sheet of paper, make the photocopy, patch it onto the 2024 sheet metal. When done cut it through its size and shape of the patch and skins.

Filling the edge of the sheet metal, make the hole for the riveting on both skins and patch. Gleco by using sheet fastener pliers.

Cut the bottom of the rivet by using the rivet cutter. Say if the rd which is 3/32 so must add 2 plies of bottom steel of the rivet cutter to make it cut and firm to the patch and skin . Put that rivet into the hole of patch and skins and begin to riveting by using rivet gun and bucking bars. The shop head that was shaped from the pressed of bucking bars must be ½ to the original length of the rivet (that is the length of the rivet behind the panel).

Next----> will be on flush patch next time

The wiring project

Last Thursday, 14 Jan, we have been delivered new task to be done in lab. The task is simple. Cut the wire insulator, crimping the other parts of the wire, twisted the wire, soldered it, cover that area with the tube insulator and shrink it with heater. But all the task must be done surely by follow the labsheet that have been given to us. Here is how we do it...

Both wire are twisted. Surely have to make it tight and grip well

Soldered onto its surface. To make this perfectly, one must heat the wire first and then soldered it.

The solder wire connection covered with shrinking tube. Then exposed onto the heater gun so that the shrinking tube shrink and grip nicely.
